saintbirdThe logic of the placement part is not well understood, why the value is Math.min ((CoverAmount, pos[0].Amount), instead of pos[0].Amount?
youtiaoThe damage is too great.
Quantification of district classesIf everyone is mining, I'm afraid this strategy will fail very quickly. If the market goes to extremes, it's easy to go bust, and then the fmex that is booming doesn't lose enough capital.
mingren1992FMEX's interface is accessed via HTTPQUERY? Just switched from BITMEX, does FMEX support Exchange.IO haha?
FlyingIf you have a lot of money, you can easily make a loss on the basis of the price of the stock, can you change it to the next level of the stock at the same price?
FlyingCan you add a maximum leverage set? Tests are continuous and easy to crack. When this limit is reached, you are reminded not to place orders.

The grassThe code is for reference and needs to be optimized.
