OH...just look at Level 2, if the current price on it is at 0.017, then you use 'sell limit'' and put the limit 0.017.
But if you just click sell and u sell..u are selling to the buyer at the price which the buyer wants, not your own price. easy as that...
some people look at the bid to set their selling price...that is bid whacking, it kills a running stock and scare people off. hope it helps
