So I had another Mercatox moment today. A few hours ago I placed a limit buy order of 25,000 DNotes for 620 Satoshi. At the time there was a standing sell order of 400 DNotes for 620 Satoshi. So as soon as I placed the order I immediately bought 400 DNotes and that eliminated all sell orders for 620. Not too long after that, A sell of 25,084.1 DNotes at 620 Satoshi executed. But not one bit of my standing limit order at that price was filled. It still sits on the order book at 24,600 DNotes for 620 Satoshi and it might never fill because the price has been going nowhere but up all day. Since placing that order triggered the standing sell order to fill, I would think that meant my order was first in line. But instead, some other order filled first, and mine still sits there waiting.

How is this explained by technical difficulties?

I see no other orders for 620 Satoshi and haven't for hours. As far as I know, my order is the only one, and if there were invisible orders, mine had to be first. And yet, it wasn't the first to fill when someone else sold more than the amount I'd ordered at that price.

I feel like I'm playing by a set of rules I do not understand. Is anyone else trading on Mercatox? Could you share some insight?
