Tradingview strategy orders with a fixed tp and sl send to the exchange should get the possibility to choose for a SL % of full balance.
E.g. i open a position. My signal contains the TP and SL price. I want my trade to always lose the same % of full equity when i lose the trade. For every trade finandy needs to calculate the amount of contracts to be bought.
This way i always take same risk in % compared to my full balance.
