'Gaps must be filled' isn't a 100% iron rule? The most common mistake in a bull market: seeing an upward gap and waiting for it to fill before jumping in. And the result? It only gets filled in the bear market, and by then, you've already missed the move. Gap filling is a false proposition. Let's look at the logic: there are four types of gaps—breakaway gaps, continuation gaps, common gaps, and exhaustion gaps. Common gaps do tend to fill quickly. But breakaway gaps and continuation gaps? In a strong trend, they might never fill. Why are gaps in a bull market hard to fill? - Market sentiment is high, and small pullbacks are immediately bought up - Fundamentals support the price, so it doesn't drop back - Profit-takers are reluctant to sell, so there's not enough selling pressure The gaps in Bitcoin's recent rally are a perfect example. The fundamentals have undergone a fundamental shift. Waiting for it to fill? You might have to wait until the next bear market. 'Gaps must be filled' never specifies a timeline. If it fills three years later, five years later, technically it's still considered 'filled.' But what about your cost of capital? The right mindset: in a bull market, gaps are support levels, not bottom-fishing levels. Filling the gap is an opportunity, but don't treat it as a certainty. Have you ever missed a move because you were waiting for a gap to fill?
