Yes.
All trades within the ISA wrapper are allowed and 'contained', not counting as additions.
I you take cash out you cannot replace it within the same year.
You could, for example, put in 20K, and double it or trebale it with a single share rise, sell it off, invest the cash in something else and reap 7% on those stocks for the rest of the year. No problem, all tax free!
Then put another 20K in the following tax year.
