I'm a novice and trying to learn the language. I am a programmer and have been using EOD for about 4 years on and off. I've created a very simple indicator that gives me a boolean return. It only has the hammer() function. I wish to indicate in the tester that a buy happens when this is 1. So I place the formula in the buy - FML(mygreatFormula)=1 I wish to tell it when to sell - either in 4 days or after an increase of 10% from the purchase price whichever is more profitable. Can anyone guide me as to where to find this kind of information? Thanks... Jerry
