I would be a great feature to keep the loans.
the question is another, let me put some context on this
I mean for example you take a loan for 1 year at 150% APY and the rates goes down to 90% APY will you like to be forced to pay 150% for one year ?
Another feature that I'd love to see is the ability to close out a position when a total profit of x.xx or x% has been made.
So basically it would take both the P/L and Swap into account, and if together they were at the target value, then it would close out your position.
if you are long 100 BTC from 100 just put a sell order for 100btc at 120usd and the position get closed when the price gets to 120 the oposite works when you are short
