The sell orders on Etherdelta are hijacked by someone trying to hold the price down while they acquire as much PPT as possible. Its a crafty plan. They have filled the sell order book with orders at the same price and forced all higher priced orders to be canceled.
How do we beat this and give PPT a chance to find its equilibrium price?
I'm not sure about that exchange's working system. Normally it has to match buy and sell orders but sometimes you can sell higher than buy order or lower than sell order. I don't quite get it. I still hold my coins and I see somebody (or a bot?) put a lot of same orders in 0.01234 and 0.0198. For that reason I can't see other orders in orderbook but when I look at Depth chart it's clear that buy orders will eat this sells in a short time.
