Three dimensional integrated trading system | BTC market analysis (3/3): structural form and core judgment Narrow range oscillation pattern, 80.6K is the short-term defense line, 77K is the extreme bottom, and above 85K is the resistance level. The cost of new giant whales, medium-sized giant whales, and Fib 1.272 quadruple resonance are all around 77K. After falling below 80.6K, the space below is limited. At present, excluding black swan events and major bearish factors, below 77K is a golden pit. Xiaolong's core judgment: Geopolitical risks are still heating up, with the US and Israel rumored to hit Iran again after the midterm elections. The November 3 midterm elections and the December 29 Fed rate hike are variables hanging over Bitcoin. So, before all these variables have landed, the volatile market of Bitcoin will continue and there will be no one-sided trend market. Short term trading opportunities, long positions at 80K-81K, take profits near 85K, and short positions at light positions. Do not hold heavy positions in contracts, buy heavily due to a sharp drop in spot prices, and do not fill positions temporarily.
