Risk–Reward

A trade can be measured well and still lose — that doesn't make the measuring wrong, it makes it real.

• Calculate a trade's risk-reward ratio by dividing potential rupee gain by potential rupee loss, using the entry, stop-loss, and target prices.
• Explain why a favourable risk-reward ratio changes whether a bet is worth taking, not whether that specific trade will win.
• Identify why calculating risk-reward after entering a trade fails to protect a trader, and why entry, stop-loss, and target must be fixed beforehand.

Here's why this number matters: before you risk a single rupee, you need a way to decide if a trade is even worth taking — not after you see how it turned out, but before. Risk-reward ratio is that tool.

It is just two rupee amounts compared to each other. Fix three prices before you enter: the entry price (where you get in), the stop-loss (where you exit if the trade goes against you), and the target price (where you exit if it goes your way). Your potential loss is entry minus stop-loss. Your potential gain is target minus entry. Divide gain by loss, and you have your risk-reward ratio.

Stop asking "did this trade win?" and start asking "did I decide the ratio correctly, before I entered?"

A ratio of 1:3 means you're risking ₹1 to make ₹3. That's favourable — it means even if you're wrong on some trades, the ones you win can more than pay for the ones you lose, over many trades.

But notice what the ratio does not tell you: it says nothing about whether this particular trade will win. It only measures the size of the bet — how much is at stake against how much could be gained. Winning or losing this one trade is a separate question, decided by the market, not by your division.

That's the real shift here: stop asking "did this trade win?" and start asking "did I decide the ratio correctly, before I entered?" A trade can be measured perfectly and still lose — that doesn't make the measuring wrong. What would make it wrong is skipping the calculation, or doing it after you're already in the trade, when fear or hope can quietly bend the numbers to match whatever you feel like doing.

Ananya is watching a stock trading at ₹500. Before she places any order, she writes down three numbers on a sticky note stuck to her monitor: Entry ₹500, Stop-loss ₹480, Target ₹560.

She does the maths right there, before touching the buy button. Potential loss: ₹500 − ₹480 = ₹20 per share. Potential gain: ₹560 − ₹500 = ₹60 per share. She divides: ₹60 ÷ ₹20 = 3. A 1:3 ratio — for every ₹1 she's risking, ₹3 stands to be gained.

She says it out loud, the way she's trained herself to: "I'm risking ₹20 to make ₹60. That's 1:3." Only then does she place the order. The ratio didn't tell her the trade would win — it told her the bet was worth taking if she was disciplined about the stop-loss. What happens next is a separate story.

Point: The risk-reward ratio is a simple division of two fixed rupee distances from the entry price, decided before the trade — and a correctly calculated favourable ratio can still end in a loss without the calculation or decision being wrong.

Follow that same ₹500 trade forward. The trader fixed entry at ₹500, stop-loss at ₹480, target at ₹560 — a clean 1:3 ratio, decided before entering. Then the stock turns the wrong way. It falls to ₹480, the stop-loss triggers, and the trade closes at a ₹20-per-share loss.

Nothing about the ratio was wrong. ₹60 potential gain against ₹20 potential risk was still a true, favourable comparison the moment it was calculated. The ratio never claimed this specific trade would win — it only described the shape of the bet: how much was at stake versus how much could be gained. The market simply moved against it. A well-measured bet and a losing outcome sat side by side, and both were true at once. That is the entire point of judging process separately from outcome — a single loss, even after correct maths, is not evidence that the maths or the decision was flawed.

• Believing a favourable ratio (like 1:3) means the trade is likely to win or is basically safe. — The word 'favourable' sounds like a probability, and it echoes gambling odds, so it's easy to mistake a size comparison for a win-chance score. Fix: Remind yourself the ratio only compares rupee amounts — how much you stand to gain versus lose. It says nothing about the odds of winning this specific trade.
• Concluding that a good-ratio trade which lost money means the calculation or the decision was wrong. — We naturally judge decisions by how painful the outcome felt, and a loss feels like proof of a mistake. Fix: Judge the decision by whether the ratio was calculated correctly and fixed before entry — not by whether this one trade happened to win or lose.
• Calculating risk-reward after already entering the trade, or adjusting it once the price starts moving. — It feels like planning, but once you're in the trade, emotion — hope or fear — quietly bends the numbers to justify staying in or getting out. Fix: Fix entry, stop-loss, and target before placing the order, and don't recalculate mid-trade to match how you feel.
• Treating the risk-reward formula as complicated trader jargon requiring advanced maths. — Unfamiliar terms like 'entry,' 'stop-loss,' and 'target' sound technical even though the maths itself is simple division. Fix: Remember it's just two rupee distances from the entry price divided by each other — gain ÷ loss — something anyone can do with subtraction and division.

• Risk-reward ratio = potential rupee gain ÷ potential rupee loss, both measured from the entry price.
• A favourable ratio (like 1:3) changes whether a bet is worth taking — it does not change whether this specific trade will win.
• Entry, stop-loss, and target must be fixed before you enter the trade, or the calculation isn't protecting you.
• A trade can be measured correctly and still lose — that doesn't mean the decision was wrong.
• Judge your trading by whether you planned the ratio in advance, not by how any single trade turned out.

Q1. What is the correct formula for the risk-reward ratio of a trade?

• Potential gain (in rupees) ÷ Potential loss (in rupees)
• Entry price ÷ Target price
• Potential loss (in rupees) ÷ Potential gain (in rupees)
• Target price minus stop-loss price Answer: Potential gain (in rupees) ÷ Potential loss (in rupees) — Risk-reward ratio is calculated as potential gain divided by potential loss, with both measured in rupees from the entry price.

Q2. A trader calculates a 1:3 risk-reward ratio before entering a trade, but the trade ends up hitting the stop-loss and losing money. What does this most likely mean?

• The trader made a calculation mistake somewhere
• The ratio and the decision were fine — the market simply moved against the trade
• A 1:3 ratio was too risky to ever consider taking
• The trader should have recalculated the ratio after entering Answer: The ratio and the decision were fine — the market simply moved against the trade — A favourable ratio describes the shape of a bet, not a guarantee of winning. A well-measured trade can still lose without the calculation or decision being wrong.

Q3. True or False: A favourable risk-reward ratio, like 1:3, means the trade is likely to win. Answer: False — The ratio only compares how much you stand to gain versus lose in rupees — it says nothing about the probability of this specific trade winning.

Q4. A trader plans a trade with an entry price of ₹200, a stop-loss at ₹190, and a target at ₹230. What is the risk-reward ratio? Answer: 1:3 (₹30 potential gain ÷ ₹10 potential loss = 3) — Potential loss = ₹200 − ₹190 = ₹10. Potential gain = ₹230 − ₹200 = ₹30. Ratio = ₹30 ÷ ₹10 = 3, or 1:3.

Q5. A trader is already in a losing trade and recalculates the risk-reward using today's price, concluding: "The numbers still look okay, I'll stay in." Is recalculating risk-reward mid-trade a sound way to decide? Reveal: Weak: yes, if the new numbers look okay, staying is fine. Strong: risk-reward calculated after already being in a trade is easily bent by hope or fear to justify whatever the trader already wants to do — it needs to be fixed before entry, not recalculated under the pressure of an open position.
