How compounding works in trading
If you risk a fixed percentage of your current balance, your position size grows as the account grows. Each win is a little bigger than the last, and each loss a little smaller. Over hundreds of trades that adds up.
At 1% risk and +0.35R expectancy, the average trade adds 0.35% to the account. Twenty trades a month compounds to about 7% a month, before costs.
Why this is a best case
The planner assumes you hit your average results every month. Real trading doesn't work like that. Losing months, drawdowns and changes in market conditions all happen, and the order of wins and losses matters: a 30% drawdown needs a 43% gain to recover. Use this as a picture of what consistent execution is worth, not a forecast.
Small edges, big differences
Try moving the win rate by 5 points or the R:R by 0.5. The end balance changes far more than you'd expect, which is why tracking your real numbers and fixing small leaks matters more than finding a new strategy.
Before increasing risk to grow faster, check your risk of ruin. Compounding only works if the account survives long enough.
