Here's a detailed description of a Breakout & Retest Supply and Demand strategy-based Expert Advisor (EA):

Strategy Overview
The EA will implement a Breakout & Retest strategy based on Supply and Demand zones. It will identify potential supply and demand areas, wait for a breakout, and then retest the zone before entering a trade.

    - Swing highs and lows
    - Consolidation areas
    - Imbalance zones
2. *Breakout Detection*: The EA will monitor price action and detect breakouts above or below the identified supply and demand zones.
3. *Retest Confirmation*: After a breakout, the EA will wait for a retest of the broken zone to confirm the trade.
4. *Trade Entry*: The EA will enter a long or short position based on the direction of the breakout and retest.
5. *Risk Management*: The EA will implement risk management techniques, such as:
    - Stop-loss placement
    - Take-profit targets
    - Position sizing
