How to determine if there is never a FirstBarInSession

[adamus]

I have a simple indicator which writes the bar numbers onto the chart.

There are already other indicators out there but I wanted to implement an extra piece of functionality - what I'm saying is that the other indicators don't do what I need and also don't suffer my current problem.

The current problem stems from how I restart the numbering on sessions - the following code snippet comes from the Plot() method, hence the Bars.Get()

if (Bars.Get(x).FirstBarOfSession)
{
    sessionBar = baseBar;
}
else
{
    sessionBar++;
}

and I use 'baseBar' as a user parameter to let me swap between starting numbering on 0 or on 1.

This is fine until I change the interval to Daily. Then there is no FirstBarOfSession.

Without writing a big function to check which Period and Interval is in force, is there another way to check whether there is never a FirstBarOfSession = true?

Hi adamus, only idea I would have as well is going over the BarsPeriod your code would see, generating bars not with a session concept underlying you would only have to deal with daily and higher.

OK I see. The other reason why I didn't do a function based on BarsPeriod is because there are others using this indie who use other Bar types of which I have very limited knowledge. I would have to rely on those users to tell me what they expect.

I have tested Bars.Get(idx).FirstBarOfSession on the plot method, and it always worked for intraday charts. For daily, weekly and monthly bars, there is no first bar of session. All you need to do is to check whether the current chart is an intraday chart or not:

bool existsFirstBarOfSession;

if (Bars.BarsType.IsIntraday)
     existsFirstBarOfSession = true;
else
     existsFirstBarOfSession = false;

OK, I'll put that in. It makes sense, being independent of BarType. Thanks v much.
