Its a case of the price rising too quickly in a sideways/pessimistic market, especially with a few gaps as well.
Once it was obvious that resistance in the 90s wasn't going to break, buyers cooled off and retreated in the queue, allowing a cascade of small sells to push the price down. Then you get a mix of profit taking, stops getting hit, and finally outright panic as clueless latecomers who bought in the 90s dump at a loss in the 70s.
It'll keep dropping until either the big buyers decide to put a stop to it, or until the selling dries up. Guessing where & when that'll be is difficult - buyers could take over again within the next half hour, or they might let it fall all week.
