Frequently Asked Questions
Quick Summary:
Chiroptera for MT5 is a multi-currency night trading EA by Rob Josephus Maria Janssen that only operates during the quiet hours of the trading day. It places single trades with defined stop losses and take profits — no grid, no martingale. An advanced adaptive learning algorithm continuously optimises pair allocation based on real performance on your specific broker.
The standout feature: four verified MQL5 live signals running simultaneously on four different brokers — VT Markets, Star Trader, Titan FX, and Global Prime — all showing substantial growth over 24 weeks with real withdrawals taken and zero suspicious deposits added. This level of cross-broker verification is rare in the EA market.

Why Night Trading?
Most retail traders lose money during the London and New York sessions — the busiest, most volatile, and most unpredictable hours of the trading day. News releases, institutional order flow, geopolitical tweets, and algorithmic bursts create an environment where retail EAs get chopped up.
Chiroptera avoids all of that. It only trades for 2–3 hours per day during the quiet Asian session hours — when spreads are tighter, volatility is lower, and price movements are more predictable. Outside of these hours, your capital sits safely with the broker, completely out of the market.
This isn’t just risk reduction — it’s a fundamentally different approach to when and how an EA should operate. The quiet hours offer genuine statistical edges that disappear during volatile sessions.
Four Live Signals — Four Brokers — Zero Suspicious Deposits
This is where Chiroptera separates itself from virtually every other EA on the market. The developer runs four simultaneous live signals on four completely different brokers, all publicly trackable on MQL5:
✅ Four Verified Live Signals — All 24 Weeks, All With Withdrawals
| Broker | Growth | Max DD | Win Rate | Deposit | Withdrawn | Profit |
|---|---|---|---|---|---|---|
| VT Markets | 935% | 39.5% | 77.7% | €242 | €653 | €727 |
| Star Trader | 897% | 49% | 78.9% | €250 | €570 | €707 |
| Titan FX | 614% | 36.4% | 75.6% | €250 | €510 | €697 |
| Global Prime | 265% | 42.1% | 73.9% | €230 | €270 | €356 |
All signals: 24 weeks running, 99% algo trading, 1:500 leverage. Deposits column shows initial deposit only — zero additional deposits on any account. Withdrawals confirm real money taken out.
Why this matters: Most EA developers show a single live signal — often on a carefully chosen broker with optimal conditions. Running four simultaneous signals on four independent brokers eliminates cherry-picking. The results vary by broker (265% to 935%), which is honest and expected — execution conditions differ. But all four are profitable with withdrawals taken. This is the most transparent live validation we’ve seen on any EA.
The withdrawal column is key: Every signal shows money withdrawn — €270 to €653. There are zero additional deposits after the initial funding. This means the developer isn’t topping up accounts to mask drawdowns. What you see is genuine trading performance.
The Adaptive Learning Algorithm
Chiroptera’s most distinctive technical feature is its adaptive learning algorithm. Rather than using fixed lot sizes across all currency pairs, the EA continuously evaluates which pairs perform best on your specific broker and adjusts allocation accordingly.
The process works in two phases:
- Learning Phase (first 60 days by default) — the EA trades all configured pairs equally while observing performance metrics. It uses time-exponentially weighted evaluation, meaning recent performance counts more heavily than older results
- Learned Phase — after the learning period, the EA adjusts lot sizes per pair based on observed performance. Pairs that perform well get larger allocations; underperformers get reduced. This allocation continues to adapt as new data comes in
The backtest clearly shows this: the equity curve is relatively flat during the learning phase, then accelerates dramatically once learned parameters are applied. This is not curve-fitting — it’s a genuine adaptive system that learns your broker’s specific execution characteristics.
You can also “kickstart” a live account by generating learned weights in the Strategy Tester and importing them, skipping the live learning period.
How Chiroptera Trades
The EA’s approach is methodical:
- Timing: Trades only during the quiet Asian session hours — approximately 2–3 hours per day. Outside these hours, no positions are open. Your capital is out of the market ~90% of the time
- Execution: Uses limit orders (not market orders) to prevent slippage and execution delays. The EA modulates the broker’s price feed to ensure optimal limit order placement regardless of spread
- Position Sizing: Single trades per pair — one position at a time, no stacking, no averaging. Stop loss and take profit are set from entry and continuously adjusted to maximise gains and minimise losses
- Pairs: Up to 20 currency pairs from a single chart attachment (one-chart setup). Includes majors, crosses, and JPY/CHF pairs. An optional “BestPairs” mode runs only the top 5 performers
- Protection: Real-time volume spike detection, news blocking (past and future), holiday blocking, trend filtering, swap-to-profit ratio checks, and configurable maximum spread filter
Backtest: $10K → $5.3M (Jan 2025 – Mar 2026)
✅ Backtest — January 2025 to March 2026
- Initial Balance: $10,000
- Final Balance: $5,317,372
- Profit Factor: 4.12
- Max Balance Drawdown: 6.68%
- Period: 14 months (includes ~60-day learning phase)
- Note: The flat early section is the adaptive learning phase — the EA is observing performance before adjusting allocations
Past performance is not indicative of future results. The backtest includes the adaptive learning phase. Always test on demo before going live.
Protection Systems
Chiroptera includes more protection layers than most EAs we’ve reviewed:
- News Filter — connects to a live news server to monitor past and upcoming news events. Blocks trading when high-impact events (e.g. interest rate decisions) create excessive volatility
- Holiday Filter — blocks trading during NYSE holidays when liquidity is thin
- Volume Spike Detection — monitors real-time volume for sudden shocks (e.g. tariff announcements, geopolitical tweets). Prevents entries during ad-hoc volatility events
- Trend Filter — prevents placing trades on the wrong side of short-term trends that are expected to retrace against the position
- H1 Bollinger Band Filter — avoids entries on the far side of temporary momentum that’s expected to reverse
- Swap Check — prevents trading if overnight swap cost would exceed a configurable ratio of the maximum obtainable profit
- Weekend Gap Protection — prevents trading immediately after weekends if the gap is too large
- Daily Loss Limit — closes all positions and orders when the configured maximum daily loss percentage is breached (prop firm compatible)
- Temporary SL Removal — optionally removes stop loss during high-spread periods (typically the hour after rollover) to prevent unnecessary triggering from temporary spread widening

Our Assessment
Based on four live signals, backtest, reviews, and system architecture:
- Live Signal Verification — Best We’ve Seen: Four simultaneous live signals on four independent brokers — VT Markets, Star Trader, Titan FX, and Global Prime — is unprecedented transparency. All four show real withdrawals and zero additional deposits. This eliminates cherry-picking, deposit-masking, and single-broker luck. The performance variation (265% to 935%) is honest and expected — it shows the EA is genuinely sensitive to execution conditions rather than faking uniform results
- Night Trading Logic: The quiet-hours approach is a legitimate statistical edge. Asian session scalping exploits lower volatility and tighter spreads during hours when most retail EAs aren’t active. Keeping capital out of the market ~90% of the time dramatically reduces exposure to news shocks, flash crashes, and session-open volatility
- Adaptive Learning: The exponentially-weighted pair allocation algorithm is genuinely sophisticated. Rather than forcing all pairs equally, the EA learns which pairs work best on your specific broker. The backtest clearly shows the learning → performance transition. The ability to import learned weights from backtesting into live is a practical feature that reduces the live learning period
- Single Trade Architecture: No grid, no martingale, no position stacking. One trade per pair at a time with defined risk. Limit orders prevent slippage. This is the cleanest execution model possible
- Protection Depth: News server connection, holiday blocking, volume spike detection, trend filtering, swap ratio checks, weekend gap protection, and daily loss limits. This is the most comprehensive protection suite we’ve seen on any EA — especially the real-time volume spike detection for ad-hoc events like tariff tweets
- Drawdown Reality: The live signals show 36–49% maximum drawdowns. These are significant numbers. The 6.68% backtest drawdown is much lower because it uses optimised conditions — live drawdowns are the numbers to plan around. Size your account for 40–50% potential drawdown at the risk settings used on the live signals
- Overall: Chiroptera is one of the most transparently validated EAs available. The four-broker live signal approach, clean single-trade architecture, adaptive learning, night-only trading, and comprehensive protections create a system that stands out on engineering quality alone. The developer clearly understands execution, risk, and broker dynamics at an institutional level. The main considerations are the significant live drawdowns (36–49%) and the 60-day learning period before optimal performance. For serious traders who want a multi-currency night scalper with unmatched live verification, Chiroptera is a top-tier choice
Who Is Chiroptera For?
Ideal for traders who:
- Want verified multi-broker live results — four signals on four brokers is unmatched transparency
- Prefer minimal market exposure — capital is out of the market ~90% of the time
- Value adaptive intelligence — the EA learns which pairs work best on your broker
- Need prop firm compatibility — built-in daily loss limits and single-trade architecture
- Want multi-currency diversification — up to 20 pairs from a single chart
Consider alternatives if you:
- Can’t accept 40–50% potential drawdown — live signals show 36–49% max DD
- Want immediate full performance — the 60-day learning period means slower initial results
- Prefer MT4 — this is MT5 only
- Want Gold or commodity trading — Chiroptera trades forex pairs only
- Don’t have VPS access — mandatory for limit order execution
Risk Disclaimer
Past performance does not guarantee future results. The four live signals show 24 weeks of trading with drawdowns ranging from 36% to 49%. Night scalping strategies are sensitive to broker execution conditions, spread behaviour, and liquidity during quiet hours. The adaptive learning algorithm requires approximately 60 days to optimise — initial performance may be subdued. Results vary significantly by broker (265% to 935% across four brokers). Always test on a demo account with your broker before live deployment. Do not trade with funds you cannot afford to lose.

FAQs
What is Chiroptera EA?
Chiroptera is a multi-currency night trading EA for MetaTrader 5 by Rob Josephus Maria Janssen. It trades during the quiet Asian session hours (2–3 hours/day) using single trades with limit orders — no grid, no martingale. An adaptive learning algorithm optimises pair allocation based on real performance on your specific broker. Four verified MQL5 live signals run on four different brokers showing 265% to 935% growth over 24 weeks.
Why does it only trade at night?
The quiet Asian session hours offer lower volatility, tighter spreads, and more predictable price movements compared to the London and New York sessions. By only trading during these hours, Chiroptera exploits a genuine statistical edge while keeping capital out of the market approximately 90% of the time. This dramatically reduces exposure to news events, flash crashes, and session-open volatility.
What are the four live signals?
The developer runs four simultaneous verified MQL5 live signals on four independent brokers: VT Markets (935% growth, 39.5% DD), Star Trader (897%, 49% DD), Titan FX (614%, 36.4% DD), and Global Prime (265%, 42.1% DD). All have been running for 24 weeks with real withdrawals taken and zero additional deposits. This cross-broker verification eliminates cherry-picking and demonstrates genuine performance across different execution environments.
Why do results vary so much between brokers (265% to 935%)?
Night scalping strategies are particularly sensitive to broker execution conditions — spread behaviour during quiet hours, swap rates, slippage on limit orders, and liquidity availability vary significantly between brokers. The adaptive learning algorithm adjusts to each broker’s characteristics, but the underlying conditions create different outcomes. This variation is honest and expected — uniform results across brokers would actually be more suspicious.
How does the adaptive learning algorithm work?
The EA runs a 60-day learning phase (configurable) where it trades all configured pairs equally while observing performance. It uses time-exponentially weighted evaluation, meaning recent performance counts more than older data. After the learning period, it adjusts lot sizes per pair — better-performing pairs get larger allocations, underperformers get reduced. The learning continues adapting as new data comes in. You can also generate learned weights in the Strategy Tester and import them to kickstart a live account.
Does it use grid or martingale?
No. Chiroptera places single trades per pair — one position at a time with defined stop loss and take profit. No stacking, no averaging, no lot multiplication. It uses limit orders (not market orders) to prevent slippage and ensure precise entry execution. This is the cleanest trade architecture possible.
What currency pairs does it trade?
Up to 20 pairs: EURUSD, GBPUSD, AUDCAD, EURAUD, EURCAD, GBPAUD, GBPCAD, EURCHF, GBPCHF, USDJPY, EURJPY, USDCAD, EURGBP, USDCHF, CADCHF, CHFJPY, AUDJPY, AUDCHF, AUDUSD, GBPJPY. There’s also a “BestPairs” mode that runs only the top 5: CHFJPY, EURJPY, GBPAUD, GBPJPY, EURAUD. The adaptive algorithm determines optimal allocation across whichever pairs you configure.
Is it prop firm compatible?
Yes. The EA includes a configurable MaxDailyLossPercentage parameter that closes all positions and orders when breached. Single-trade architecture (no grid, no stacking), short market exposure (2–3 hours/day), and defined stop losses align with most prop firm rules. The developer explicitly markets Chiroptera as “Prop Firm Ready.”
What about the drawdowns on the live signals (36–49%)?
These are significant and should be factored into your risk planning. The backtest shows 6.68% balance drawdown, but live conditions always produce higher drawdowns than backtests. Plan for 40–50% potential drawdown at the risk settings used on the live signals (RiskFactor 5.0). You can reduce the RiskFactor to lower drawdown proportionally — the trade-off is proportionally lower returns.
What is the learning period and can I skip it?
The default learning period is 60 days, during which the EA trades all pairs equally while gathering performance data. Initial results during this phase will be modest. You can skip the live learning period by generating learned weights in the Strategy Tester (using ReadOrWriteWeights) and importing them into your live account. This “kickstarts” the adaptive algorithm with pre-learned broker-specific parameters.
What news and event protection does it have?
The EA connects to a live news server to monitor upcoming and past news events. It blocks trading during high-impact events like interest rate decisions, NYSE holidays (thin liquidity), and detects real-time volume spikes from ad-hoc events like geopolitical announcements or tariff tweets. Weekend gap protection prevents trading after large gaps. This is the most comprehensive event-protection system we’ve seen on any EA.
Do I need a VPS?
Yes — required, not optional. The EA uses limit orders that need to be placed with precise timing during the night session. Connection drops, PC sleep mode, or execution delays can prevent orders from being placed or managed correctly. A VPS ensures 24/5 uptime with low latency.
What timeframe do I use?
Any timeframe — it’s irrelevant. Chiroptera manages its own internal timing and doesn’t use chart timeframe data. Simply attach it to any chart (e.g. EURUSD) with OneChartSetup enabled and it will trade all configured pairs from that single chart attachment.
What broker should I use?
The developer provides live signals on VT Markets, Star Trader, Titan FX, and Global Prime — all are confirmed to work. Performance varies by broker due to execution conditions. The adaptive learning algorithm will optimise for whichever broker you choose. Low-spread accounts with good overnight session liquidity will produce the best results.
Who is the developer?
Rob Josephus Maria Janssen, based in the Netherlands. His approach is distinctly engineering-focused — the EA’s design reflects deep understanding of execution mechanics, broker microstructure, and statistical learning. The level of detail in the input parameters (swap-to-profit ratios, volume spike sigma, H1 Bollinger filters) and the four-broker live signal approach suggest a developer who treats trading as a quantitative engineering problem rather than a marketing exercise.
What does the backtest show?
January 2025 to March 2026: $10,000 → $5,317,372 with a 4.12 profit factor and 6.68% maximum balance drawdown. The equity curve clearly shows the adaptive learning phase (flat early section) followed by accelerating growth once learned parameters are applied. The backtest drawdown (6.68%) is significantly lower than live drawdowns (36–49%), which is normal — always plan around live numbers, not backtest numbers.
How long should I demo test before going live?
At minimum 60 days — the length of the adaptive learning phase. The EA won’t be operating at full capability until it has learned the optimal pair allocation for your broker. You can shorten this by importing learned weights from a backtest. After the learning phase, observe another 30+ days to evaluate performance. The developer’s four live signals provide ongoing reference benchmarks.
