Reaffirming the methodology:

Use 4-hour K-lines to determine trend. Confirm that stock prices are moving along an upward channel and holding above the 20-period moving average, directly filtering out all weak stocks in a downtrend.

Then overlay three indicators triggering signals simultaneously: MACD just turning red above the zero axis confirms bullish momentum; WR Williams %R breaks through the 80 line from the oversold zone above 90 to catch pullback lows; MTM crosses above the moving average to form a golden cross, verifying upward momentum. Only enter when all three conditions are met, and take timely profits or stop losses upon a breakdown.
