MAM Black

Overview

MAM Black is a profit-only grid system engineered for the S&P 500 / US500 family of symbols.
It builds a one-sided grid in the direction of the EMA slope, controls distance with ATR, and exits only on profit using equity-based targets and trailing. When risk conditions deteriorate, it automatically freezes, pauses, or light-hedges to protect the account.

The logic is transparent and broker-compliant: no martingale multipliers, no scalper tricks, no DLLs.

Key Features

• Trend-aligned grid – entries allowed only when price and EMA slope agree.

• ATR-adaptive step – grid distance = max(GridStepPoints, ATR*multiplier) .

• Profit-only basket close – closes a basket only above a configurable profit ( TP_GridEquity ) or equity-trail thresholds.

• Equity-based trailing & skim – locks gains with TrailingEquityPct , LocalDrawdownClosePct , and optional partial “skim”.

• Freeze / Pause states – auto-freeze on equity drop or long basket age; auto-pause on daily drawdown cap.

• Trading session filter – trades only within user hours; after hours it seeks a small profit and stands down.

• Anti-spike guard – ATR-range blocker + time cooldown to avoid volatile bars.

• Optional auto-hedge – reduces net exposure when margin level or equity drop conditions are met.

• Whitelist for symbols – runs on a curated list (US500/SP500 variants); a minimal validation fallback exists for Market checks.

• Position handling – robust ticket-based management (no PositionSelectByIndex ).

Recommended Use

• Instrument: S&P 500 / US500 symbols supported by your broker (e.g., SP500m, US500, US500.cash, SPX500, US500m, SP500 ).

• Timeframe: M5 internal signals; attach on any chart.

• Account type: MT5 account offering US500/Index CFDs.

• Default profile: Start with the provided defaults; adjust InitialLots , TP_GridEquity , and MaxPositions to match balance and broker limits.

How It Manages Risk

• Daily risk cap: SL_Total_Pct pauses new entries for the rest of the day.

• Equity-trail: When equity pulls back from a local max by TrailingEquityPct or LocalDrawdownClosePct , the EA attempts a profit-only exit or skims the basket.

• Freeze logic: FreezeDropPct and FreezeAfterHours stop layering until conditions improve.

• Switch control: EMA-based trend trigger flips the side without closing in loss.

• Session discipline: outside TradeStartHour…TradeEndHour , the EA will only try to flatten in profit.
