Also, can someone help me with the Stop-limit on poloniex?
For example if I buy ETC at 4170 and it rises, and then it fluctuates alot and I still wanna be in but if it goes to 4200 I want to sell. How should I set it up? If that's even possible?
The stop is the trigger - when you hit this price, it will trigger the sale or buy order. The limit is the same as the price in a buy or sell order.
So if you do a stop-limit sell with a stop at 4200, with a limit at 4100, when the price hits 4200 it will trigger a sell with a price of 4100 or higher.
