What is Expectancy? (memecoin term explained)

Expectancy is the average profit or loss you can expect per trade over many trades, combining your win rate and the size of wins vs. losses.

Definition: Expectancy

Expectancy is the average profit or loss you can expect per trade over many trades, combining your win rate and the size of wins vs. losses.

Key idea — Expectancy, not win rate, is what determines whether a strategy makes money. A low win rate with big winners can crush a high win rate with tiny ones.

Key things to know about expectancy

Formula: (win% × avg win) − (loss% × avg loss).
Positive expectancy = profitable over many trades.
Costs (fees, slippage, spread) directly reduce expectancy.
On microcaps, costs can flip a "good" setup negative.
Sample size matters — short streaks lie about your true edge.

A worked example

A 35% win rate with 5x average winners and 1x average losers has strongly positive expectancy, despite losing most trades.

What to watch out for

Watch out — High win rate feels good but means nothing if your losses dwarf your wins. Judge a strategy by expectancy, after costs.
