This article is about how to do that arithmetic yourself. It will not make you popular with anyone selling a strategy, because the honest answer is that a great many published records, including some with genuinely real trades in them, prove nothing.

How Many Trades Do You Need to Judge a Trading Strategy?

For a rough read on a win rate, a few hundred. For confidence that an edge is real rather than luck, closer to a thousand, and even then only if those trades span more than one market regime. Anything under about a hundred trades should be treated as an anecdote, not a result.

The reason is a formula you can run in a spreadsheet. The uncertainty around an observed win rate is roughly the square root of p times (1 minus p), divided by the number of trades, where p is the observed win rate. Multiply that by 1.96 and you have a 95% confidence interval: the range the true win rate plausibly sits in.

Run it on a record showing a 55% win rate and the result is sobering.

Read the first two rows again. A 50-trade record showing 55% wins is statistically indistinguishable from a coin flip. That is not a criticism of the trader. It is a statement about what fifty observations can support, and it applies identically to your own results.

What Does a 55% Win Rate Actually Tell You?

On its own, almost nothing, even with a thousand trades behind it. Win rate without average win and average loss is a number with no meaning, because a strategy winning 80% of the time can lose money steadily and one winning 35% of the time can compound beautifully.

Consider two records, both with 500 trades.

Strategy A wins 72% of the time. Average win 40 euros, average loss 130 euros. Expectancy per trade is 0.72 times 40, minus 0.28 times 130, which is 28.8 minus 36.4, a loss of 7.60 euros every trade. Over 500 trades that is 3,800 euros gone, with a win rate that looks superb on a marketing page.

Strategy B wins 38% of the time. Average win 210 euros, average loss 90 euros. Expectancy is 0.38 times 210, minus 0.62 times 90, which is 79.8 minus 55.8, a gain of 24 euros per trade. Over 500 trades, 12,000 euros, from a record that looks mediocre in a headline.

Strategy A is the shape produced by cutting winners early and letting losers run, and it is the most common losing pattern in retail trading. It is also the easiest to market, because the win rate is the number people screenshot. Always ask for average win, average loss and the number of trades together, or ask for expectancy in R, which folds all three into one figure. Risk and reward explains that ratio properly.

Why Does Time Matter More Than Trade Count?

Because markets change, and a strategy's edge is a claim about conditions that may no longer hold. A thousand trades taken inside eighteen months of one trending, low-rate, low-volatility environment tell you how the strategy behaves in that environment and nothing about any other.

This is why a high-frequency record can reach a thousand trades in six months and still be weak evidence, while a swing strategy with 300 trades across five years may be stronger evidence despite the smaller sample. You want the sample to cover regime changes: a rate-hiking cycle and a cutting cycle, a volatility spike and a grinding summer, at least one genuine crisis month.

Ask for the trade-by-trade history with dates, and look at what the record lived through rather than only what it totalled. A record starting in 2023 has not seen a real liquidity shock. A record that skips the months either side of a crisis has probably been curated.

The gap between a tidy backtest and what actually filled in the market is its own problem, and backtest versus live results covers where those numbers usually diverge.

Can a Losing Strategy Look Good for a Year?

Yes, easily, and this is the part of the maths that gets ignored because it is uncomfortable. If a thousand people each run a strategy with no edge at all, pure chance alone will hand roughly 25 of them a year that looks excellent, and a handful will look spectacular.

Those are the records that get marketed, because the other 975 quietly stop publishing. You are not seeing a sample of strategies. You are seeing the survivors of a selection process, which is why a leaderboard of top-performing accounts is one of the least informative documents in finance. The winners at the top of a copy-trading leaderboard are selected for having won, and that is true whether or not any edge exists anywhere in the population.

The practical defence is to ask for the things survivorship cannot fake. How many accounts or strategies did this provider run over the period, and where are the records of the ones that were discontinued? What is the full history of this specific account, from its first trade, not from a start date someone chose? Is the record verified by a third party that the provider cannot edit?

That last question is why verification matters more than the numbers themselves, and it is the standard TIC holds itself to: the Myfxbook record at /results is published in full, including the bad months, because a record the publisher can quietly trim is not a record. How to actually read one of those pages is covered in reading a Myfxbook track record.

Does Sample Size Change How You Read Drawdown?

Yes, and in the direction people least expect. The maximum drawdown in a track record is not a property of the strategy. It is the worst thing that happened to have occurred in the observation window, and the longer you watch, the worse that number gets.

A strategy observed for six months might show a 9% maximum drawdown. The same strategy, unchanged, observed for five years will very likely show something considerably worse, because there was more time for a bad run to happen. Treating the short-window figure as a ceiling is how investors end up shocked by a drawdown the strategy was always capable of producing.

A useful habit: whatever maximum drawdown a short record shows, assume the real capacity is meaningfully larger, and ask yourself whether you could sit through that without abandoning the position at the worst moment. What drawdown really means and drawdown, Sharpe and reading a track record go further into how those figures are computed and misread.

The same logic applies to Sharpe ratios. A Sharpe computed from twelve monthly returns has an enormous confidence interval around it, wide enough that a Sharpe of 1.8 over one year and a Sharpe of 0.6 over one year are not reliably different strategies. Sharpe becomes meaningful over years, not quarters.

What to Ask For Before You Trust Any Record

Five questions, in order, and a provider who cannot answer them has told you something.

None of this tells you a strategy will work. Statistics can only tell you whether the evidence is strong enough to be worth considering, and the honest answer for most marketed records is that it is not. Knowing which records to discard is most of the skill, and it is the same judgement covered in due diligence before trusting a trading provider.
