Tradingview Binance Mark Price

OK, it took me lengthy enough (three months) to know that in Tradingview the worth is final and I ought to commerce by Mark.

My problem is the way to position and calculate positions, as the worth is totally different between those

For some purpose, once I put the place device in the Binance Tradingview chart, it doesn't give me a quantity to trade and I have to calculate the position measurement alone, which could be very error susceptible...

How should I'm going with it? When buying and selling using Tradingview to research, however I really need to use the Binance net app for entry?

Thanks all ????
