Understanding Trading House and IsFirstBarofSession

[timmbbo]

Hello there, I'm having difficulty understanding what hours each value in a chart's TimeFrame -> TradingHours represents, and it's relationship to IsFirstBarofSession.

I'm trading the NQ series, which closes down from 5-6 PM EST. It was my understanding that IsFirstBarofSession would be true after the marketplace opens after 6 PM EST. However, I see that IsFirstBarofSession is true during multiple points during the day, such as 11 PM EST or 7 AM EST. Ideally, I want IsFirstBarofSession to return True only within the first hour or so after the market opens. This leads me to a couple of questions:

- Is my understanding of IsFirstBarofSession accurate? That it should return true only at the start of a session, and not at multiple times over the course of a day?
- How do I learn what the exact hours are for each option under TimeFrame -> TradingHours: <Use Instrument Settings>, CBOE US Futures Index ETH, CFD AEX, and others?
- Can I configure my own custom TradingHours template?

As always, thanks for your support.

Hello timmbbo,

Yes, I would expect Bars.IsFirstBarofSession to be true only on the first bar of a session for the bar series.

Do you have multiple series added to the script with AddDataSeries()?
If so, are you checking the BarsInProgress to be 0?

You can view the trading hours for a TradingHours template in the Tools > Trading Hours window.
