When trying to buy a really small amount of BTC, it gives the error message "1: Amount too low". I suspect the '1:' is some sort of error code? Perhaps it's more useful to mention the minimal amount in the error message.

EDIT: Found a more serious one now.

I set a buy order at a ridiculously large amount of a million BTC for market price, at 1:250 leverage. I had $14k in my balance. Then something weird happened: the order got executed for 250.82679898 BTC (worth exactly $25k), but my balance remained untouched. Then the order was canceled automatically (and it is now listed as 'canceled' in my 'Closed orders' list) because the 'Margin allowance exceeded'. Not everything was unchanged, though: my fee-progress-bar jumped straight through four levels, to the point where it's now nearly at 0.36%. Being able to use this in a controlled fashion would make it a very viable attack to get into cheaper fee regions Tongue

I have thus been unable to reproduce it, but I'll keep trying. Perhaps you can see more info on the back end. It's trade order OYHWZH-PXEQY-PWFHKU.

Yeah, it would be good to actually tell you what that too low threshold is. For BTC/USD it's an amount that would be worth less than $0.01 USD.

It looks like what happened with your 1:250 leverage order is that you hit the $25k per user cap on margin. So, the remainder of your order got canceled after you ran out of margin and it filled $25k worth, which you should now have an open position for. My guess is your fees were already < 0.4% when you made the order. The margin cap per user isn't displayed anywhere so you couldn't have known and that's something we need to fix. Thanks for the report!

Bug signing up. I accidentally entered my password as the user name, now it will not let me enter that password. even after I changed the user name.

I'm not sure I understand you. We don't allow you to change usernames, and we don't allow you to have your username as part of your password. Can you clarify?

Are Ripple meant to be something that we can trade? Also, I notice that unlike gox you can only put in as many orders as you actually have funds, is this intended behavior? On Gox if it eats through all your bitcoin or dollars it cancels any remaining trades.

Yes, you should be able to trade XRP but the market is probably pretty shallow or nonexistent so you may want to check the order book.

Yes, setting a limit order will reserve that currency so you'll be unable to set up orders for more than you have. You can, however, use the stop orders and conditional close to somewhat bypass those restrictions.
