I can't get my head around CalculateOnBarClose

[Space123]

"When indicators or strategies are running on historical data, OnBarUpdate() is only called on the close of each historical bar even if this property is set to false. This is due to the fact that with a historical data set, only the OHLCVT of the bar is known and not each tick that made up the bar."

What I don't understand is, we know the open comes before the close. If I want to program:

if todays open is > than yesterdays close, go long on todays open, exit on todays close

is it the case that I simply cannot do this in Ninjatrader with daily bars? Can I use a different method?

Thanks for the clarification,

Ben

When you are backtesting or running historically you only have snapshot OHLC. Since you have the close, each moment you are evaluating a bar you are evaluating it at the close. That being the close, you cannot trade on the open of the bar because that bar is already closed. All trades need to go to the next bar as that is the next tradeable location.

No way around this without intrabar granularity: http://www.ninjatrader-support2.com/...ead.php?t=6652
