I do not fully understand the operation of orkdelta.github.io I can not sell my tokens.. sell orders are canceled by themselves. 0.01 ethereum deducted from my account. but sales did not materialize.. interesting..
There is such thing as order expiration time, in blocks. By default it is 10'000 blocks, that approximately a week. And if your order was not filled through that time, it will be cancelled automatically. You should manually out number of blocks for expiration, 100k or 1m for example. Then order shall have more time to be filled.
thanks for comment, It's not a week, I think it's a few days. I never liked this place. my orders are canceled. and my ethereums is disappearing.
