MU order book buy depth 42.69, sell side left with only 24.54; a 1.7x order gap on the board. The chips underneath were already scooped up by big orders. On the 4H and daily charts, the direction is fully biased to the long side—this sell-off is just a pullback to wash around the short moving average, not a trend reversal. Buy at 850, targets 888/920, stop-loss 812. If it breaks the 24-hour low of 845.72, don’t be stubborn.
