MultiCharts: Trading Software for Automated Trading and Backtesting

I tried to conduct a walk forward test for a strategy.

however the attached error message occur during the test. I have already used tick tick to generate a daily chart for the test.

I set the OOS: 240 bars and IS: 960
my data is available from 1.1.2001 to 30.12.2013



what should I do to make it right?

Hello dingmanhoe123,

Does the error appear when you are using your code only or when using any of the prebuilt signals as well?
