BitMex trading interface

BitMex has actually one of the best trading design that I've ever saw.
This orange line on the top is my limit sell order. I can amend it while I'm watching the chart, without fees!

Green line with number 2 in the box is my current position.

Orange line below is my stop order in case the price goes down it will execute automatically and I won't use all the money in my order. I also can amend it just by moving it up or down with my mouse.
