Strategy Bars Required Question

[stantenlee]

Not fully sure I follow - you should have a complete chart including the overnight action when setting your chart session times to 24hrs display.

You could use FirstBarOfSession (http://www.ninjatrader-support.com/H...OfSession.html) in NinjaScript and count your elapsed bars since it returned true.

Or you could add a time filter to your strategy, you could set it for example to trade only from 9:45 - 15:45 to let the market settle when the opening orders come in...

See this reference sample here for details - http://www.ninjatrader-support2.com/...ead.php?t=3226

How about if I want minimum 20 bars required to trade for each daily new session? How to set it by using the firstbarofsession? Any code example or sample for this?

Hi stantenlee, thanks for posting. If a topic is greater than 1 year old, please start a new topic and reference the link to the related topic:

To wait for 20 bars after the session you need a counter in the strategy that will count up to 20 since FirstBarOfSession is true. Counters are only possible in unlocked scripts, so you will need to write this in C# rather than using the builder. The C# logic would look like this :

Hi Chris,

I tried but not work as attached. What is my mistake?

Hi stantenlee, thanks for the follow up.

In NinjaTrader 8 it is "Bars.IsFirstBarOfSession" changing that should fix it.

Kind regards,
