TradingView indicator based on another one

Hello, i need someone who can write an indicator for TradingView. In my opinion it shouldn't be anything complicated but i'm not a programmer. So we have indicator Multi Z Score [DW] and i need indicator that will draw X on a candle when:

Candle is Green there is a dot on Multi Z Score over 2

Candle is red there is a dot on Multi Z Score under -2

I draw it on na pics.
