1Not financial advice
Peirama does not provide financial, investment, trading, tax, or legal advice. It is a tool for testing and studying trading strategies against historical data. Any verdict, statistic, chart, or generated strategy is information for research and education only, and must not be treated as advice or as a personal recommendation. We are not a licensed financial adviser, broker, or portfolio manager.
2Backtests are simulations, not predictions
A backtest shows how a strategy would have behaved on past data under a set of assumptions. It does not predict the future. Markets change, and a strategy that performed well in a simulation can lose money in live trading. Past performance — real or simulated — does not guarantee future results.
3What our tests can and cannot tell you
Peirama's validation battery is designed to catch common ways backtests mislead — overfitting, look-ahead bias, and results indistinguishable from luck. This makes a passing result more trustworthy than a raw backtest, but it is still not a guarantee:
- A passing verdict means a strategy survived our tests on the data provided. It is not a promise of profit and not a signal to trade.
- A failing verdict means the strategy did not survive those tests. It is not a guarantee the underlying idea is worthless in all conditions.
- Our tests cannot account for everything: future regime changes, liquidity, real execution, counterparty risk, or your own behaviour.
4Data limitations
Results depend on historical market data that may contain errors, gaps, or biases (including survivorship bias). Simulated fills, fees, and slippage are approximations. Real trading costs and conditions will differ, sometimes materially.
5Your responsibility
Any decision to trade, invest, or deploy capital based on anything you learn from Peirama is your decision alone. You should do your own research and, where appropriate, consult a licensed professional who can consider your personal circumstances. Only risk capital you can afford to lose.
6No liability for your trading results
To the maximum extent permitted by law, Peirama accepts no responsibility for any trading or investment losses, or any other loss or damage, arising from your use of the Service or reliance on its output. This disclaimer forms part of, and should be read together with, our Terms of Service.
