 As with most of the strategies from this book, they are meant to illustrate certain characteristics of the market rather than be traded directly.
 
+## Rules
+
+### 2-Period RSI Highs
+
+1. The asset (e.g., SPY) must be above its 200-day moving average.
+2. If the 2-period RSI closes above 85 (95 in the book), enter a long trade.
+3. Exit the trade after 5 trading days (~1 week).
+
+### 2-Period RSI Lows
+
+1. The asset (e.g., SPY) must be above its 200-day moving average.
+2. If the 2-period RSI closes below 15 (5 in the book), enter a long trade.
+3. Exit the trade after 5 trading days (~1 week).
+
+The 2-period RSI entry thresholds differ from the book as they led to improved backtest results.
+
+I also wanted to avoid overlap with the [2-Period RSI strategy](https://moshferatu.dev/moshferatu/ninjatrader/src/branch/main/strategies/2-period-rsi) from [Short Term Trading Strategies That Work](https://moshferatu.dev/moshferatu/short-term-trading-strategies-that-work).
