Why Do Fees Eat My Trading Profits?

It depends on your fee rate, your position sizes and how often you trade, which is why a general figure is not useful. Enter your own numbers into the trading fee calculator, or upload your history to see the fees your file actually records.

Maker orders usually pay a lower fee than taker orders because they add liquidity instead of removing it. Whether they suit your strategy depends on whether you can wait for your price. The fee calculator lets you compare the two rates.

Then fees cannot be analyzed from it, and the analyzer says so. Many exchange exports include a fee column; if yours does not, a separate fee statement or the transaction history may list them.

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.
