How long takes buying or selling because i wait 10minutes and still nothing. I wrote price corectly
Erm, i can't understand your question. Please, provide more information about your case. I think (w/o info, just based on your newb status on account) that case may solved by explaining this:
On exchange, you buy or sell to someone. And if you trying to sell, for example, 100 pot for 100 LTC - you can place a bid (SELL button), but it's really little chance that someone will buy it.
Update: yes, i see on your account buying bid for 0.009 LTC per UTC, and it's not even the highest bid.
