Additionally, looks for exchanges that allow for cross margin as this will work the same sort of thing (but be careful with that).
That is true, cross margin will also work on which user will be able to transfer more collateral from their sport wallet to the their margin account. While if left in isolation margin, user will not be able to transfer collateral.
I also think if a trader has opened a position already and he chose isolation margin, he will not b able to convert to cross margin accept when he closese the trade to open new position using cross margin. I hope I am correct about this.
