Breakeven win rate

Tells you how often you must be right for a reward-to-risk ratio to break even. Use it when choosing targets, or judging a strategy.

Win rate on its own is meaningless. A strategy that wins thirty percent of the time can be excellent and one that wins seventy percent can be terrible. What decides it is the size of the wins relative to the losses. This card connects the two by asking the only question that matters: at this reward to risk, how often must I win simply to stand still?

The relationship is straightforward. At one to one you need to win more than half. At two to one the bar drops to about thirty three percent. At three to one it is twenty five. Each step up in reward lowers the required win rate, but with diminishing returns, and the trade off is that distant targets are hit less often. Reaching for a five to one target does not make a strategy better if only one trade in ten ever gets there.

Margin over breakeven is the number to watch. It is the gap between your actual win rate and the bar, and it is your edge stated in percentage points. A margin of one or two points is not really an edge, because it is well inside the error of a win rate estimated from a modest sample, and costs will consume it. A margin in double digits is a strategy with genuine room to survive slippage, commission and a period of underperformance.

The last row inverts the question. Given the win rate you actually achieve, what reward to risk would you need to break even? This is often the more useful direction, because your win rate is largely a property of your method and hard to change, while your targets are a choice you make on every trade. If your record says you win forty percent, you need better than 1.5 to 1 to break even, and anything you can do to widen targets or trail winners moves that ratio in your favour.

Remember the bar shown is for breaking even, not for making money. Costs sit on top of it. Add commission, spread and slippage and the real bar is a few points higher than the figure here, which is what the commission impact calculator quantifies.
