does the marketplace really understand anything about timeframes? i dont think so. the market only understands what the price is right now.

{quote} Hi, thank you very much for sharing this knowledge for MQ4. May I know if you have any ideas how to do multipair and multi timeframe on MT5? I tried similar method as yours for MT5, but creating the icustom handlers in the onInit increases my CPU usage to more than 90%. int OnInit() { if (UseDefaultPairs == true) ArrayCopy(TradePairs,DefaultPairs); else StringSplit(OwnPairs,',',TradePairs); if (ArraySize(TradePairs) <= 0) { Print("No pairs to trade"); return(INIT_FAILED); } ArrayResize(iCustomHandle_H1,ArraySize(TradePairs)); for(int i=0;...

{quote} Hi, I managed to solve the problem already. The issue is not with this iCustom Handler, it's the custom indicator that it is calling which is more resource intensive. Calling another custom indicator does not produce this problem.

qqe scanner example..... was sure i had posted this but can't find it on anywhere on any forum now...... maybe it was a dream..... part deals with a question about allowing users to select their timeframes.... in the video i show mladen's unique method first..... followed by mine..... my method is simple..... mladens method is stable.... or put another way, a 1 handle 1 tire wheel barrow might be simple but a 2 handle 2 tire wheel barrow is far more stable.....h //------ https://www.youtube.com/watch?v=1PEo-YkCD7U {file} {file}

{quote}So does that mean there is nothing to show at the moment hence no result? If yes then how can I keep it running in the background so that it gives me the alerts as soon as there is a qqe cross on any pair on any timeframe?

one should be able to specify the level from which trailing occurs and the level at which the trailing buy/sell stops should terminate if not triggered. Do you, perchance, have such a script/ea to share?

{quote} A bit late reply, but ... Don't use iCustom() or built in indicators (and I mean it) That means you have to change all in the code but then you can get acceptable results (like the example : average calculation time for those things bellow - and alma is not a very "simple" indicator - is 10-15 milliseconds for the time frames and symbols used by it). That would be 207 instances of alma (or any other indicator as a matter of fact) : trying to do that the "classical" way will just result in the issues you are having {image}
