Volume, Open Interest, and Delivery

What OI means, who delivers, who cash-settles.

Intermediate 5 min read Course 18 of 60

Course 18 of 60 in the futures hub. The object is volume, OI, cash settle, and who actually delivers.

Open Interest Is Not Volume

Open Interest Is Not Volume. The honest one-sentence object of this lesson is volume, OI, cash settle, and who actually delivers. If you cannot say that without opening a platform, you will size the wrong clock. The failure mode that actually hurts accounts is reading volume on a continuous chart as if it were one month. Write the object, then size. Educational only.

Analog, not identity: delivery is a process, not a morality play. Crypto perpetuals and cash equities are a different lesson. Different machine, different hours, different ruin path. Contrast the object with forex hub rather than treating every product as the same machine.

1. Volume vs OI

Volume vs OI is the first working definition. Volume, OI, cash settle, and who actually delivers. People skip this because a chart is easier than a specification. A chart is not a spec. If you cannot explain Volume, Open Interest, and Delivery to a skeptical friend without a screenshot, you do not understand it yet.

Keep a crib note: object, invalidation, dollar cap. Reading volume on a continuous chart as if it were one month is how cribs get skipped. Do not skip. For the arithmetic habit, use stop calculator until dollars are boring.

Volume is today's traffic. Open interest is the open book Volume Contracts traded todayCan be high on a close-outDoes not mean new risk Open interest Open longs = open shortsRises when new risk is addedFalls when risk is closed

2. Who holds through expiry

Who holds through expiry. Convert every pretty statement into dollars. The arithmetic below is illustration — live ticks, pips, and margins change. Re-read the live schedule.

If OI is migrating and your size is $163 in a dying month, you may be the liquidity. Roll or flatten.

If that arithmetic already exceeds your cap, the lesson is over: pass or step down in size. Passing is a position. Confirm the dollar translation with margin calculator so the notebook and the statement agree.

3. Cash settle vs delivery

Cash settle vs delivery. Context is not a trigger. Delivery is a process, not a morality play. Use context to veto, not to force a click.

When in doubt, name volume, OI, cash settle, and who actually delivers again. If the sentence changed, you changed trades without admitting it. Related structure: free calculators.

4. Specs vs commercials

Specs vs commercials. Process beats mood. Write the rule that fires without a debate at the worst moment. If the rule is 'I'll see how I feel,' you do not have a rule.

Stops, flatten policies, and session boundaries belong in the same notebook as the thesis for Volume, Open Interest, and Delivery. If the stop is a price, convert it with listed venues after you already know the tick or pip.

5. Why you probably flatten

Why you probably flatten. Fair warning: specs, leverage caps, and dealer rules change over time. The live document wins. Educational only. Not NFA, tax, or a solicitation.

Re-read primary docs before you add size on the object of Volume, Open Interest, and Delivery. See also previous lesson when the confusion is the venue layer, not the chart.

Are you a commercial with a warehouse? Do you make or take the physical? If you already trade for a firm your desk has the manual Flatten before notice retail default

6. Mistakes, limits, takeaways

Mistakes: reading volume on a continuous chart as if it were one month; copying size from a stream; ignoring costs; mixing this machine with crypto perpetuals or cash equities. Another: treating Volume, Open Interest, and Delivery as advanced because the vocabulary is long rather than because the dollar cap is written. If the sister asset class is the real mix-up, next lesson before you add size.

Maps go stale. Delivery is a process, not a morality play. If this lesson and the live spec or statement disagree, the live document wins.

Volume is today; open interest is who is still there

Volume counts contracts traded in a session. Open interest counts contracts still held overnight. A day with huge volume and flat open interest means a lot of positions changed hands without the overall bet getting bigger.

For most retail traders the practical use is simple: trade the month where volume and open interest are concentrated, and get out before the delivery process starts if your contract is physically settled. Reading deeper meaning into small daily changes in open interest is mostly guesswork. I'd use it as background, not as a signal.

Before you move on

  • Object: volume, OI, cash settle, and who actually delivers.
  • Failure: reading volume on a continuous chart as if it were one month.
  • Dollars first, leverage last.
  • Skip the window you cannot survive.

Volume, Open Interest, and Delivery can remain a useful lesson and a poor live habit at the wrong size. Educational only. Not a recommendation to buy, sell, or hold any contract or pair.
