hi, wanting some advice from the experts. when both buying and/or selling, one can put in a "reserve price" so to speak. when selling, does this not limit or conversely disadvantage one, ie perhaps the ruling price would have made for a higher sale price. when buying, you put in what you want to pay, but what if the share price suddenly drops ? guess my question is, is it better to simply let the markets ruling price determine the buying / selling price or is it better to peg the value so to speak and hope the eagle lands. also, is it better to sell big parcels or smaller parcels of shares ? any pointers for some ins and outs ?
