Migrate MAEA Expert Advisor from MetaTrader 4 to MetaTrader 5 platform with significant strategy simplification and architectural improvements. Key changes: - Platform: MQL4 → MQL5 - Indicators: Reduced from 5 lines (3 EMAs + 2 borders) to 2 EMAs with zone fill - Strategy: Removed pullback signals and dynamic lot sizing - Lot sizing: Changed from dynamic (0.01/0.02) to fixed 0.01 lot - Stop loss: Changed from Border Lines to opposite EMA (Buy: EMA Low, Sell: EMA High) - Signal logic: Added opposite signal close for reversal protection - New filter: Added minimum zone width filter (100 points) - Documentation: Updated implementation plans and project summary - New files: Added AGENTS.md, MAEA_Indicator.mq5, and opencode.jsonc BREAKING CHANGE: Complete rewrite from MQL4 to MQL5 with simplified strategy. Previous MAEA.mq4 and README.md deleted. New implementation requires MetaTrader 5.
