# Cumulative RSI This strategy was taken from chapter 9 of [*Short Term Trading Strategies That Work*](https://moshferatu.dev/moshferatu/short-term-trading-strategies-that-work) (2008) by Larry Connors. It is based on the [Cumulative RSI indicator](https://moshferatu.dev/moshferatu/ninjatrader/src/branch/main/indicators/cumulative-rsi) described in the book. ## Rules 1. The asset (e.g., SPY) is above its 200-day moving average. 2. If the 2-day cumulative 3-period RSI is below 45 (or 35, etc.), enter a long position. 3. Exit the position when the 2-period RSI is above 65. ---
