I just had some orders that got partially filled. How long does it take to get the escrow balance back after cancel?
It has been a lot of blocks since it was canceled successfully.
If you look at one of Counterparty blockchain explorers (eg. http://blockscan.com/order?f=0), you should see the expiration time (how many blockchain blocks are left).
Maybe (someone should verify) it’s not possible to cancel partially filled orders…
That would be a bug. If you could duplicate on testnet, I’ll submit a bug report for you.
