How to run strategy in Real Time

[lucktrader]

Hi,

I've developed a multiple instrument strategy that run fine from the strategy analyzer. However, when I tried to run it in real time from a chart or from the control center, nothing seems to be happening. I am outputting debugging information and it looks like the strategy never starts.

Thanks.

Check the log? Any errors?

Error in log

Yes,

I see an error in the log. The message is:

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

Then there is a logic flaw in your strategy, somewhere you are accessing a variable/property/method that does not hold an object.

Thanks. I am able to get it to run partially now. Is there a limit on the number of characters the output window can handle? The strategy seems to start from the beginning of time. If I limit it to one day, the strategy runs. Is there a way to enter and exit positions only when it is from the current time or later?

if (Historical) return;

Thanks. Do you have a suggestion on how to recognize if a strategy is being from from the strategy analyzer versus being run from a chart in real time?

If I have the historical statement in place, I can not backtest my strategy. I would hate to have two copies of the same strategy.

Create a bool property that you can set at run time to say whether or not it is a backtest or not.
