# TRIN Thrusts
2024-11-10 14:24:51 +00:00
This strategy was taken from chapter 3 of [*Connors on Advanced Trading Strategies* ](https://moshferatu.dev/moshferatu/connors-on-advanced-trading-strategies ) (1998).

## Rules
1. If the closing TRIN is 30% or more below the previous trading day's closing TRIN, enter a long trade (e.g., on SPY).
2. Exit the trade 2 trading days later.
I have also added a condition that the asset must be trading above its 200-day moving average that was not present in the book.
This implementation does not go short due to consistently negative returns.
