Expectancy in trading<\/a> is the average amount you can expect to gain or lose per trade over a series of trades, calculated from your win rate and the average size of your wins and losses. A positive expectancy means the strategy is profitable over the long run; a negative expectancy means you will lose money over time no matter how disciplined your execution.<\/p>\n

What Is Expectancy?<\/h2>\n

Expectancy translates your trading strategy’s historical performance into a single number that tells you if the strategy makes or loses money per trade, on average.<\/p>\n

**Formula:**
\nExpectancy = (Win Rate x Average Win) – (Loss Rate x Average Loss)<\/p>\n

**Example:**
\nWin rate: 45%
\nAverage winning trade: Rs 3,000
\nLoss rate: 55%
\nAverage losing trade: Rs 1,200
\nExpectancy = (0.45 x Rs 3,000) – (0.55 x Rs 1,200)
\n= Rs 1,350 – Rs 660
\n= Rs 690 per trade<\/p>\n

This means that on average, each trade earns Rs 690. Over 100 trades, the expected profit is Rs 69,000.<\/p>\n

Why Expectancy Matters More Than Win Rate<\/h2>\n

Many traders obse<\/a>ss over their win rate. But the real measure of a strategy is expectancy. A strategy with a 35% win rate and a 1:5 risk-reward can have much higher expectancy than a 65% win rate strategy where winners are barely larger than losers.<\/p>\n

Positive vs Negative Expectancy<\/h2>\n

– **Positive expectancy**: the strategy will be profitable over a large number of trades
\n– **Negative expectancy**: the strategy will lose money over time no matter how good the risk management<\/a>
\n– **Zero expectancy**: breaks even before costs; transaction costs make it negative<\/p>\n

Calculating Your Expectancy from a Trade Journal<\/a><\/h2>\n

1. Review the last 100 trades from your journal
\n2. Calculate: total winning trades \/ 100 = win rate
\n3. Calculate: sum of all wins \/ number of wins = average win
\n4. Calculate: sum of all losses \/ number of losses = average loss
\n5. Apply the formula<\/p>\n

Practical Example<\/h2>\n

Sanjay has traded 200 futures contracts<\/a> over 6 months. 80 trades were winners averaging Rs 4,500 each. 120 trades were losers averaging Rs 2,000 each. Win rate: 40%. Expectancy = (0.40 x Rs 4,500) – (0.60 x Rs 2,000) = Rs 1,800 – Rs 1,200 = Rs 600 per trade. His strategy has a positive expectancy of Rs 600 per trade. Over 200 trades, total expected profit: Rs 1.2 lakh.<\/p>\n

Key Takeaways<\/h2>\n

– Expectancy is the average profit or loss per trade based on win rate and average win\/loss size
\n– Positive expectancy means the strategy is profitable over many trades
\n– A 40% win rate strategy with 1:3 risk-reward has better expectancy than a 60% win rate with 1:1 risk-reward
\n– Calculate expectancy from at least 100 trades in your trading journal for statistical significance
\n– Expectancy is the single most important metric for evaluating a trading strategy’s effectiveness<\/p>\n","protected":false},"excerpt":{"rendered":"
