Consistent actions, not consistent profits
Markets don't pay the same every week, so chasing a smooth equity curve week to week leads to forcing trades. Consistency means your inputs stay the same: which setups you take, how much you risk, when you trade and how you manage trades. Results are allowed to vary.
Why consistency matters: expectancy
A strategy's edge only shows over many trades. Expectancy tells you what one trade is worth on average, measured in R, where 1R is the amount you risk.
Expectancy = (Win rate × Average win) − (Loss rate × Average loss)
Say you win 45% of trades, your average win is 2R and your average loss is 1R. Expectancy is 0.45 × 2 − 0.55 × 1 = 0.35R per trade. Over 100 trades that is about 35R. If 1R is $50, that's around $1,750, even though you lost more trades than you won.
That number only holds if every trade risks the same R and follows the same rules. Doubling size after a loss, or skipping setups after a bad day, changes the maths and usually for the worse.
The four things to keep the same
- Risk per trade: the same percentage, every trade, sized with a calculator.
- Setups: only the ones you have written down and tested.
- Session: trade the same hours, for example the London and New York overlap.
- Management: the same rules for moving stops and taking profit.
Consistency when results swing
Even a strategy with positive expectancy will have bad weeks. With a 45% win rate, a streak of six or seven losses is normal across a couple of hundred trades. The consistent trader takes the eighth trade at the same size, because the maths depends on it.
Prop firm consistency rules
Some prop firms have a written consistency rule, for example that no single day may make up more than a set share of your total profit. The rule exists to spot traders who pass with one oversized bet. If your risk and trade count stay steady, you rarely come close to it. Read your firm's exact wording, since it differs between firms.
How to measure your consistency
- Did every trade risk within 0.1% of your planned risk?
- How many trades were outside your written setups?
- How many trades were taken outside your session?
- What share of trades followed your management rules?
Track these in your trading journal for a month. Improving these numbers improves results more reliably than hunting for a new strategy.
