lol... it dropped below 1p yesterday for no real reason and back up to last weeks close today now. 1.5P placing and warrants in play here - low mcap low shares = big moves on small trades.
GL.
It's not obvious. Your pf value goes up by however many shares you had but 1p for each share. So if you had 1000 shares your pf value goes up by a quid. Lol
