At market close NXTD was showing hints of spiking. So I bought it into the market close. This is the biggest position I have had before. I don't know why it took me this long to work out, but my position size had been so small that it was really doing me no good in terms of profit. So this 750 share was a way to make something back in one trade. But I cannot escape the fact that this was a revenge trade - just being honest.
