Why Do a Few Trades Make All My Profit?

It is common, especially for strategies that cut losses and let winners run. It becomes a concern when it is combined with a low win rate and few trades, because then the result may rest on chance. The numbers in the report let you judge how much weight to give it.

Look at what those trades have in common: a size larger than usual, a stop that was not honored, a time of day, or an instrument. The pattern in the large losses is usually more useful than the average loss.

A tenth is large enough to be stable and small enough to show concentration. Using a fixed share of your trades, not a fixed count, keeps the comparison fair whether you have 30 trades or 3,000.

A CSV where each row is one finished trade with its result: your exchange's closed positions or profit-and-loss history. It needs a close time and a result, or entry price, exit price, quantity and side. A list of individual order fills is not enough, because fills cannot be paired into trades without guessing.

The file is read in memory and is not saved. Only the result of the analysis is kept: for 7 days if you do not sign in, or until you delete it if you save it to your account. The analyzer never asks for exchange passwords or API keys.
