Renko Charts and "on bar update"

[benwinckelmans]

Good evening to you

Made a few progress in my "ninja scripts.

But I Wonder..

does the "on bar update method" work exacty de same way as it does with a time "based chart"

I'had the "strategy button" not accessible "light grey" quite a few times.

and I Wonder where I'm wrong

Thanks for your help

Hello Benoit,

How OnBarUpdate() will act will depend on what CalculateOnBarClose(COBC) is set to as it can vastly effect how your code functions. If COBC is true, then the strategy/indicator will be calculated at the close of each bar/beginning of a new bar so. If COBC is false, then it will act differently since it will be calculated on each tick. You may see the following link for more info on COBC.

If the Strategy button is greyed out then you may want to check the following items:

* NinjaTrader must be connected to real-time incoming data, note the Simulated Data Feed (for some instruments) and Market Replay Data may be used.
* You can not run Chart Trader on a chart while you have a running strategy applied to the chart (to disable right click inside chart, select Properties, and make sure Show chart trader is set to False)
For more information you may view the following link that goes over "Running a NinjaScript Strategy from a Chart".
