Seems not to be a hard point, smile ... But i am really confused about my function. My goal is: I want to have a bool function that give back true if a new bar is opened. During initialisation / starting an EA first Tick will be nothing, so 1970.01.01 with value 0 should happen and be ignored. I really want to wait until the first complete new bar is opened. //+------------------------------------------------------------------+ //| IsNewBar //+------------------------------------------------------------------+ bool IsNewBar(ENUM_TIMEFRAMES m_timeframe){ static datetime lastbar; datetime currentbar = (datetime)SeriesInfoInteger(_Symbol,m_timeframe,SERIES_LASTBAR_DATE); if(lastbar != currentbar){ lastbar = currentbar; // if lastbar is 1970.01.01 (=value 0) ... This will happen during start an EA in the middle of a bar. if(lastbar != 0){ Print("true"); return true; }else{ Print("false"); return false; } } return false; } This is my testing code to activate the function: //+------------------------------------------------------------------+ //| Expert tick function | //+------------------------------------------------------------------+ void OnTick(){ if(IsNewBar(PERIOD_M1)==true){ Print("x"); } } It seems like completely ignored the first Tick 1970.01.01 thing. I did not figure out where my problem is. Please help! Thank you

I do: //Global: datetime newBarTime; //onInit: newBarTime = iTime(0,0,0) + Periodseconds(); //on the run if(TimeCurrent() >= newBarTime){ newBarTime = iTime(0,0,0) + Periodseconds(); return true; }

I found the problem of my original code. If anyone is interesting in, here is the working function: bool IsNewBar(ENUM_TIMEFRAMES m_timeframe){ static datetime lastbar; datetime currentbar = (datetime)SeriesInfoInteger(_Symbol,m_timeframe,SERIES_LASTBAR_DATE); if(lastbar != currentbar){ if(lastbar == 0){ lastbar = currentbar; return false; }else{ lastbar = currentbar; return true; } } return false; }
