Pre-Trade Plan, Stress Test & Review

I don't need to be fearless to trade well — I just need a plan I made before I was scared, and the discipline to follow it and learn from it afterward.

• Write a pre-trade plan that fixes entry, exit target, stop-loss, and position size before entering a derivatives trade.
• Convert a vague worry about a trade into a specific worst-case rupee number using a stress test, before risking any money.
• Review a closed trade by judging whether the process was sound, separately from whether the outcome was a win or a loss.
• Explain why judging a trade by its outcome alone (rather than its process) leads to the wrong lessons over time.

Here's why this matters: the biggest danger in a derivatives trade isn't usually the market — it's you, thirty seconds after you've placed the trade, watching the price move. That's when fear or greed take over and start rewriting your decisions. The only way to stop that is to make the real decisions earlier, while you're still calm. That's what this whole routine is for.

The routine has three checkpoints, and each one answers a question the others can't.

1. Pre-Trade Plan. Before you enter, you write down four things: your entry price, your exit target (where you'll book profit), your stop-loss (where you'll cut the loss), and your position size (how much of your money this trade is allowed to use). Writing these down before entering means your future, anxious self doesn't get to renegotiate them later.

A reckless trade can win by luck. A disciplined trade can still lose.

2. Stress Test. A plan tells you what you intend to do. It doesn't tell you what it will actually cost if things go wrong. So you ask one direct question: "If this hits my stop-loss, exactly how many rupees do I lose?" Not "a lot" or "it could be risky" — an actual number, in rupees, decided before you risk a single paisa. That number is what turns a fuzzy worry into something you can look at and decide: can I actually accept this?

3. Post-Trade Review. After the trade closes — whether you made money or lost it — you don't just check the profit and loss. You check the process: did you enter where you planned? Did you exit at your stop-loss or target, or did you panic and deviate? Was your stress-tested number close to reality? This is the step most people skip, because a win feels like proof you did everything right, and a loss feels like proof you did everything wrong. Neither is necessarily true.

A reckless trade can win by luck. A disciplined trade can still lose — markets don't owe anyone a good outcome, even when the process is perfect.

That's why review has to look at process, separately from outcome — otherwise a lucky win teaches you to repeat something reckless, and an unlucky loss teaches you to abandon something sound. Reviewing this way is what actually makes your next decision better than this one, regardless of how this trade turned out.

Take Rohan. He has ₹50,000 set aside, and he's watching Nifty ahead of a heavy earnings week, thinking about buying call options.

Before he enters, he fills out his Pre-Trade Plan on a notes app: entry at a call premium of ₹120, exit target at ₹156 (a 30% gain, where he'll book profit), stop-loss at ₹90 (a 25% fall in premium, where he'll cut the loss), and position size capped at ₹10,000 — just one-fifth of his ₹50,000, so one bad trade can't wreck his capital.

Then he stress-tests it. He asks himself the direct question: if Nifty moves sharply against him on a bad-news day and his stop-loss hits, exactly how many rupees does he lose? With ₹10,000 committed and a 25% stop-loss, the answer is ₹2,500. Not "some money" — ₹2,500, written down, before he places the order. He looks at that number and decides he can live with it.

He enters the trade. Three days later, an unexpected policy announcement moves the market hard, and his stop-loss hits. He's down ₹2,500 — a loss.

Now comes the Post-Trade Review, and this is where Rohan does something most people skip: he checks the process, not just the money. Did he enter at ₹120 as planned? Yes. Did he exit at his stop-loss, or did he freeze and hope it would bounce back? He exited exactly as planned. Was his worst-case estimate of ₹2,500 accurate? Yes, almost to the rupee.

Rohan lost money on this trade. But his process was sound — he planned it, sized it sensibly, stuck to his exit, and the loss was exactly the size he'd already accepted before entering. That's a good decision with a bad outcome, and reviewing it this way tells him to keep trading this way, not to panic and abandon his method.

Point: The three checkpoints are not abstract ideas — they are concrete, fillable steps that can be applied to any real trade, and the review step judges the decision-making, not just the money made or lost.

• Judging whether a trade was 'good' purely by whether it made money. — The profit or loss is the visible, immediate result, so it's tempting to treat it as proof of good or bad decision-making. Fix: Review the process separately from the outcome: did you follow your plan, size your position correctly, and exit as decided? A losing trade with a sound process is still a good decision.
• Treating a general feeling of 'this trade is risky' as if the risk is already managed. — Acknowledging risk feels like the same thing as controlling it, and putting an exact number on it can feel unnecessary or overly technical. Fix: Before entering, state your worst case as a specific rupee number at your stop-loss — vague unease isn't risk management until it's a number you've written down and accepted.
• Expecting the plan-stress-review checklist to guarantee a good outcome or prevent losses. — A structured process feels like it should produce safety, and people want certainty when real money is involved. Fix: Remember the checklist makes decisions more sound under uncertainty — it doesn't remove risk. Losses can still happen even when every step was followed perfectly.

• Decide your entry, exit target, stop-loss, and position size in writing before you enter a trade — not after emotion arrives.
• A stress test turns vague fear into one specific rupee number you accept before risking any money.
• After a trade closes, review whether you followed your process — not just whether you made or lost money.
• A disciplined process can still lose money, and a reckless one can still win by luck — only reviewing the process teaches you the right lesson.
• This checklist makes your decisions more sound under uncertainty; it does not guarantee profit or remove real risk.

Q1. Which four things should a Pre-Trade Plan fix in writing before you enter a derivatives trade?

• Entry price, exit target, stop-loss, and position size
• Entry price, broker name, market mood, and lucky number
• Exit target, stop-loss, news headlines, and friend's opinion
• Position size, entry price, exit target, and expected profit percentage of the whole market Answer: Entry price, exit target, stop-loss, and position size — A Pre-Trade Plan locks in these four decisions while you're calm, so your in-the-moment self can't renegotiate them once money is at risk.

Q2. What does a Stress Test actually give you that a general feeling of 'this trade is risky' does not?

• A specific rupee number for the worst-case loss, decided before entering
• A guarantee that the trade will not lose money
• A prediction of exactly which direction the market will move
• A reason to skip writing a pre-trade plan Answer: A specific rupee number for the worst-case loss, decided before entering — Vague unease isn't risk management. A stress test turns that unease into an exact, ownable rupee number at your stop-loss, before you risk anything.

Q3. A trader followed her plan exactly, sized her position sensibly, and exited at her stop-loss as decided — but the trade still lost money. Was this a good decision? Answer: True — Process and outcome are different things. A sound, disciplined process can still lose money because markets don't guarantee results — reviewing the process, not just the rupee outcome, is what tells you whether the decision itself was good.

Q4. Priya has ₹40,000 set aside and decides to risk only ₹8,000 on a Nifty options trade, with a stop-loss set at a 25% fall in premium. What should she write down as her stress-tested worst-case loss before entering? Answer: ₹2,000 — 25% of the ₹8,000 she has committed to this trade is ₹2,000. Stating this exact number before entering is what makes the risk ownable instead of just a vague worry.

Q5. A trader enters a trade with no written plan, exits on a gut feeling, and makes a large profit. He tells his friends: "See, my instincts are great, I don't need all that planning stuff." Does the profit prove his no-plan approach works? Reveal: Weak: yes, the result speaks for itself, instincts worked. Strong: the profit doesn't prove the process was good — a reckless trade can still win by luck; reviewing the process separately from the outcome is exactly what stops a lucky win from teaching the wrong lesson.
