Hi,
Please explain how work this rules/code structure:

BuyAtMarket
some code
MC1
some conditions
MC2
some conditions
MC3
some conditions
SellAtMarket

Are these multicondition groups work independently, or they nested, like MC2 to MC1.?
I need they all MC's filter data like "and".
Problem is if i remove MC1 from the script, # number of trades increased many times for MC2-MC3 groups. Same thing about MC3, MC1-MC2 sharply increased # of trades.
But WLP help is: "A Multi-condition group having no conditions is ignored".
Thank you.

They are nested. The MCs are ANDed by default unless you put an OR on top of a MC group.

If you remove a MC group, no wonder that the number of trades builds up: the resulting conditions act as a less restrictive filter. But since it's not clear what you're removing, the MC tag or conditions themselves, please don't hesitate to illustrate with a screenshot.

A MC group w/o conditions is just an empty label. If you're removing the label itself from e.g. MC1, that's no longer a MC group - these conditions become part of "some code" (with regard to your structure above).

Doe's this mean MC2 is one of conditions of MC1 (nested) or conditions of MC1 AND next conditions of MC2.

Thanks.

If in accordance to help one MC ignored it should not be difference in # of trades if I remove this MC from the script, but it does.

How are your strategy's Rules set up exactly? You could attach a screenshot (PNG, under 3 MB) to illustrate.
