IsFirstBarOfSessionByIndex() returns true for different k bars

[i019945nj]

Hello,

Good morning at your side.

I want to count the # of times the market breaks the high or low hence use IsFirstBarOfSessionByIndex() in below piece of codes, which is called in OnBarUpdate(); but it turns out the function returns true at different candles, as in the attached picture. Shed some lights? Grateful.

Regards,
Steven Meng


protected int TodaysFirstBar() {

int barPointer;

for (barPointer= CurrentBar; barPointer > 0; barPointer--) {

if (Bars.IsFirstBarOfSessionByIndex(barPointer))

break;

}

return barPointer;

}

Hello Steven,

If you want the bar index of the first bar of the session use (CurrentBar - Bars.BarsSinceNewTradingDay).

https://ninjatrader.com/support/helpGuides/nt8/barssincenewtradingday.htm

If you want to know if the current bar is the first bar of the current session use Bars.IsFirstBarOfSession.

https://ninjatrader.com/support/helpGuides/nt8/isfirstbarofsession.htm

The Bars.IsFirstBarOfSessionByIndex() will provide true, if the absolute bar index supplied is the first bar of a session. (This could be the first bar of the current session, previous session, session prior, etc).

In your loop, the value will change to the absolute bar index of the new session, one a new session starts.
