IS Purple EA — GBPUSD & XAUUSD Scalper with 1.52% Backtest Drawdown

IS Purple EA is a MetaTrader 4 scalper trading GBPUSD and XAUUSD on the 1-minute timeframe, entering short-duration positions using pip-step logic with trailing exit control.

A 5-year backtest on $100 starting capital shows 742,198% total gain at 1.55% peak drawdown; a separate XAUUSD backtest on $10,000 capital records 85.42% win rate with a 6.16 profit factor over a two-month period.

Key Benefits

• ✅ Drawdown Control: Backtest peak drawdown held at 1.52–1.55% across 5+ years — achieved by targeting only brief, high-probability micro-moves, which limits exposure per session but restricts position hold time to 1–2 minutes maximum.
• ✅ Dual-Instrument Scope: Runs independently on GBPUSD and XAUUSD — two instruments with structurally different volatility profiles — reducing single-pair dependency, though both require tight spreads to preserve the small pip targets per trade.

  Compare EA strategies

• ✅ Pip-Step Grid Logic: PipStep of 26 controls re-entry spacing, capping basket accumulation under normal conditions — but consecutive loss runs of up to 26 trades are documented in backtest, meaning sustained directional moves against open positions create concentrated exposure.
• ✅ Configurable Risk Mode: Supports both auto-lot (risk % of balance) and manual fixed lot — auto-lot scales position size with account growth, which amplifies compounding but also amplifies drawdown dollar-value as the account grows.

IS Purple EA Performance

All performance data below comes from backtests run on MT4 — no live verified account is available for this EA.

The primary 5-year backtest (Jan 2018 – Mar 2023, Every Tick model, $100 starting capital) shows 742,198% total gain at 1.55% peak drawdown and a 15.04% average monthly return. A second run on the same dataset with $1,000 starting capital reports an equivalent gain curve ending at $1,760,980 at 1.52% peak drawdown.

A separate XAUUSD backtest (Jan–Feb 2024, M1, $10,000 capital, Control Points model) records 1,262 trades, 85.42% win rate, 6.16 profit factor, and 41.30% maximal drawdown — with 26 consecutive losing trades documented in a single streak.

Performance Snapshot

The XAUUSD backtest used the Control Points model — a crude approximation that MetaTrader itself flags as unreliable. The 41.30% maximal drawdown and the 26-trade consecutive losing streak are the figures that matter for capital planning: a $10,000 account saw over $8,700 in peak relative drawdown in that two-month window.

This is a structural risk, not a configurable one. The pip-step grid re-enters at fixed intervals regardless of trend strength — meaning a sustained directional move on XAUUSD will stack open positions until price reverses. StopLossPercent at 10% (input settings) provides a hard floor, but at 18+ lot sizes scaled through compounding, the dollar exposure at that floor is substantial.

Reducing the Risk input or capping lot size manually limits compounding speed but directly caps the exposure at the floor — this is the only documented mitigation. Post-mitigation return figures are not available from the test data; 90-day demo testing is required to classify the tradeoff at your specific capital level before going live.

These figures come from backtests only — the primary test uses Every Tick modeling over five years, but no live account data exists to confirm how spread, slippage, or broker execution affect these results in practice.

How IS Purple EA Works

Mechanism: IS Purple EA targets short-term price inefficiencies on GBPUSD and XAUUSD at the 1-minute timeframe, entering positions when intrabar conditions align and closing within 1–2 minutes at small pip targets. The strategy is designed for liquid sessions where bid-ask spread is minimal — the 2–10 pip take profit window leaves no room for wide spreads without turning winning trades into losses.

Signal Trigger: Entry conditions are not publicly documented in available materials. The EA operates within a defined time window (TimeStart: 2, TimeEnd: 23 server hours) with a re-entry spacing of 26 pips (PipStep) controlling grid placement.

Position Close: Trades close at TakeProfit (10 pips in the input settings) or via a trailing stop mechanism (Trail: 20). The EA manages baskets — multiple open positions on the same instrument — and closes the basket collectively when conditions are met.

Exposure Limits: StopLossPercent is set at 10% of account equity, acting as a hard circuit breaker. Risk input (0.01) scales position size relative to balance. Manual lot mode (UseManualLot: false by default) is available to override auto-scaling entirely.

✅ Optimal conditions: Liquid European and US sessions with GBPUSD and XAUUSD spreads below 1.5 pips; ranging or mildly trending markets where price oscillates within a session rather than trending strongly in one direction.

⚠️ Avoid when: Strong sustained trends on either instrument — particularly XAUUSD during macro risk events (FOMC, NFP, CPI) where price moves 10–30+ pips in a single direction without retracement, triggering grid accumulation without a corrective close.

Recommended Settings

Who Should Use IS Purple EA

• ✅ Running MT4 on a VPS with uninterrupted 24/5 connectivity — trades close within 2 minutes, and any connection drop during an open basket creates unmanaged exposure.
• ✅ Using an ECN broker with GBPUSD and XAUUSD spreads consistently below 1.5 pips — the 10-pip take profit target is consumed by spread at wider brokers before the trade can close profitably.
• ✅ Starting with $1,000 or more — the auto-lot sizing at 0.01 risk on $100 is documented in backtest, but the 41.30% drawdown on the XAUUSD test confirms that undercapitalized accounts hit the 10% equity stop in a single adverse session at scaled lot sizes.
• ✅ Prepared to run 90 days on demo before committing live capital — backtest modeling quality on the XAUUSD test is explicitly flagged as crude by MetaTrader; live spread and slippage behavior is unconfirmed.

Performance verified with: MT4 backtests on ICMarketsC-Demo66 (build 1440), Every Tick model (primary) and Control Points model (XAUUSD). No live account type or broker confirmed.
