@Kunleesp This is correct.Breakaway or runaway gaps need not be filled. I posted identically on this subject today for another gold stock which gapped up hugely yesterday, making a big gain (but not this big). The stock has pulled back but not (yet) filled the gap, and I hope it won't. I'm hoping it's a runway gap Post 17605327 (and not an exhaustion gap)
This is a good reference:
"There is an old saying that the market abhors a vacuum and all gaps will be filled. While this may have some merit for common and exhaustion gaps, holding positions waiting for breakout or runaway gaps to be filled can be devastating to your portfolio. Likewise, waiting to get on-board a trend by waiting for prices to fill a gap can cause you to miss the big move. Gaps are a significant technical development in price action and chart analysis, and should not be ignored. Japanese candlestick analysis is filled with patterns that rely on gaps to fulfill their objectives."
