If you ever find yourself trading on a leveraged trading site, especially Bitmex, it's extremely important you employ market stops and not limit stop losses. Prices can slip right past a limit stop and not execute, whereas the market stop will at least execute and you'll close somewhere near where the market stop is located. You don't get a rebate on Bitmex with a market order, but it's better than a stoploss not executing.

You should also always enter a trade with a stoploss. It's just as important as your exit and entry, and it's also important you use TA to determine where your SL is located so you don't get hit in a stop run.
