A chart will not tell you where corn prices are going. It will show you the trend, show you the price areas where a contract has repeatedly stopped, and give you somewhere specific to put your next offer — whether you are pricing new crop before harvest or selling out of the bin in February.

Can a chart tell me where corn prices are going?
No chart predicts price. Support and resistance aren’t a forecast, a trend isn’t a promise, and every level on every chart eventually fails. Anyone telling you a chart says corn is going to $5.20 is telling you their opinion, not reading the chart.
So the useful question is not “where is corn going?” It is one only you can answer: at what prices am I willing to price part of this crop? Three things go into that answer.
- What you know about supply and demand tells you whether corn looks cheap or expensive, and whether you should be selling at all.
- Your own numbers — cost of production, insurance guarantee, storage cost, cash flow — tell you what price actually works on your farm.
- The chart shows where this market has run into buyers and sellers before, and gives you a place to put the offer.
Past performance is not indicative of future results.
The rest of this page covers the third one and how it fits with the other two. The next section shows the finished product first, so you can see where this is going.
What this looks like: four offers into one price area
First, how to read the chart itself. These are candlestick charts, which you will see on DTN, Barchart, or your broker’s platform. Each candle is one trading day.
Now the plan. The shaded band is an area where this contract stalled three times. The four dashed lines are resting sale offers.
Two offers sit below the band, one inside it and one above. If the rally runs out early, the two lower offers have still priced half of what you set aside. If it carries into the band, the third is working. If the market breaks out, the fourth is there, and it cost nothing to leave it.
Now convert that to what your elevator pays
This is the step producers skip, and in our opinion, it matters most. A futures target is not a cash price. You receive the futures price plus or minus your local basis for that delivery period, and basis varies by elevator, month, and year.
If the contract you are pricing against reaches $4.78 and your elevator is bidding 30 cents under it for that delivery period, your indicated cash price is $4.48. That — not $4.78 — is the number to compare against your farm’s cash breakeven.
| If futures reach | Your basis | Indicated cash price |
|---|---|---|
| $4.56 | 30 under | $4.26 |
| $4.68 | 30 under | $4.38 |
| $4.78 | 30 under | $4.48 |
| $4.88 | 30 under | $4.58 |
Illustrative. Thirty under is an example, not a quote. Basis differs by elevator, by delivery period, and by year — use your own bid for the period you intend to fill.
Run that conversion before you decide a level is worth an offer. A chart area that looks attractive at $4.80 futures may or may not clear your costs once basis is applied, and the answer changes between a river terminal and an interior elevator in the same week. Our guide to how corn basis works covers how to track yours.
What is support and resistance on a corn chart?
Support and resistance are record behavior, not explain it. What the chart establishes is narrow and useful: corn rallied into this area three times and closed below it each time. Something was meeting those rallies.
Who, exactly, the chart cannot say. Plausible buying candidates include end users, exporters, and traders covering shorts; plausible selling candidates include growers pricing grain and traders taking profits. That is a reasonable inference about a grain market, not something the candles establish, and it is worth keeping the two apart in your own thinking.
The wicks are the part that matters
A line chart plots closes, so it hides whether price reached a level at all. A candle shows the reach and the result in one mark — the wick stabs into the area, the body closes back outside it. That is what “the market tested $4.80 and failed” actually looks like on a screen.
Why they are zones, not lines
You will see people draw a single line at $4.75 and treat it as a hard number. Highs cluster in a range — $4.75, $4.80, $4.78 — and the useful thing is the area those highs occupy, not any one of them. Treating a zone as a precise price is how a grower ends up with an offer at $4.81 that never fills while the market turns at $4.80.
What does a trend on a corn chart tell you?
“The trend is your friend” is often sold as though it predicts something. It describes what has already happened, in a form that is easier to read than a column of settlements.
Here is where it earns its place in a marketing plan. A market making higher lows is one where buying keeps appearing earlier than last time. That is a reason to be patient with unpriced bushels and to set your offers higher, not lower. When the pattern stops — a low comes in under the previous one, or the market goes flat for weeks after months of climbing — the condition that justified your patience is no longer on the chart.
That is not a sell signal. It is a prompt to go back and check whether the reason you were waiting still exists in the fundamentals. If the balance sheet still supports higher prices, you may be looking at a pause. If it does not, you now have two things pointing the same way.
How do I find these areas on a corn chart?
First: which contract should you be looking at?
The chart you want is the one for the delivery period you actually intend to price into. That is a different contract for a grower pricing new crop in July than for one selling out of the bin in February, and each contract has its own areas. Where December stopped tells you nothing about where March has stopped.
| If the grain leaves your farm… | Price against | What you are reading |
|---|---|---|
| At harvest, priced ahead of time | December | The new-crop contract. Where the market has stopped during the growing season. |
| Out of the bin, late autumn into winter | March | The first deferred month. Its areas are set by post-harvest trade, not by summer weather. |
| Late winter into spring | May | Often where stored bushels get priced, alongside the carry. |
| Spring into summer | July | The last old-crop month before new supply is in view. |
Corn futures trade March, May, July, September, and December.
If you are holding grain, the gap between those contracts is its own decision. The difference between December and March, or March and May, is the carry the market pays you to store, and whether it beats your real storage cost is a separate question from where you set the offer. Our guide on selling versus storing works through that side of it.
- Use the right contract — see the table above. Never use a continuous front-month chart, which splices contracts together and shows areas that exist in none of them. (Use continuous charts for longer-term trends across contract rollovers, but use the specific delivery-month chart for sale targets because roll adjustments can distort historical price levels and support or resistance.)
- Zoom out before you zoom in. Start with a weekly chart going back a year or two. What shows up on a weekly chart is what many people look at.
- Mark where it turned more than once. Not every high and low—only the ones where the market reversed, and the move stuck for several weeks.
- Draw zones, not lines. If the highs came in at $4.75, $4.82, and $4.78, your area is roughly $4.75 to $4.82. Write down both numbers.
- Note the trend while you are there. Are the lows rising, falling, or flat over the period you are looking at? One word is enough.
- Write down how many touches and over what period. Three touches in eight months means more than two in three weeks. If you cannot answer that question, you do not have an area yet.
- Convert each candidate price to cash. Apply your basis before you decide whether that area is worth an offer.
The three inputs to every corn sale decision
| Input | The question it answers | What it cannot tell you |
|---|---|---|
| Fundamentals carryout, export pace, yield, demand |
Is this market historically cheap or expensive? Should I be selling at all? | What price to ask, or when |
| Your own numbers cost of production, insurance guarantee, storage cost, basis |
What price actually works on my farm? What can I afford to wait for? | Anything about the market |
| The chart trend, support, resistance |
Which direction has this market been moving, and where has it stopped before? | Where price is going, or whether the area will hold this time |
Each row is blind to what the other two see. That is why the chart is a supplement, not a substitute.
Most marketing mistakes come from relying on a single input. Relying purely on fundamentals leaves you with a strong opinion and no plan to execute it. Relying solely on the chart can lead you to place offers at prices that may not cover your costs. Working purely from your own numbers can lead you to take any price that clears breakeven, even when the market was about to pay considerably more.
For 2026 crop corn, the insurance numbers give another reference point. The projected price was $4.62, and the harvest price came in at $4.75. If you carry Revenue Protection, the higher of the two sets your guarantee, which changes what an unpriced bushel is worth to you. Confirm both figures against your own policy documents before you rely on them.
What if the chart and the fundamentals disagree?
When they agree, you have a stronger case for acting and for the size of the action. When they disagree, that gap is itself information — often that something is in the market that is not yet in the published numbers.
When buyers and sellers disagree on price, a common response is to sell less of the crop rather than commit the entire quantity at one price.
When they point the same way
Say the balance sheet has tightened — carryout came down, export sales are running ahead of pace — and the chart shows a market making higher lows and pushing into an area it failed at twice before. Two independent sources are describing the same situation.
That does not mean prices will rise. It means your case for patience has more support than either input alone, and you can reasonably set higher offers and wider spreads.
When they point opposite ways
| What you see | One common interpretation | A possible response |
|---|---|---|
| Fundamentals look supportive, but price keeps making lower highs | The bullish case may already be priced in, or sellers may be acting on something the published numbers don’t yet show. | Take price into strength rather than holding out for the number your fundamental read says you deserve. |
| Fundamentals look heavy, but the market keeps stopping in the same area | Demand may be present that the balance sheet has not captured yet — an export program, better domestic use, or producers not selling. | Be careful about clearing the bin into a market that is refusing to go down. Scale out instead. |
Interpretations are general and will not apply to every situation.
And sometimes neither is right. A divergence can mean the market is between stories and will resolve on news that has not happened yet. You will not know which case you were in until afterward.
What does it mean when corn breaks through support?
One widely cited explanation is that buyers who entered in the area are now holding losses and sell when price returns to their entry. Whether that is the mechanism in any given case, the pattern is what you can observe: the area that used to stop declines starts stopping rallies.
Notice what the candles do after the break. The rallies push a wick up into the old area and close below it — the mirror image of what they were doing before, when wicks dipped in and closed above. Same area, opposite behavior.
What to do with it as a marketer. If your area was $4.18 to $4.25 and the market breaks under it, two things follow. Offers you had working above are much less likely to be reached in the near term, and the next rally may struggle around that old area. That may be your realistic opportunity now, rather than at last month’s price.
It is also the moment to check the fundamentals again. If the balance sheet has not changed, a break may be positioning rather than a change in the market’s situation. If the balance sheet has changed too, you have both inputs pointing the same way and a different decision in front of you.
When should I ignore the chart entirely?
The gap on that chart is worth a second look. Price did not travel through the area — it opened above it. There was no chance to sell at $4.80 that morning, because $4.80 never traded. An offer resting in that area filled at the open, or not at all, depending on the order type. A line chart would not have shown you the gap happened.
Every area on a chart records what happened under one set of facts. Change the facts — a yield cut, a new export program, a drought in a competing exporter — and the behavior that created the area may not repeat. The chart couldn’t know because the information didn’t exist when those highs were made.
The scheduled dates are on the calendar, and you can plan around them. USDA’s WASDE and Crop Production reports, Grain Stocks, and Prospective Plantings can all move corn through an area in one session, and limit moves happen on those days. If you have resting offers working into a report, you have made a decision about that report whether you meant to or not.
What does chart analysis actually give a corn grower?
What it genuinely gives you
- Price points decided when you are calm. The hardest part of grain marketing is not knowing what to do; it is doing it while the market is moving and the bin is full. A written ladder gets acted on.
- A structure for scaling out. Chart areas give you somewhere to put the rungs, so scaling out has a basis beyond guesswork.
- A second view on your fundamental read. When the chart agrees, your plan has more behind it. When it disagrees, you have a reason to make a smaller decision.
- An early prompt that your plan has gone stale. A trend that stops making higher lows, or an area that breaks, sends you back to the balance sheet.
- A common language with your advisor and your broker.
What it does not give you
- Any ability to predict price. Areas fail regularly, and nothing on the chart tells you in advance which ones will.
- Protection from a fundamental shock. A yield surprise goes through an area as if it weren’t there.
- A cash price. Every level on the chart is futures. Basis stands between it and what you are paid.
- A substitute for knowing your cost of production. A chart will happily show you an attractive-looking target that doesn’t cover your costs.
- Precision. Areas are approximate. Anyone quoting support to the quarter cent is overstating what the method can do.
- A reason to trade. Using chart areas to place sale offers against bushels you own is marketing. Buying and selling futures on those areas without grain behind them is speculating, and it carries a different risk profile.
You may already be paying for this
Many grain farmers say they do not use technical analysis. Many are paying for it anyway.
If you subscribe to a market advisory service, a newsletter, or a daily audio comment, there is a fair chance the person writing it is looking at a chart. When an advisor says corn “needs to hold $4.20” or “has resistance at $4.80,” that is support and resistance. The language arrives secondhand, with the chart left out of the room.
Buying market advice is normal for commercial growers. A 2006 study of U.S. crop farmers, based on a 2000 survey, found that about 82 percent of respondents used a market advisory service, on operations averaging roughly 1,900 acres. Two caveats accompany that number: it is twenty-five years old, and the farmers surveyed came from a market information company’s customer directory, so they were more likely than average to buy advice in the first place. The question itself is older still — a 1982 South Dakota State University thesis was titled, plainly enough, An Evaluation of Technical Analysis as a Marketing Tool for Farmers.
Why that matters to you. If chart reasoning is already reaching you through someone else’s recommendation, you are better off understanding it than not — not to replace your advisor, but to ask a better question when the advice arrives.
“You say there’s resistance at $4.80. How many times has the market stopped there, over what period, and what does that work out to in cash at my elevator?”
The research record deserves the same honesty. Academics have studied whether market advisory services — many of which lean on charting — beat straightforward benchmarks such as pricing evenly through the year. Findings across multiple crop years have generally been humbling for the services. The case for charting is not that it beats the market. It turns a marketing intention into numbers you can act on.
A checklist
- Do you know your cash cost of production per bushel? If not, stop here. Everything else is decoration.
- What do the fundamentals say about whether you should be selling at all? Carryout, export pace, the last WASDE.
- Are you looking at the contract that matches when the grain leaves your farm? Not a continuous front-month chart.
- What is the trend doing? Higher lows, lower highs, or flat. One word.
- How many times has the market stopped in this area, and over what period? If you cannot answer, it is not an area yet.
- Have you written it as a range? Two numbers, not one.
- What is your basis for that delivery period? Convert every candidate futures price to cash before going further.
- Does the cash figure clear your cash breakeven? Compare like with like, not futures against a cash cost.
- Do the chart and the fundamentals agree? If yes, act at normal size. If no, make the decision smaller.
- Have you split the offer? One price is a bet. Three or four is a plan.
- What kind of order is it, and what happens on a gap? A board order, a cash contract, and a hedge-to-arrive behave differently.
- What is on the USDA calendar between now and your offer? A report can take price through your whole ladder in one session, either way.
- What happens if the area breaks instead? Decide now, not while it is happening.

Questions growers ask
No. Everything on a futures chart is a futures price. You are paid that futures price plus or minus your local basis for the delivery period, and basis differs by elevator, month, and year. If the contract you are pricing against reaches $4.78 and your elevator is bidding 30 cents under it, the indicated cash price is $4.48. Convert every candidate target to cash before deciding whether an area is worth an offer, and compare that cash figure against a cash cost of production.
A chart shows the market’s direction and the price areas where buyers and sellers have repeatedly acted. Growers use that to set sale-price targets in advance and place scaled offers, rather than deciding under pressure. It supplements knowledge of supply and demand and a grower’s own cost of production; it does not replace either.
No. Support, resistance and trends describe what has already happened; they do not forecast where price will go. Levels fail regularly, and nothing on a chart indicates in advance which ones will hold. For a grower, the practical value is setting price targets ahead of time and testing a fundamental view against a second source of information.
Support is a price zone where buying has repeatedly stopped a futures contract’s decline. Resistance is a zone where selling has repeatedly stalled a rally. Both are areas, not exact prices, and both reflect decisions by real buyers and sellers, such as end users buying value and farmers selling into strength.
A trend tells you the market’s direction and whether that movement is still intact. An uptrend is a series of higher lows; a downtrend is a series of lower highs. It does not indicate how far a move will go or when it will end. For a grower, the useful signal is usually when a trend stops behaving that way, prompting you to recheck the fundamentals.
Each candlestick represents one trading day. The rectangular body spans the open and the close, and the thin wicks above and below mark the day’s high and low. A line chart plots only closing prices, so it hides how far price traveled during the session. For support and resistance, that hidden part is the point: a wick reaching into a zone and a body closing back outside it is what a failed test of a level looks like.
The one that matches when the grain leaves your farm. New crop priced ahead of harvest goes against December; bushels sold out of the bin in late autumn or winter go against March; stored grain moving in spring goes against May, and into summer, July. Each contract has its own support and resistance, so a level on the December chart tells you nothing about where March has stopped. The spread between two contracts is the carry the market pays you to store, a separate decision from where you place the offer.
Open a daily or weekly chart of the contract you intend to price against — December for new crop priced ahead of harvest, March or May for bushels sold out of the bin — look back six to twelve months, and mark the areas where the market reversed more than once. Two touches make a zone worth noting; three or more make it worth planning around. Write the zone as a range, such as $4.75 to $4.82, rather than a single price.
Treat the disagreement as information, not a choice to take sides. If supply and demand look supportive but price keeps making lower highs, the bullish case may already be priced in, or sellers may be acting on something not yet published. If fundamentals look heavy but support holds, demand may be present that the balance sheet hasn’t captured. In either case, a common response is to make a smaller decision, price a smaller share, or spread offers more widely, rather than bet on which input is right.
Both, in that order. Supply and demand tell you whether prices are historically low or expensive and whether you should be selling at all. Your cost of production tells you what price works on your farm. The chart then helps you decide where to place the offer. When the chart and the fundamentals disagree, most growers reduce the size of the decision rather than acting on one input alone.
Most growers using a scaled approach work with three to five offers covering a portion of expected production, spaced across and above a resistance zone. A single offer at one price is either reached too early or not at all, and you can’t know which in advance. The right number and the share of the crop on each are decisions for your own operation.
It means the buying that defended that zone is no longer sufficient. Breaks are often followed by further selling, and the old support zone often becomes resistance on subsequent rallies because buyers who entered there tend to sell when price returns to their entry. A single day below a zone is not the same as a failed zone.
It uses the same concepts applied to a different job. A trader may use support, resistance, and trend to enter and exit positions for profit. A grower uses them to decide where to price existing bushels. The second is marketing against physical production; the first is speculating, and it carries a different risk profile.
Many do, at least in part. When a recommendation refers to a price that corn needs to hold, or a level where it should run into selling, that is support and resistance whether or not the word chart is used. A reasonable question to ask any advisor quoting a level is how many times the market has turned at it, over what period, and whether it lines up with the balance sheet.
Weekly and daily charts covering six to twelve months suit marketing decisions because that window roughly matches how long the current supply-and-demand picture has been in place. Intraday charts are built for trading decisions and are generally not useful for deciding where to price grain.
