There are several things to take into consideration when determining whether a trend is about to end or has ended: (assuming trend was an up trend)
1. Is price still above the supporting major trend line.
2. Price has stayed above previous major low (higher highs and higher lows).
3. Up waves are longer and stronger than the down waves.
