I ran an optimization on a strategy. I set PVs for a single symbol from an optimization results row. Those PVs appear correctly when I turn on the PV button. However, when the PV button is off, the default strategy param values, from the CreateParameter calls in my code, do not appear in the Strategy Parameter window.

Normally I can toggle between PVs and my code default values by toggling the PV button. Now, however, I cannot get my code default values to appear and be used.

The values in the Strategy Parameter window appear in the strategy XML file within the <ParameterValues> tag. I do not recall what these values are or where they came from. These values appear regardless of which symbol is selected.

I tried toggling Preferences > Advanced Options > Save the following items... > Parameter Slider Values, restarting WL, and clicking "Reset" in the Strategy Parameters window, all with no effect.

How do I get WL to go back to using the default parameter values in my code?

WL Pro 6.8.10 64 bit.

Thanks,
Ron

You must have saved them as default inadvertently. See this FAQ > Why am I unable to "Reset" and "Save parameters".
