The 15-minute level of BTC has selected a downward trend from the high point of 83817. The last minor level movement has broken downwards through the last medium speed point, forming divergence point 1 for buying. Turning point: the first type of buying point appeared at 74508, after which a minor upward movement ended, and then the secondary level movement ended with the appearance of buying point 2. The current real market feedback is that the high order of 81300 has seen higher trade volumes with a hammer candle. Currently, the market is patiently waiting for a 15-minute level upward movement to approach this high point for shorting, specifically around 80500, with a stop loss of 800 points. Personal suggestion: investment must be cautious.
