This pattern is identified when the price action of a security meets the following characteristics:
1. The price falls to a trough and then rises;
2. The price falls below the former trough and then rises again;
3. Finally, the price falls again but not as far as the second trough.
Once the final trough is made, the price heads upward, toward the resistance found near the top of the previous troughs.
