Good afternoon to all. After optimizing an EA, we often have to nerd out-of-sample more than a dozen sets of parameters suggested by the optimizer. I have an idea of optimizing Expert Advisors outside the sample. Suppose we "charged" the Expert Advisor with optimization by a number of parameters

Hi Guys, ATR calculated for a shift bigger than about 8500 bars always results in zero. Do you have any ideas why and how to solve it? wrote this code to check it: int start() { int i; while (i < 10000 ) { double ATR = iATR ( Symbol (), 60 , 10 ,i); if (ATR == 0 ) { Alert ( Symbol (), " "

I know alerts are a popular question and I have read how to do an alert and faithfully followed an example that seemed a good fit for what I seek to do with an indicator I am working on.
