Turtle minor and major trading signals – for AmiBroker – Use at your own risk

CAUTION: Turtles was originally designed to trade futures. Using it with stocks might pose many problems. Be sure to back test and optimize this with any stock you might use it with AND back test again.

NOTE: This is a rudimentary implementation as it does not include the following:

  • volatility share sizing
  • stops
  • Trade selection which only trades following a theoretical

Two default periods are used 20/10 for short term trading and 65/30 for long term trading. Try to optimize these values but be careful not curve fit. It must work across many stocks, etc. OR it is curve fitted.
