Error on calling "OnBarUpdate" method on bar 0

[Conceptzx]

I'm getting this error on a strategy I built. I have tried every conceivable way to resolve it from responses in the forum but it's still not working. Is it possible that it's just not reading the chart data for some reason, and not a simple conflict?

Everything compiles fine. I started with strategy builder to get a base code, then built everything out from there, I recently added order instructions and when I went to do a dry run with it, I get the error as I try to enable it.

Hello Conceptzx,

What is the full error message?

Ctrl + c to copy the error from the Log tab of the Control Center, Ctrl + v to paste in your reply.

If the full error is stating an index error, see the forum post below.

Strategy 'CXreversal': Error on calling 'OnBarUpdate' method on bar 2: Index was outside the bounds of the array.

is the NS output I get



if (BarsInProgress != 0)
return;

if (CurrentBars[0] < 2)
return;

is how I have it currently configured. Look back set to infinite, tried 1000 days for data series and everything I could think of. I've tried several Protected Override Void settings. The script compiles with no errors and only one warning because I made a parameter to change the Entries per direction in the settings rather then the code.

What line of code is causing the error? (If you are unsure add unique prints above each condition or action)

[Conceptzx]

I thought I added it, but it disappeared when I added the second clipping, I updated the previous post

Hello Conceptzx,

I see the error is an indexing error.

What is the line of code causing the error?

[Conceptzx]

How do I find the line causing the error? Everything looks good in Ninjascript Editor

Hello Conceptzx,

If you are unsure add unique prints above each condition or action.

Below is a link to a forum post on using prints to understand behavior.

https://ninjatrader.com/support/forum/forum/ninjatrader-7/strategy-development-aa/99209-date-conditions-not-working?p=791121#post791121

The last print to appear will be one line above the line with the error.

Does this make any sense? It fails when I enable.

Is there a print input that would give a full report of operations?

Are you calling AddDataSeries in your script?

[NinjaTrader_ChelseaB]

Hello Conceptzx,

Have you added unique prints above each condition and action?

Print("step 1");

if (Conditions)

Print("step 2");

etc?

Which of the prints was the last to appear?

[Conceptzx]

I do not have a data series defined because it was intended to be used on several instruments and time frames. I tried step 1, step 2... But I get the same output.

Hello Conceptzx,

Just to confirm, you are getting this output from the NinjaScript Output window?

None of the prints you have added at all are appearing?

Try printing from OnStateChange() above the State conditions (for all states).

Does this print appear?

[Conceptzx]

I tried on printing from onstatechange already as well. Yes that's why I get from the output window when I try to enable the strategy.

I'll probably just start from scratch again and add things one by one to see where it finally breaks.
