How can I reset the selwins variables?

Hi,

I need to reset the selwins variables in a trigger, for example s_1_selwins_30. I have tried to make it with "reset channel's total won", "reset total profit/loss" and "clear w/l/z history" actions in a trigger, but nothing of these works, I cannot reset to 0 the selwins variables.

How can I do it?

It will reset when you start the channel.
It can't be reset mid run.

I can't really see why you would want to reset it.

It's not calculated value, you can't reset it.
If you need custom calculation you have to create a user variable and count/reset wins with triggers.
