Coloring Bars if lower than SMA1 & Higher than SMA2

Hello everyone, 

I'm pretty new to C# programing, & i tried to recreate my TradingView indicator in cTrader.

What I want to achieve: If a candle opens below my fast SMA & close above or equal to fast SMA it get a distinc color.

When I try to solve it I got the folllowing error message:   Error CS0019: The following operator cannot be applied „double” and „cAlgo.API.IndicatorDataSeries” type operands: „>”.

Is there any solution for this? 

Thank you in advance,

Matt
