Chiroptera EA MT5 v3.2 + Setfiles

Chiroptera EA – Multi-Currency Night-Session Trading System for MetaTrader 5

Chiroptera is an MT5 Expert Advisor built by developer Rob Josephus Maria Janssen (MQL5 handle “dutchdevil”) around quiet-hours, multi-currency trading with single trades and limit orders. The developer’s public MQL5 Signal and Myfxbook accounts show live gains ranging from +246% to +1,863%, alongside equity drawdowns of roughly 39%-50%. This store’s package delivers Chiroptera EA v3.2, an earlier build than the developer’s current v6.92 marketplace release, so treat the live proof below as evidence of the underlying strategy rather than a guarantee that this exact build replicates it.

⚡ Key Highlights

• 📈 The public MQL5 Signal “Chiroptera Global Prime” shows +1,863.12% growth over 46 weeks across 2,479 trades, with a 74.30% win rate.
• ⚙️ Trades a multi-currency portfolio during quiet overnight sessions using single trades and limit orders, per the developer’s description.
• 🛡️ The developer states Chiroptera avoids martingale and grid trading; position sizing scales through an adjustable RiskFactor input (0.5 to 3).
• ⚠️ Equity drawdown across the developer’s public live accounts ranges from roughly 39% to 50%, well above what “non-martingale” positioning might suggest.
• 🖥️ ECN, Raw, or Zero Spread execution is recommended by the developer; users report results vary meaningfully by broker.
• 📦 This package includes three ready-made risk presets (low, medium, high) alongside the core v3.2 EA file.

📊 Performance Results

The strongest available evidence is the developer’s public MQL5 Signal “Chiroptera Global Prime,” running since October 24, 2025 on a €230.11 account. Over 46 weeks it recorded +1,863.12% growth across 2,479 trades, a 74.30% win rate, a 1.70 profit factor, 25.33% balance drawdown, and 45.51% equity drawdown. Chiroptera Global Prime MQL5 Signal performance shows these figures updating live, and the page has repeatedly displayed MQL5’s own high-growth and drawdown warnings.

A second live account, “Chiroptera Hantec Markets Standard,” started May 7, 2026 on a €100 balance and shows +246.54% growth over 24 weeks across 1,052 trades, a 61.97% win rate, a 1.37 profit factor, and 49.75% equity drawdown. The matching Myfxbook Hantec Global performance record confirms nearly identical numbers on the same real EUR account. A separate public Myfxbook account on Ultima Markets shows a different profile entirely: +529.37% gain, 39.15% drawdown, 665 trades, and a 3.29 profit factor, illustrating that results shift materially by broker.

Equity drawdown near 45%-50% on two of the developer’s primary live accounts is the single most important risk figure here. It means an account can lose close to half its equity during an adverse stretch before recovering, even though the developer describes RiskFactor-based sizing and a configurable stop loss (1,300 points in the default setting). Buyers should size positions using the included low-risk preset if they cannot tolerate that level of equity swing, and should hold enough spare capital to survive a drawdown of this magnitude without a margin call. Past performance does not guarantee future results.

⚙️ How It Works

Strategy: The developer describes Chiroptera as a multi-currency EA that trades during quiet overnight or night-session hours, roughly 2-3 hours daily, using single trades and limit orders rather than continuous market activity.

Entry: An adaptive learning process ranks and allocates currency pairs based on each broker’s historical behavior. The exact entry formula and indicators are not publicly disclosed.

Position / Grid Management: The developer states Chiroptera does not use martingale or grid trading. Position sizing scales through the RiskFactor input (0.5 = safer, 1 = low, 2 = medium, 3 = high, capped at 3), or through a fixed lot size when StaticLotsize is set above zero.

Exit: Stop loss and take profit are dynamically managed, with a default StopLoss distance of 1,300 points. TemporaryRemoveStopLoss is enabled by default and removes stop-loss protection during high-spread periods such as rollover, a mechanism worth understanding before going live.

Risk Control: Built-in filters cover scheduled news, holidays, spread, slippage notification, and margin-level notification. MaxSpreadPts defaults to 0, meaning spread rejection is inactive unless configured.

Best Conditions: One chart manages the full portfolio (OneChartSetup=true). The developer recommends ECN, Raw, or Zero Spread accounts, and results have been reported to vary by broker.

Caution: TradeFridaySession and TradeFridaySessionFirstHalf are enabled by default, allowing positions to be opened or held into the weekend, which can carry weekend gap risk.

🧩 Technical Specifications

🎯 Who Should Use This EA

Ideal for:

• Traders comfortable with equity drawdowns in the 40%-50% range, as shown on the developer’s public live accounts.
• Traders who want a single-chart, multi-currency system that trades during quiet overnight hours rather than all session.
• Traders willing to test the EA on their own broker before committing full capital, given documented broker-to-broker variance.

Best results when:

• Run on an ECN, Raw, or Zero Spread account with stable overnight spreads.
• Configured with the low-risk preset and enough spare capital to absorb a large equity swing without a margin call.

Not ideal for: Traders who need low or bounded drawdown, small accounts that cannot withstand a 40%-50% equity swing, or anyone relying on the “non-martingale” description as an independently verified guarantee.
