I've been trading on forkdelta for some specific tokens and there's a lot of problems with order book bid price is higher than ask price when trying to sell on a bid price it says order has been filled, if order is filled why it's still in the order book and also the lower price orders filled rather than high price orders and order book not updated for hours even if trading pair is too active, i can't examine the real buy sell prices at forkdelta is there any solution for that or it'll goes like this.
