# 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 2-period RSI is below 35, enter a long position. 3. Exit the position when the 2-period RSI is above 65. An alternate set of rules is provided in chapter 12 as follows (differences bolded): 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**, enter a long position. 3. Exit the position when the 2-period RSI is above 65. ## Parameters **Cumulative RSI Period**: The period to use in the RSI calculation.
