# TRIN Thrusts

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.

## Parameters

**Long-Term Trend Period**: The period of the long-term trend as measured using a simple moving average. (Default: 200)

**Percent Below**: The percent below the previous TRIN value required to enter a trade. (Default: 40.0, differs from the book)

**Days to Exit**: The number of days to wait before exiting any open trade. (Default: 2)
