It did happen intraday but I also think that it's a rare occasion when you can ignore that price point on the chart.
What happened was that the buy side order book was quite sparse (as is often the case on stocks like XEL which are still largely MM books) and the MMs were all positioned at pretty much the same buy side price. Market sell orders took their entire positions and left the buy side completely empty while they re-figured their positions. An unfortunate seller got their order filled at 35.84p at that time (negotiated trade probably). I don't think it was an AT trade, probably an O trade but it was certainly outside the normal trading range.
Anyway, I'm thinking that if I ignore it (and the bullish divs at the subsequent low of 64.75p suggest that that was the genuine low to me), and do a projection of the move up from 64.75 to 139.4 and back to 83 we get a interesting target at precisely the 20p high. This would also formed nested cup and handles if the shorter term targets of 139 and 150 are met from the 83>110>94.5p move are met.
There are some nice convergences of targets possible here.
