Ordinarily you would start with a deposit of USD, use that and some more borrowed dollars to buy BTC, then when you close the trade you sell all the BTC back into USD, repay the borrowed amount, then keep the remaining USD as profit.

If you 'claim' instead of 'close' you would only sell as much BTC as you need to, to cover the borrowed USD, and then keep the remaining BTC as profit.


If you set a Trailing Stop Buy with a distance of $10, the trigger price will start at $10 above the current price and follow the market when it moves down (so that you'll buy at a lower price), but stay stationary when the price moves up, so that if it ever goes $10 higher than the prior low-point then the Stop will trigger and buy coins, to either open a Long or close a Short.

If you set a Trailing Stop Sell with a distance of $10, the trigger price will start at $10 below the current price and follow the market when it moves up (so that you'll sell at a higher price), but stay stationary when the price moves down, so that if it ever goes $10 lower than the previous high-point then the Stop will trigger and sell coins, to either open a Short or close a Long.
