Most trading ideas look brilliant until you test them. Free backtesting lets you find out cheaply, before the market charges you full price for the lesson.
I have watched traders fall in love with a strategy after three good weeks. Then a different kind of market arrives and the edge vanishes. A proper test over many conditions would have warned them.
A backtest is only as honest as its assumptions. Fees, slippage, survivorship and the urge to tweak until the curve looks pretty can all fool you. The goal is not a beautiful equity line. The goal is a result you would still believe after a bad month.
This finder asks five questions about what you want to test, what stopped you last time, how you want to build the test, your budget and how rigorous the result needs to be. Your answers become criteria, and every tool is scored against them in the open.
You get three matches with the reasons spelled out. Start with free backtesting to learn what your idea really does, and only pay when your tests outgrow it. A strategy that cannot survive an honest test is a strategy that has saved you money.
