Re: [amibroker] first/last 1-minute bar of each day

This would give you the changeover at midnight per your database settingsIf you need to use times during the day to define sessions then just use timenumthis will give session times for 10am to 4pm, just adjust the times and < <= > >= conditions to suit how you have the bar period times shown, ie shows at start or end of period per your preferences
Start = ref(timenum(),-1)<100000 and timenum()>=100000;Finish = timenum()<=160000 and ref(timenum(),1)>160000;-- CheersGrahamAB-Write >< Professional AFL Writing Service

if the data base is 24hr data?

  hello group,
   
  i want to simulate/backtest a 
  system which closes all positions via MOC. how do i reference the LAST 
  1-minute bar for each individual day (sometimes my DB has 15:59, sometimes 
  15:58, sometimes 16:00 etc.)
  and how would i code the FIRST 
  1-minute bar for the day?
   
  thanks,
