if you are buying in the safe circle you are expecting a bounce atleast to the prior base and maybe even past it.. but yeah, I always take a gift (if a few minutes after my entry there is a quick bounce and Im in solid profit, I will take profit) Those quick bounces are gifts..
However I prefer it when after my first buy there is still more panic and I get to buy again, more, lower.. Because I like to have big positions when its possible.
