OT
as morgen says above (and well worth a read)......excel files can be found on the net (or other forums) that can help with determining (calculating) buy quantities (position sizes) based upon how much capital risk you can survive (both loss sell points and profit sell points for the same trade for a pre-determined risk level).

morgen is talking charts to get ideas for initial numbers (buy and sell trade values to place with broker) but then, if the stock keeps going up, changing from a pre-determined profit $ number to use a conditional sell order with the broker (trailing stop) to let the profits run.......

Good luck. (wrote this cos sometimes when the same info is written differently then there is a hope of putting it all together to work out what the blazes is being said - if it did not make sense the first time)
