Chiroptera is a Expert Advisor for MetaTrader 5, published by Rob Josephus Maria Janssen. Its linked live signal covers 2671 trades in 11 months, at a profit factor of 1.63 and a win rate of 74.05%. A win and a loss are 1.8× apart, so one loss undoes that many wins.

Chiroptera signal at a glance
The three panels from the MQL5 signal page, with the figures the marketplace itself plots. Its drawdown axis is the relative drawdown by balance — the same measure this site computes from the trade history further down. The equity figure, which counts floating losses on positions still open, is a different number and is printed beside it in the specification.

There is a free download, and it is the demo MQL5 hosts on the listing itself. It is the full algorithm, restricted to the MetaTrader 5 Strategy Tester — you can backtest it on your own broker's history for nothing. What it cannot do is trade a live or demo account. That needs the paid version.

What Chiroptera's record shows
Unbounded losses
The worst loss is 69.5× the typical one. Losses that fan out like this are the signature of a strategy with no fixed stop, though the export has no stop-loss column to confirm it directly.

How Chiroptera trades
Read off the record rather than the sales page: how long it holds, which way it leans, and what market the figures actually describe.
How long it stays in
Positions last 6.0 h on average, which makes this an intraday system whatever the listing calls it. Holding time decides how much the spread costs you and how much overnight risk you are carrying.
Which way it trades
Its 2,692 trades split 52.1% long to 47.9% short, so the result does not rest on the market having gone one way.
Spread across markets
It is listed for EURUSD, GBPUSD, USDJPY, USDCHF, AUDUSD, USDCAD. The published figures are the combined result, so a strong market can carry a weak one inside the same total.
Where the money came from
The same totals the listing publishes, divided into the numbers that say whether an edge is real and whether it would survive being run on a different account.
Money won against money lost
It won €3,691 and lost €2,246, a profit factor of 1.75. For every €1.00 it handed back it took €1.75 in gross profit.
Where the edge comes from
It wins 70.8% of the time, but its average win is only 0.7× its average loss. The edge is frequency, not size — it needs about 58% of trades to win simply to break even.
What one trade is worth
Averaged over 2,692 trades, each returned €0.54 on an account that opened at €230. That is the figure to multiply by your own trade count — not the headline growth.
Growth, per month
+1935.5% total over 11 months compounds to +31.0% a month. The monthly rate is the comparable number: a total says as much about how long an account ran as about how well it traded.
What could go wrong with Chiroptera
Every figure here is already in the record. These are the parts of it a summary table averages away.
Two drawdowns, not one
Drawdown reached 45.5% on equity and 25.3% on closed trades. The two sitting close together is what you want — it means open losses were not being parked out of sight.
The worst single trade
Its worst trade lost €59.83, 18.5× the average loss of €3.23. The account grew 3.5× over the record, which accounts for most of that spread — adjusted for it the worst loss is 5.4× the average. A tail still that long after the adjustment is the signature of a loss with no floor.
Its longest cold spell
It lost 15 trades in a row at some point. At the average loss that is about €48, or 21.1% of the €230 the account opened with. Assume it happens again, and ask whether you would still be running it on the far side.
Profit against the worst dip
It made 7.3× its deepest drawdown in total profit. Above one means the record has more than covered its own worst stretch.
What Chiroptera needs from your account
Cost and account size, against the drawdown this record already produced.
The account these figures came from
Every figure above comes from one account that opened with €230 at GlobalPrime-Trade. A different size, a different broker or different settings is a different result.
What buyers say
Counted from the reviews MQL5 publishes on the listing. We count the subjects raised and the ratings given; we do not reprint the reviews.
What the marketplace scores it
4.50 out of 5 from 54 reviews on MQL5. That is a rating of the purchase — the seller, the support, the documentation — and only indirectly of the trading.
The rating, split three ways
MQL5 scores it 4.50 on description, 4.40 on reliability and usability, and 4.50 on support. Buyers rate reliability and usability lowest, which is the part the headline number averages away.
What buyers actually write about
Across the 20 most recent reviews, results and profit comes up most often — 11 of them mention it. Losses and drawdown is the subject appearing most in the negative ones.
How the recent ones split
Of the 20 reviews the listing serves, 15 rate it four stars or better and 5 rate it two and a half or worse. This is the most recent page rather than every review ever left, which means it describes the version on sale now.
Who maintains it
How recently it was touched, how long it has been sold, and what the marketplace record says about the seller.
Whether anyone is still working on it
Version 6.92, last updated 13 Aug 2026 — about 2 months ago. A system still being touched is one whose author is still answering for it.
How long it has been on sale
Listed since 25 Oct 2025, about 12 months. Long enough to have traded through more than one kind of market.
Who is behind it
MQL5 gives Rob Josephus Maria Janssen its badges for “Sold more than 100 products”. Those count marketplace volume, not trading results — a seller can move a great many copies of something that loses money.

Chiroptera: common questions
The four things people search for about this product, answered from the record rather than from the sales page.
Is there a Chiroptera free download?
Yes — a free demo. Chiroptera is sold on the MQL5 Market, and every listing there carries a demo you can download at no cost. It is the full algorithm limited to the MetaTrader 5 Strategy Tester, so you can backtest it on your own broker history for nothing, but it will not trade a live or demo account. The full version is $29.99 from us, against $899 on the MQL5 Market. MQL5 records 4,102 downloads of it. Anything advertising the paid version as a free live download is a pirated build — usually modified, always unsupported, and a common way to lose an account.
Does Chiroptera have a live signal?
Yes. Chiroptera publishes a live signal on MQL5 covering 2,659 trades over about 11 months, and MQL5 verifies it from the broker's own trade feed rather than from the seller. It shows 31.0% a month compounded, a deepest fall of 25.3% and a profit factor of 1.75. Every figure on this page is recomputed from that record, and the page links it so you can check the arithmetic yourself.
Is there a Chiroptera backtest?
Not one from us, and deliberately. A backtest is run by whoever is selling the product, on history and settings they choose, and it can be tuned until it looks good — which is why a flawless backtest and a poor live record so often sit on the same page. Instead this page measures 2,659 real trades over about 11 months of forward results, which is stronger evidence than any backtest: nobody can re-run it until it looks good. If you want a backtest, run your own: the free MetaTrader 5 demo does exactly that on your own broker's spreads, which is the only backtest whose assumptions you control.
Is there a Chiroptera Myfxbook review?
Not that we can verify. Chiroptera is not tracked on Myfxbook, and we will not point at a third-party page we cannot confirm belongs to this product — a name match is not proof. Its verified record is the MQL5 signal linked on this page, which serves the same purpose: an independent platform reading the broker's trade feed directly rather than taking the seller's word for it. Reviews on the MQL5 listing itself rate the purchase — the seller, the support, the documentation — rather than the trading, which is what the measured figures on this page are for.
