Demetra Crocevia

Demetra Crocevia is a mean-reversion Expert Advisor for MetaTrader 5. It measures how far price stretches from a long Bollinger-style mid line and can open positions when stretch and slowdown conditions are met. On hedging accounts an optional grid can add levels. On netting accounts the EA limits itself to a single position and does not expand the grid.

How it works

- Builds a C-level distance unit from volatility around the mid line.

- Starts a series after confirmation that stretch and slowdown conditions are met.

- Optional grid adds up to a configurable maximum of real levels (hedging).

- Take-profit logic is mainly virtual (no hard SL/TP on the server by default).

- Safe Exit can arm on drawdown or age and close on pullback or recovery.

- Optional regime filter (pair volatility / trend; S&P symbol if available).

- Emergency Control (EC) can block new series or adds after a daily equity drop.

Symbols and timeframe

- Default watchlist includes major FX pairs (editable via InpSymbols). If listed symbols are unavailable, the EA falls back to the chart symbol.

- Default timeframe: M15 (InpTF).

- Designed primarily for hedging accounts. Netting is supported in reduced-safe mode.

Risk inputs (read carefully)

- InpAutoMM = 0 uses a fixed minimum-lot path (recommended for testing and Market checks).

- InpMaxLot hard-caps volume (default 0.10).

- InpMaxRealLevels, lot mode / InpLotsMartin, InpMinMarginLevel, InpMaxSpreadPts, Safe Exit and EC parameters control exposure.

- Grid and martingale-style sizing increase risk in strong trends. Use demo first. Past performance does not guarantee future results.

Demetra guard

- Trades only its own magic prefix (default 9130000). It does not manage other EA positions.

Requirements

- MetaTrader 5, hedging recommended for full grid.

- Enough history for the BB period (default 400 bars on the working timeframe).
