[amibroker] Re: Intraday Bar Counter

Trading Reference Links

I came up with the following indicator...hopefully some of you will 
enjoy this more flexible version.

paolo


function IntradayBarsCounter (MyClosingTime)
{
//MyClosingTime is the closing time of your market in TimeNum format
//i.e. 221500 for CME e-miniS&P for instance - GMT+1
//this allows to get the correct number of bars within current session
//even for electronic markets opening overnight

MyClosingtime = DateTimeConvert( 2, DateNum(), MyClosingTime);
numbars = 1 + Ref(BarsSince(DateTime() == MyClosingTime), -1);
return numBars;
}

Plot(IntradayBarsCounter(221500), "Bars", colorWhite, 
styleLine|styleOwnScale);
