this is going to work ??

hey tram...... not sure exactly what your referring to.....

the idea behind trailing stop ea's does work..... the 5 minute chart picture below is from last night...... it's easy to visualize a trailing stop riding the psars or yellow 20 ma......

a trailing stop can trail many things like psar, moving averages, trendlines and such......

enivid has a psar trailing stop ea here.....

enivid has a moving average trailing stop here.....

atr trailing stop here.....


i'm just now learning mq5..... so some of my functions are at the beginner level..... will need to be improved.....

these functions eventually have the absolute minimum code required.....h

bare minimum trailing ma stoploss code for darwin ea....... appears to work for sells..... yellow ma is 20.......h

For the < brackets not to get garbled by the forum, it's necessary to insert them directly to the code box, like this:

#include <Trade\OrderInfo.mqh>
#include <Trade\Trade.mqh>
CTrade trade;

note to me...... verify on every instrument......

need to account for tick size..... this will set the psar, ma, and other type values dead on the closest price.....

otherwise considerable chance of invalid stops error......h

having premade symbol arrays was ok in typical forex and such because they never change...... that approach is a real pain with futures....... the preferred contract month changes and somewhat randomly........ editing the list gets real old real quick......

in futures, seems best to just arrange the market watch symbols in your preferred order..... slide them up or down...... you will memorize their location quickly......

then use the market watch as your symbol[array] list..........h

const int total = SymbolsTotal(true);
   for(int i = 0; i < total; ++i)
   {
  
      string sym = SymbolName(i,true);   
      
      Print(sym);
   }
