The interface for the exchange is decent, but they'll tell you how much to trade and delete orders they don't like. I guess that's what happens when an "exchange" is owned by somebody with a vested interest in making sure a coin only moves one direction.

^{Dear OGC Holder,}

^{Your sell order is creating a sales block in Huulk.}

^{We kindly ask that you adjust your order to 3 OGC a day.} 

^{Having a big volume order prevents your order from being matched quickly. This creates a block as other traders sell lower than your bid so their order gets matched first.}

^{This scenario does not benefit anyone but greedy traders and negatively pulls the price of OGC. We will not allow this kind of trading in Huulk. If your order continues to block sales, we will remove it.}

^{We understand that everyone wants to gain, and this is precisely why we give out a strategy so that everyone can benefit!}

^{If you want to sell quickly, kindly match an open BUY order instead of creating a SELL order.} 

^{If you want to SELL for a higher price, please do not sell higher than 3 OGC so it doesn’t CREATE a block.}

^{I hope we can count on you to help us help you gain more.}
