With the arrival of 4 o'clock in the morning, the US stock market ended a week of operation. The quarterly Quadruple Witches still ended the six consecutive working days of the S&P 500's upward trend. After the bondage, the prices of #BTC and #ETH showed a significant increase (Figure 1). Also as of 4 a.m., the price of BTC futures on CME reached $26,445, and the price of ETH rose to $1,723.

Especially keep in mind the price of BTC on CME, because no matter what the reason for the price increase, and no matter how the price of BTC changes over the weekend, if there is a gap between the price of BTC and the price of $26,445 when CME opens at 6 o'clock on Monday morning , then a gap will be formed, and the more obvious the price difference is, the bigger the gap will be.
For example, when the price of BTC rose to 27,000 US dollars when the market opened on Monday, there was a downward gap between 27,000 US dollars and 26,445 US dollars (below 27,000 US dollars), and if the price of BTC was only 26,000 US dollars when the market opened on Monday, then There is an upside gap between $26,000 and $26,445 (above $26,000).
So no matter whether the gap is upward or downward, as long as the gap is within a week, there is a certain chance to fill it up, which is also called filling the gap. It is said that when there is a price difference between Monday's opening price and Friday's closing price, there is a chance to touch Friday's closing price again in the same week, and it is not ruled out that it is a pin. As long as the prices basically coincide, the gap is filled.
But in AlexZ's point of view, as long as there is a gap, there is an opportunity to fill it, regardless of how long you wait, and use this as a support for judging the price trend. According to this point of view, I re-drawn the CME (Figure 2) and marked several long-term gaps, among which the pink is the gap that has been filled, and it can be found that the long-term gap is indeed irregular, while the blue is the gap that has not yet been filled. As for the gap, you can see that there are two more gaps, namely the gap from $34,500 to $35,300 above, and the two gaps from $20,300 to $21,300.
If we look at the long-term gap that must be filled, the gap of 34,500 US dollars was created on May 9, 2022, and it has been more than one year now. The longest gap in the last three years is one and a half years. If this assumption is true, there may be an opportunity to fill this gap at the top this year. Similarly, the gap of $20,300 was created on March 13, 2023, and it does not rule out that this gap will be filled at the bottom during this cycle. .
Of course, although the probability of making up the gap is very high from a historical point of view, there is no specific law and inevitability. If it is not made up within a week, then the timing will be very random and cannot As an inevitable point of view, it can only assist everyone in judging the price trend.
