We write down every backtest assumption,
including our own limitations

Institutions won't ask "how much return" — they'll ask "how does your backtest handle spreads, slippage, overnight interest, leverage and volume".These cost parametersRead directly from a real backtest engine instance——If the engine changes a number, the page will automatically change accordingly. There is no room for "good-looking copywriting and another set of engines".The last section lists our known limitations — platforms that hide assumptions don’t deserve “honest”.
