Entries get all the attention. Yet a position's result is set entirely by how it ends, and that decision is made under pressure, with money at stake and an opinion to defend.
This lesson is about making the exit decision before those conditions apply.
Adjusting versus hiding
Adjusting a position means changing its structure because the situation changed. Hiding means changing it because you do not want to take the loss.
They look identical on the screen. The difference is entirely in the reason, and there is a clean test:
Would I put this new position on today, from flat, at these prices?
If yes, it is an adjustment — you are choosing a position you would independently want. If no, you are avoiding a realisation, and you have just made the position worse while feeling productive.
Legitimate adjustments
Rolling out — closing a near expiry and reopening further out. Buys time. Legitimate when your thesis needs longer and still holds. Illegitimate when it is only to avoid booking a loss this week.
Rolling up or down — moving strikes to follow price. Legitimate when your view has genuinely shifted.
Adding a protective leg — converting a naked short into a spread. Almost always sensible when a position has moved against you, because it caps a tail that is now live rather than theoretical.
Closing half. Underrated. Reduces exposure without requiring you to be right about timing, and it works when you are uncertain — which is most of the time.
The adjustment that destroys accounts
Rolling a loser out and up in size.
The position is losing. You close it, reopen further out with more contracts so the extra premium covers the loss, and the account shows no realised damage.
You have now increased size on a position that is already wrong, and moved your exposure to a larger, later version of the same bet. Do it twice and the position is several times the original size with an unchanged thesis.
This is the mechanism behind most blown F&O accounts. It never feels like a gamble at the time — it feels like management.
Exit rules that work
The useful ones are decided before entry and are mechanical.
A loss multiple. For credit strategies, exit at a fixed multiple of the credit received — 2× is common. Collect ₹4,000, exit at ₹8,000 of loss. Bounded, unambiguous, no judgement required in the moment.
A profit target. For premium selling, taking 50% of maximum profit early is standard practice. The last half of the profit takes disproportionately longer and carries the tail risk of the whole trade.
A time stop. Exit at a fixed days-to-expiry regardless of P&L. Avoids the gamma zone entirely.
A thesis stop. Exit when the reason you entered stops being true, even if you are profitable. The strongest of the four and the least used.
Take profits earlier than feels right
For a short premium position, the profit curve is heavily front-loaded. Reaching 50% of maximum profit typically takes a fraction of the time that the remaining 50% requires.
Meanwhile, the risk does not decline in proportion. You are holding the full tail exposure to collect the slowest, smallest part of the gain.
Closing at 50% and redeploying is usually better on a risk-adjusted basis than holding to expiry — which contradicts the instinct to "let it expire worthless and keep everything."
Exiting a multi-leg position
Close it as a structure, not leg by leg. Legging out leaves you holding an unintended naked position between fills, exactly as legging in does.
Close the short legs first if you must go one at a time. That way any exposure window is on the protected side.
Do not hold the last cheap leg. Traders routinely close the profitable side of a spread and keep the remaining leg "since it is nearly worthless." That leftover leg is a naked position you did not choose to open, and it is the one that is live during a gap.
The written plan
Before entering, write down four things:
- Why I am in — the thesis, in one sentence
- What ends it — the price, level or event that says I am wrong
- Where I take profit — a number, not a feeling
- What would make me adjust — and what an acceptable adjustment looks like
Four lines, thirty seconds. Their whole purpose is to make the exit decision at a moment when you have no money on the line and no position to defend — because once you do, every input to that decision is compromised.

What to take away
- Adjusting changes a position because the situation changed. Hiding avoids a loss. Use the from-flat test.
- Never increase size to repair a loss. If a repair needs more contracts, it is a new larger bet.
- Decide exits before entry: loss multiple, profit target, time stop, thesis stop.
- Take short-premium profits at ~50% — the rest is slow and carries the whole tail.
- Exit multi-leg positions as a structure; short legs first if you must.
- Never keep the leftover cheap leg. It is a naked position you did not choose.
