Yes I have done that on stocks and now on Options I have only two stock left I have 100 shrs of TWTR out of 1,000shrs I got them a few days after the IPO for around 33.00 , sold half at 71.00 then 200shrs at 68.00 and 100.00 65.00 and the last at 55.00 I will hold the last 100.00 just for giggles or something? the other is HEMP I bought a long time ago for pennies( something like 40K shrs, I wasn't watching ( I almost forgot it LOL)and missed the run up to over .30 a few weeks ago.
Now I'm only playing with Options to give me something to do. I feel I'm lind of a Dumb ass at it LOL but with a few rules I make some $ but leave more on the table them I make LOL I'm trying but it's all too fast for an old dog Flip
