Updated Turtles

This script has been updated to prevent double orders (short/long) from occurring and modifying backtests results.

This is an update to the script that was written a few years ago to prevent double longs/shorts from occurring and skewin backtesting results. Check out the updated indicator here and let me know what you think.

I also added:

- date range inputs if you want to do some backtesting on a particular set of dates.
- the ability to toggle shorting

Versionshinweise:

Versionshinweise:
