Hi drb2. Here is my thoughts on gaps.
I use the old adage, all gaps get filled. Sooner or later, sometimes months later, when you think, its long forgotten and “the price” will never go back there, wham, the gap gets filled.
When I look at a chart and see some old long forgotten gap, it gives me pause for thought. LOL, long enough to say to myself, this time the price will never go back there, buy buy, buy!
Breakout gaps, continuation gaps, exhaustion gaps, and gaps in general; nature abhors a vacuum.
Good luck!
