Come across lots of fab gainers on these BB's nice one on BP guy first time into stocks made enough to pay deposit on house and fees etc from recent BP rise, no diversification all in on BP but paid off for him.
Depends on the platform you trade on ...etoro and plus 500 allow you to sell based on each trade you make and not average which i think is better but say a bank would average the price you have paid which i disagree with!
i lost alot on this when sank from 1300p because of my greed closed my hedge positions and it still dived lol Back in today with a play that i think will deliver 10/20% over the next few weeks
