How it is possible to define the All Time High as another Buy Condition?

How it is possible to define it as another Buy Condition, when I wanna say, that the stock should be not more than 10 percent under the All Time High?

[processingclouds]

It would be something like this :

Code: Select all

 
var float ATH= 0.0
var float under10 = na
ATH := math.max(high, ATH)
under10 := ATH * 0.90

isLong = yourCondition and close > under10

It works very well, thank you so much.
