回撤再入场引擎

This is a long-only, counter-trend strategy that aims to buy dips in a medium-term downtrend. The entry logic is based on a confluence of four filters:

1. **Trend Filter:** The price must be trading below the 60-period Simple Moving Average (SMA).
2. **Oversold Condition:** The WaveTrend Oscillator must first dip below -60 and then recover above -55.
3. **Momentum Confirmation:** The MACD must show sustained bullish momentum for at least 2 bars.
4. **Re-entry Filter:** A new trade is only allowed if the price is at least a certain percentage lower than the last trade's exit price.

The exit is based on a fixed Take Profit target. This version does not include a stop-loss.
