im having the same issue with yobit, i ordered 729.895 Ecash @ .80 and at $1.20 went to sell and realized they only completed 177 and the rest is in some sort of reserve.
are you familiar with this? if i cancell order will i get the price i cancelled at or did i get shafted?
it was in reserved order and i was unaware so im screwed out of alot of money only got paid for 177 instead of the 729.895 so they got me on that one. ill always cancell my order right away and rebuy next time this happens.
Poloniex had probably a DDos attack at this time. Your issue is resulted by another problem. Mostly orders are not fullfilled completely, when the trading volumen is too low at the given price. It also happens for example on poloniex and cryptopia. This issue can only be solved, when you cancel the order and wait for a good price to buy again and reach the trading minimum to sell it completely. I have a few of these residual amounts.
