OnBarUpdate

[SystemTrading]

The following code only executes once when I initialize the strategy. Afterwards, I get nothing. I would like to see the code Print "OBU" on each tick. What would be the reason this isn't working?

Any error messages in the Log tab?

Provided that you have enough bars on your chart when you are running the strategy (make sure Min bars requires is set to 20 --> You could try setting to 1 to check) it will print. to the Output window.

I am getting the following error...

"Error on calling 'OnBarUpdate' method for strategy 'MyStrategy': Object reference not set to an instance of an object."

Thanks, that would explain why you don't see anything. Somewhere in your strategy you have a logic error that causes this exception which terminates the strategy.

Here is a a tip we wrote up to help guide you to resolution.
