I conducted a deep analysis of the fourth wave of Bitcoin's weekly chart using a three-dimensional integrated trading system that combines natural trading theory, on chain data, and volume price relationships. The final predicted rebound high point is in the range of 72800-73500. Capacity depletion, head, shoulder, top, and right shoulder are under construction. The following is a complete analysis of the three-dimensional integrated trading system: 1、 Fibonacci channel data extraction From the chart, I extracted the following key data: Starting point (0): 59828 US dollars (February 28th low) Endpoint (1): 71531 USD (Fibonacci 1.0 Extension) 1.618 expansion bit: $78763 Current price: 71535 US dollars (exactly around the 1.0 expansion bit) 2、 Analysis of Natural Transaction Theory (Direction of Judgment) Quantitative analysis: From the chart, it can be seen that the trading volume column in recent days has been significantly lower than the level during the rebound period in February and March. In natural trading theory, this is a signal that long positions can weaken in volume - long positions are still holding, but their momentum is not as strong as before. On April 8th, a "long upper shadow+small entity bearish candlestick" was closed, with the upper shadow length being 3.7 times that of the entity, indicating a relatively strong bearish signal. The bulls attempted to advance to 72858, but were hit back by the bears. The primary and secondary quantities can be determined as follows: The bullish main volume energy (M) during the rebound period from February to March has been exhausted. The current long position energy belongs to the "sub volume energy (H/L)" level, which is not enough to push the price beyond the 1.618 expansion level. Summary of Quantitative Energy Analysis On April 8th, a long upper shadow and a bearish candlestick were closed, with the upper shadow length being 3.7 times that of the entity, indicating a relatively strong bearish trend. The current multi head energy belongs to the secondary energy level, and the primary energy has been consumed.
