I would agree with your comments and increased volume of late, backs up your wind in the sails analogy. I think the price might come off a little more before it bursts upward again, but all just guesswork of course.
It has liked the support of the 50dayema before, but i feel that is too much of a drop, without the RSI falling below the uptrend and 50 level, so the sp might just drop to the 12.5p level intraday and use previous price support at 13.25p to base itself before another rise. Extending a line from the previous peaks to establish another high could give a price in the region of 21p, but i would expect the sp to overshoot the target intraday.
