4. Think in odds, not certainty

7 min readUpdated 08 Oct 2026

Here is the hardest truth for new traders: you will be wrong often. Even with a great setup.

That is not a failure of your analysis. It is how probabilities work.

The cricket captain and the toss

A captain who wins the toss chooses to bat on a flat pitch – the right decision based on conditions. Then rain comes, the pitch changes, and his team collapses. Was the decision wrong? No. The decision was good; the outcome was bad.

Trading is full of good decisions with bad outcomes, and bad decisions with lucky outcomes. Judge yourself on the decision, not on one result.

4.1 What is an edge?

An edge is a situation where, over many repetitions, the results are in your favour. It does not mean this trade will win. It means that if you take this kind of trade 100 times, with the same risk rules, you are likely to end up positive.

Two things decide your edge:

  1. Win rate – how often you win.
  2. Reward-to-risk – how much you make when right, compared to how much you lose when wrong.

You can have a great edge with a 40% win rate if your winners are twice your losers. You can lose money with a 70% win rate if your losers are huge.

4.2 See it for yourself

Run it several times. Notice:

  • Even with a positive edge, there are losing streaks of 5, 6, 8 trades. They are normal.
  • Different runs of the same edge give very different paths. Luck is real in the short term.
  • Over 100 trades, the edge shows up.

4.3 What this means for you

  • Never risk too much on one trade. A losing streak must not wipe you out (remember the 1% rule).
  • Don’t change your method after 3 losses. Judge a method after 30–50 trades.
  • Don’t get overconfident after 3 wins. It may just be luck.
  • Every trade is just one of the next hundred.
From Karan

Jab aap odds mein sochne lagte ho, ek loss se dukh nahi hota, aur ek win se ghamand nahi aata. This calm mind is the real edge in trading. Market ka koi bhi chart pattern iske bina kaam nahi karta.

Quick check
You took a well-planned trade at support with a stop-loss, and it lost. What is the right conclusion?

Single outcomes are random. Edges show up over many trades.

Quick check
Which trader has the better edge? A: wins 70%, average win ₹1,000, average loss ₹3,000. B: wins 40%, average win ₹3,000, average loss ₹1,000.

A: 0.7×1,000 − 0.3×3,000 = −₹200 per trade. B: 0.4×3,000 − 0.6×1,000 = +₹600 per trade.

Key takeaways from this chapter
  • Every setup can fail. Think in probabilities.
  • Edge = win rate combined with reward-to-risk, over many trades.
  • Losing streaks are normal even with a good edge. Size your risk so you survive them.
  • Judge decisions, not single outcomes.
  • Ek line mein: Ek trade se kuch tay nahi hota – sau trades mein edge dikhta hai, isliye har loss pe ghabrao mat.
