You guys need to understand how Cryptsy works. If someone buys @ 500, an order at 300 will not execute before the ones below that are sold.
so it reached 500 without going through my orders @ 230, 300, and 400?
The trade price never reached that 556, it was just a *single* buy order that someone (probably a bot or a manipulator) put in and it was filled with the lowest sell order. However that seller *did* get the 556 per Doge for that order, since Cryptsy always gives you the best (highest) price.
Since Cryptsy has a minimum sell amount of 100 Doge, it is very likely that this 556 price was for a minimum order of 100 Doge, so it is still only 0.000556 BTC (approx half dollar).
Or maybe someone made a bet "I can manipulate Doge price above 500, I bet for $20". And so he won $19.50
If you know how Cryptsy works, things become easier to understand when you see these peaks.
I am not too sure how there can be peaks in the dowward direction - apparently sometimes Cryptsy also executes orders that a for example selling at 100 and it shows, which is weird because there are always Buy orders for much higher.
this must be only on cryptsy then as ive never seen it on the FX markets......when i got home and saw that huge spike @ 556 i was jumping up and down only to find out my trades didnt go through ahahaha crushed me lol had a few mil on trades
