Characteristics of a Strong Upward Trend:

1. Moving averages are in a bullish arrangement, and most K-lines are moving above the moving averages, with more bullish bars than bearish bars.

2. The overlap of the real parts of consecutive K-lines is low, indicating that the price continues to rise, even if slowly.

3. The upper and lower shadows of K-lines are relatively short.

4. After a breakout, the pullback's lowest price is higher than the breakout's resistance price line. After a significant breakout of the resistance level, there is a high-level consolidation, and the price movement during consolidation is relatively narrow.

5. The price has never fallen below the small time frame moving averages.
