April 20 Market Analysis:

BTC：
Today, watch the previous low at 73660. As long as this level is not broken, the daily level remains bullish. For the smaller timeframe rebound, watch the white line at 75200. If it cannot break above this level, it will still come down. Only when price holds steady above 75200 will this pullback be considered over.
Resistance 76350-78000-79300
If today price breaks below 73660 and tomorrow morning the daily candle cannot close back above it, then the daily level will start correcting.

ETH：
Today, watch the 2315 level. Only when price holds steady above this level will this pullback be considered over.
Resistance 2365-2416-2463
If today the 4-hour level cannot move above 2315, it means the smaller timeframe lacks momentum. The 4-hour level will continue to trend lower in a correction.
