No worries. I have very low time preference.

Sorry about that, we'll be pushing a major update tomorrow night. All these nagging issues have been fixed in that update.

I'll try again, but I was trying to sell small quantities of shares.

Yes, I noticed same as well, something is messed up with sell, please try with lower shares 100-200 for now.

We found the root cause, but it will be few days to get it working perfectly. We were using limit sell order flow (meaning you set a sale price, which is pre-set as of now), however, our orderbook still needs more work. 

Temporarily, we'll be switching to spot sell order  (meaning you will sell at what the current/market price is on the server). If someone sold/bought before that very second, just before you, you may get a slightly different sale price. With this no more nagging "Failed Order" to cancel.

Once we fix our orderbook, then we'll re-enable limit buy/sell where you can actually set a future buy/sell price.
