Back testing

[vit007]

Im testing my automated strategy and have this dilemma. I did run same strategy for the same time period on 2 ninja platforms , one has Rithmic connection another CQG and got totally different result. CQG shows good profit and Rithmic not so.
How its possible to have such a huge difference , its makes back testing totally worthless

Hello vit007,

Thanks for your post.

What version of NinjaTrader are you using? You can check under Help -> About (Example: 7.0.1000.X)

What interval is selected? (example: 150tick, 1min)

Do you receive an error on screen? Are there errors on the Log tab of the Control Center? If so, what do these errors report?

Do you see the same thing happen with the SampleMACrossover strategy?

Looks like I found the problem but Im not sure what its means ....error in the log .
Im running the same strategy on other NT7 with CQG tick data and have no problems but Rithmic gives me this message ...

Hello vit007,

Thanks for your reply.

This are script errors. Since this works on CQG however we will want to look into this further.
Is this a multi data series or multi time frame strategy?
Did you code this strategy?
Do the settings for your chart and strategy match when using CQG and Rithmic?
