Can you adjust the margin trading "fix" for the infinite orders? Now I can only put buys for as much coins I have in my short, but I can't do a buy for 100 btc @ 50$ for example. Can only put enough buys to close my short, but not to open a long.
Thanks Indirectly,
You just answered my question,

Confirmed: You can close your "long" when selling BTCs in the "Margin Trade" tab.
I believe the position is still there, with "0", but with no loans and (hopefully) a profit left over.
Ente
Now, can a short be closed with a counter limited long buy position of equal amount btc ?
a buy limit order to close the short can be placed ahead of time allowing one to bracket the orders.
