How do I fix OnBarUpdate Error?

[relogical]

I am running a muti time frame strategy with 20 Range and the secondary time frame and 2 Range as primary. Every time I start the strategy I get an error that says I am accessing an index with a value that is invalid... Please show me a way to fix this. Thank you

Hello relogical,

Thanks for your post.

In an MTF environment it is easy to miss an index reference. Without specific error messages or code to review, the best advise I can provide is to review the tips we have in the guide for multi-time frame: http://www.ninjatrader.com/support/h...nstruments.htm The guide provides specific requirements for MTF scripting consideration of the various indexes.

Please let me know if I can be of further assistance.

Make a check for CurrentBars, and return if said check is not satisfied.

In OnBarUpdate(), please include the following statements at the very first lines:

if (CurrentBars[0] < X) return; // ensure your primary series has enough bars
if (CurrentBars[1] < Y) return; // ensure your secondary series has enough bars

Your assignment is to determine X and Y, based on your specific indicator programming.

Thanks.
