Method: identifying flags and pennants
First, find a strong prior trend on the daily chart. A flag is a small rectangle sloping against the trend. A pennant is a small symmetrical triangle. Both need lower volume during consolidation. The breakout must happen with a volume spike. Enter on the close above the high or below the low. Set a stop at the opposite side of the pattern. Take profit at 1.5 times the pattern height.

Tips for using backtest data in prop firm challenges
- Use daily charts to avoid noise. - Set stop loss at the consolidation low or high. - Take profit at 1.5x risk for consistency. - Only trade stocks with average volume above 1 million. - Avoid patterns that form in low volatility markets. These tips help you pass the consistency rules of prop firms.

Common mistakes in backtesting patterns
Look‑ahead bias is a big one. Do not use future data to set entries. Overfitting happens when you optimize too many parameters. Small sample sizes give unreliable results. Always test at least 200 trades. Another mistake is ignoring transaction costs. Include slippage and commissions to get realistic numbers.
