The price you place at your first sell order remains the same. No need to change anything after you have placed a sell order.
If you want to change the selling price all you have to do is cancel your previous order and place the new price ;).
I suck at trading so I can't give you many advice bro.
:) I think you're doing pretty good overall.
Ok, cool, now i know how to "change" the price.
Thanks!
