Title: Problem with buying BitBTC
Post by: vegolino on October 09, 2014, 12:38:38 pm

I have just bought some BitBTC by clicking on the first row of Sell BitBTC Orders. Amount in BTSX was - 20,001.99993 BTSX. Order was executed and I received 1.57062294 BTC or equivalent 19,999.99999 BTSX. In Open Orders there was still order for difference 20,001.99993 - 19,999.99999 = 1.99994 BTSX . I don't know why is this the case, but I canceled it and had to pay 0.5 BTSX for cancellation fee.
I would like you to know that I am not complaining about 0.5 BTSX cancelation fee as it is not much, but I think that it should not happen as I clicked on Sell BitBTC Orders and was ready to buy full amount that somebody was selling. This is not about me, but about our future users.
Aloha to all  :)

Github issue open on that one .. its because prices are floats whereas btsx larimers are integer .. its a cs issue

Two factors.

When clicking an order it adds some overlap in the price. 

Rounding errors are a fact of life.
