@deltatrendtrading: When backtesting any strategy, manual or programmatic, it is critically important that you have a grasp on how confident you can be in your performance statistics. It’s very easy to perform a small back test of, say, under 100 trades with sizable variability in returns, drawdown, run-up, etc., and derive metrics from them that look favorable. If you don’t scrutinize those metrics and understand how confident you can be in their accuracy, then your backtest has little utility in the first place, and does not tell you much about how the future might play out. #quant #quanttrading #quantfinance #trading
