Chiroptera MT5 v3.2 + SetFiles: No DLL – Build 5833+

Chiroptera MT5

Night scalping EAs on MT5 often rely on martingale or grid recovery to mask losing trades. Chiroptera MT5 takes a different path. It is a MetaTrader 5 Expert Advisor developed by Rob Josephus Maria Janssen that runs on up to 28 currency pairs during the quietest market hours. According to the vendor’s MQL5 product page and verified Myfxbook tracking, the EA is built around a non-martingale single-trade night scalping strategy with adaptive learning that calibrates position sizing to your specific broker over the first 60 days. It is aimed at traders who want multi-broker verified live signals, use an ECN broker with tight rollover spreads, and can tolerate drawdowns approaching 40-50%.

When researching Chiroptera MT5, the most striking finding was the number of independently verified live signals running across different brokers simultaneously. The primary Myfxbook account labeled “Chiroptera EA Star Trader” under user dutchdevil shows a +3,648.58% gain with a 38.02% drawdown. The account has generated a profit of €1,433.63 with €1,783.63 in withdrawals against €350 in deposits, meaning the trader has already recovered more than five times the initial capital while keeping the system running.

According to AlgoCheck’s independent review, Chiroptera falls into the “Stop discipline observed” risk class at “Established” maturity, with a largest measured drawdown of -45.5%. The review also notes the largest loss the build allows is not verifiable and flags four red flags related to hidden risk patterns. This is a relevant counterpoint to the strong headline gains across the Myfxbook accounts.

Key Features

Chiroptera MT5 is built as an adaptive night scalping system for MetaTrader 5. Based on vendor documentation, verified tracking data, and independent reviews, here are the features that stand out:

• Adaptive Learning Algorithm: The EA uses a time-exponentially weighted machine learning algorithm that monitors which currency pairs perform best on your specific broker during the first 60 days and dynamically adjusts position sizing to allocate more capital to higher-performing pairs.

• Non-Martingale, Non-Grid Architecture: The vendor states Chiroptera places single trades only, without martingale, grid, or any other mathematically guaranteed-to-fail methods. Each trade has a tactically placed take-profit and stop-loss.

• Multi-Currency Coverage: The EA trades up to 28 currency pairs from a single chart, with default pairs including EURUSD, GBPUSD, AUDCAD, AUDNZD, EURAUD, EURCAD, GBPAUD, GBPCAD, EURCHF, GBPCHF, USDJPY, EURJPY, USDCAD, EURGBP, USDCHF, CADCHF, CHFJPY, AUDJPY, AUDCHF, AUDUSD, and GBPJPY.

• Extended Filtering: The EA connects to a live news server that monitors holidays and news impacts using advanced Pearson correlation calculations for future news pattern impacts, and carefully measures real-time volatility to prevent impacts from ad-hoc events.

• Real-Time Push Notifications: Users receive real-time performance notifications on the MT5 Mobile App, allowing monitoring of slippage and margin levels without being at the terminal.

• Prop Firm Ready: The vendor explicitly states Chiroptera is Prop Firm Ready, with a MaxDailyLossPercentage setting for prop firm rules and hard stops on every trade.

• Limit Order Execution: The EA places limit orders to prevent slippage and execution delays, negating the need for a low-latency VPS.

• Detailed Baretail Logging: The system prints detailed performance metrics in Baretail for in-depth evaluations during backtest and live trading.

Why Should You Buy This?

• Verified Multi-Broker Live Tracking: Unlike many EAs that show only a single vendor-controlled signal, Chiroptera has multiple independently tracked Myfxbook accounts running simultaneously across different brokers, giving buyers raw data to evaluate from multiple sources.

• Adaptive Broker Calibration: The EA’s 60-day learning period means it custom-tunes position sizing to your specific broker’s execution environment, spreads, and liquidity – a level of personalization that most night scalpers lack.

• Non-Martingale Architecture: The single-trade, stop-loss-per-trade design means the system does not hide risk in grid recovery baskets or martingale multipliers. Losses are visible and contained at the individual trade level.

• Flexible Risk Scaling: The RiskFactor parameter allows users to scale exposure from 0.5 (safe) through 1.0 (moderate) up to 3.0 (high), with the vendor capping the maximum at 3 to prevent over-leveraging.

• Broad Currency Coverage: Trading up to 28 pairs from one chart provides diversified exposure across major, minor, and cross pairs without requiring multiple chart setups.

• Who This Is Not For: Chiroptera is not suitable for traders who cannot tolerate drawdowns approaching 40-50%. The vendor explicitly recommends against using settings that generate more than 25% profit per month, and independent analysis notes the largest measured drawdown at -45.5%. Some brokers have reportedly restricted accounts using this EA due to its trading style, so checking broker compatibility before purchase is essential.

Why Chiroptera MT5 Is Different

Most night scalpers on the market follow an identical template: trade the Asian session, scalp a few pips on mean reversion, and treat every broker and every currency pair the same. Chiroptera MT5 breaks from this pattern in a meaningful way. According to the vendor, the EA’s adaptive learning algorithm reads historical trade data and uses an exponentially time-weighted filter to learn which pairs perform best on your specific broker, then dynamically adjusts position sizing to allocate more capital to the pairs that are working. This is not marketing language – the developer publishes the full input parameter documentation on MQL5 including the adaptive lookback windows, weighting methods, and convergence mechanics.

The non-martingale, single-trade architecture is another differentiator. While many competing EAs hide risk in grid recovery baskets or martingale multipliers, Chiroptera places hard stop-losses on every trade. The developer also maintains four simultaneous live signals on four different brokers, which is almost unheard of in the EA marketplace. This multi-broker verification approach provides a level of transparency that most vendors do not offer, though community reviews note that the aggressive profit targets across these signals have drawn criticism from some traders who expected more consistent results.

Chiroptera MT5 Strategy & Logic

Based on vendor documentation and the verified trade history, here is how Chiroptera MT5 operates in practice:

• Night Session Trading: The EA is actively trading for only 2-3 hours per day during the quietest market hours, keeping client assets out of the market during the busiest and most unpredictable times of day.

• Market Scan: Before each session, the EA reads historical trade data and applies its time-exponentially weighted adaptive learning algorithm to identify which pairs are currently performing best on the specific broker.

• Entry Trigger: The system places limit orders to prevent slippage and execution delays. It modulates the incoming broker price feed to ensure optimal limit order placement independent of broker spread.

• Trade Management: Each trade is placed with a tactical take-profit and stop-loss. The average hold time observed on verified signals is approximately 8 hours, indicating an intraday to short-term approach.

• Exit Conditions: Trades are closed when the take-profit or stop-loss is reached. A temporary stop-loss removal feature prevents unnecessary triggering during high-spread periods, typically the hour after rollover.

Built-in Risk Controls (as documented by the vendor):

• RiskFactor Scaling: Average lot size is calculated as RiskFactor multiplied by balance in USD divided by contract size. Risk 0.5-1.0 is considered safe, Risk 2 is medium, and Risk 3 is high, with the maximum capped at 3.

• Max Spread Filter: Prevents symbols from trading when the maximum spread is violated, which is important for night scalping where spreads can widen significantly.

• Min Profit to Swap Ratio: Ensures the maximum profit of each trade is at least 5 times the swap cost, protecting against holding trades over rollover that don’t justify the financing cost.

• Margin Level Notification: Sends notifications to the MT5 Mobile App if margin level drops below 100%.

• Slippage Notifications: Alerts the user if negative slippage on entry or exit exceeds the configured threshold (default 20 points).

• MaxDailyLossPercentage: A prop-firm-compatible setting that caps daily losses, particularly relevant for traders using funded accounts.

• Instant Stop-Loss Placement: An optional setting for brokers or prop firms that require a stop-loss to be placed at the moment a limit order is triggered, rather than the default placement based on actual entry level within 10-20 milliseconds.

Risk Disclaimer: Trading foreign exchange carries a high level of risk and may not be suitable for all investors. Leverage creates additional risk and loss exposure. Past performance, including all Myfxbook-tracked and MQL5-verified results referenced in this review, is not indicative of future results. The verified accounts show drawdowns ranging from 38% to nearly 50%, and independent analysis reports a largest measured drawdown of -45.5%. You could lose some or all of your initial investment. Do not invest money you cannot afford to lose. This review is for informational purposes only and does not constitute financial advice.

Optimized Settings Table

Note: The vendor explicitly states that for consistent growth, users should not use settings that generate more than 25% profit per month. The RiskFactor parameter should be set between 0.5 and 1.0 for safe operation, with 2 considered medium risk and 3 considered high risk. Broker compatibility is critical – the EA requires tight spreads around rollover, and some brokers have reportedly restricted accounts using this EA.

Is Chiroptera MT5 Worth It?

Chiroptera MT5 is an adaptive night scalper with a genuinely differentiated architecture: non-martingale single trades, a machine learning engine that calibrates to your specific broker, and multi-broker live signal verification. The verified Myfxbook accounts show gains ranging from +183.94% to +3,648.58%, and the primary tracked account has already withdrawn more than five times its initial deposit. For traders who want a night scalping system with transparent mechanics and broker-adaptive position sizing, Chiroptera presents a compelling option.

However, the system is not without significant risks. The verified accounts show drawdowns between 38% and 49.8%, and independent analysis reports a largest measured drawdown of -45.5% with four flagged risk patterns. Some brokers have reportedly restricted accounts using this EA due to its trading style, and broker compatibility is critical to performance. The vendor’s own guidance to avoid settings generating more than 25% monthly profit suggests the aggressive configurations that produce the highest headline gains also carry the most risk.

This EA suits experienced traders who understand night scalping mechanics, use an ECN broker with tight rollover spreads, and can tolerate drawdowns approaching 50%. Before committing, review the Myfxbook and MQL5 signal data yourself, start with a demo account, and contact the developer directly for broker recommendations.
