Evaluating Trade Frequency
Low Frequency (Under 30 Trades)
Strategies with very few trades (like long-term rotational investing) incur minimal slippage and broker fees. However, if a backtest only triggers 12 trades over 5 years, the sample size is statistically insignificant. The results might be pure luck.
High Frequency (1,000+ Trades)
High-frequency systems provide excellent statistical confidence in their win rates and profit factors. However, they are highly sensitive to real-world friction. If slippage or taxes eat just 0.1% per trade, a high-frequency system can easily turn from profitable to negative.
