Hello esignal,

Thanks for opening the thread.

You can get the expiration month for an Instrument using the Expiry property. The DateTime object returned can then be used to calculate when your last week of trading for that month is.

As for detecting the last day of a trading week, you can access the TradingHours property of a Bars object to see detail on the Trading Hours Sessions so you can observe when the last day of the last session (last day of trading trading week) is.

TradingHours.Sessions - https://ninjatrader.com/support/help...s_sessions.htm

Please let me know if I can be of further assistance.

i print this code in my indicator

for (int i=0;i<5;i++)
{
Print("begin " + i + " " +Bars.TradingHours.Sessions[i].BeginDay);
Print("end " + i + " "+Bars.TradingHours.Sessions[i].EndDay);

}

Is finding the last trading day of the week not just checking if it is a Friday?

To find if a day is in the last week of the month, you just need to check if the month of the date is different from the month of the date 7 days hence.

if (Time[0].Month != Time[0].AddDays(7).Month)
{
//this is the last week of the month
}

Be sure that the Calculate property is correctly set for whatever it is that you want to do.

you say : Is finding the last trading day of the week not just checking if it is a Friday?

It's ok but if friday is Holiday it is not correct

should I use the default setting of holidays and since can be incorrect I'd rather use other

Hello esignal,

You can use TradingHours.Sessions.Count-1 to get the index for the last Trading Session (trading day.)

Print("LastSesh " + (TradingHours.Sessions.Count-1) + " " + Bars.TradingHours.Sessions[TradingHours.Sessions.Count -1].EndDay);

LastSesh 4 Friday

For detecting trading holidays in particular, I would suggest to access the Holidays property from TradingHours and checking the DateTime objects in the Holidays collection. Example code to print each holiday in the collection can be found in the Help Guide.

If there is any thing else I can do to assist, please let me know.
