I don't know the reason for gaps being filled, maybe someone can explain that. What I do know, is I watch them get filled in every market I trade in from crypto, to FX, to now stocks. That being said, currently, ONTX is at .51 and two gaps were filled by today's spill. And, one was ALMOST filled on the run up. But, there are 3 below us still at .32, .20, and .17. Above us is is .76, 1.40, 5.40, 11.50 and probably more higher. But I wanted to show here on the 4hr log chart the gaps and their fills. Those in green have been filled and those in pink have not. They don't always fill in order, other wise all the ones above would've been filled already, but they usually get filled. One crazy example is BTC1!, the Bitcoin futures chart had a gap at 13.8k from jan 2018 on the 4hr chart, it fell till 3k then in June of 2018 came all the way back up and filled that gap then pulled back. So, for the long term holders, this is great news. Might even put in some buys at .17. Of course nothing is a guarantee, but just food for thought.
Good fortune yall
