Walk-forward parameters auto-set to default values

[haakonflaar]

See the image below. Even though I define a walk-foward optimization range, for all optimization periods all optimization parameters are set to its default value instead of testing the min;max;increment. How do I fix that?

Hello haakonflaar,

Do you see this also happen if you set a min/max using the SampleMACrossOver and its slow and fast inputs?

Hello NinjaTrader_Jesse,

The bug happens when I create a default template that sets the walk-forward parameters. When I activate the template, the values are correctly set in the strategy analyzer UI, however, it's optimized solely using default parameter values. If I delete the template, and manually add the optimization ranges everything works as expected. So it does work with the sample strategy.

Using a template worked perfectly fine up until recently and I've made no changes or updates to NinjaTrader. I've tested on multiple computers and I get the same bug. Any idea on how to fix it?

Hello haakonflaar,

To confirm do you see that with the sample or only your custom strategy? If you see that with the sample I can collect the steps to test and report that if it is a problem.

NinjaTrader_Jesse Turns out error was because the type of the walk-forward parameters were set wrongly (int were set as double) in the template I used.
