Layout order: Layout a high short on the daily chart if the Rebound does not break the 30 line or if it forms a long wick candle. The 5-day middle band should not break approximately 4170-4250 4310, betting on its second daily chart pullback.

Today's trading idea: 4-6 hours closing, place orders according to the Bollinger upper and lower bands (4007 3900 3880 3760), be patient for long wick candle trades (higher level requires patience).
Long position aggressive: If the previous low does not break 3900, look for 3880, 3870, 3850. As long as 3850 does not break, remain bullish. Stop loss 10 points down, bet on a 15 Rebound.
Long position 2: Buy at lower band 3760 on 4-6 hour chart with stop loss
Break below single: 3760 (bet it opens at the lower band in 4-6 hours)
Breakthrough levels: 3950 4006 4080
Pay attention to any point that breaks down or breaks through, as these are key points. Once a failure occurs, immediately reverse your position.

Short Position 1: Enter short at 3980 if the middle band of 30 line does not break. Must use stop-loss.

The short position two is the same as the breakout position 4006 4080

Set a stop loss for Ethereum at 10 points, Bitcoin at 350.
