Ok, I sold for 700.433$ and now I wanted to buy 2% cheaper so I made:
My order last sell price - goes less than 2% spend my all USD - at market ask price

But didn't worked when the price reached 686.42$. The offer did not jump from Rules to Your open orders.

Anyway, the idea is to find a way to sell higher then I bought and next step to buy cheaper then I sold. The point of reference should be Last sell price, last buy price, not the trigger moment and balance.

Automaticly so I can forget to follow things.
