Well the share is GUARANTEED TO MOVE STRAIGHT AFTER YOU SELL!!!...problem is you never know which direction.
If you want the profit take it, then wait and see what happens. If you sold to early (in this case I doubt it for the next few days maybe week) and the share runs up re-look at the reason you bought and why you sold. Then look at what the share is doing, what your time frame is for holding the share and decide if you want to buy in again? only you will get less share but the share price moves up you again profit.
Opposite is true, you sell and the share drops, WOW WHAT A GENIUS YOU ARE FOR SELLINH HIGH!!! Congratulations, and you can again re-look at the share to decide to buy at 282 again or what ever and wiat for it to rise again.
Onl you can decide how much profit to take and when.
A good punt: 306-282= 8% profit - not bad and you could do that 3 times in the next month (hypothetically) and get 24% profit rather than the 320-282 = 13% waiting for it to hit R320 and that could take 3 months..... on course it may not always go from 282 to 306 and back again but I am sure you see the sequence of profit...
