Chiroptera Review
Night scalper on 28 pairs, explicitly without grid or martingale, single trades with SL (1,300 points) and limit orders against slippage. The track is real and active (2,485 trades in 47 weeks), but 45.5% equity drawdown and growth computed from a €230 deposit and €3,598 of withdrawals. Night scalping lives or dies with the broker — reviews report account closures. Yellow.

What Chiroptera is
Chiroptera by Rob Josephus Maria Janssen is a scalping EA on EURUSD, GBPUSD, AUDCAD, AUDNZD (MT5), sold via MQL5-Market. We classify it independently — by strategy risk, verified live track, transparency and value, not by vendor promises.
Live results & track record
MQL5-Signal seit 47 Wochen bei Global Prime (gelesen 01.09.2026): 2.485 Trades, 53 pro Woche bei 6 h Haltedauer, max. Drawdown 45,5 % nach Equity (25,3 % nach Balance), Depotauslastung bis 73,6 %. Die +1.885 % sind durchgespült: 230 € Ersteinlage, 2.719 € Einzahlungen, 3.598 € Auszahlungen. The vendor runs one public account for it (329 days), which we read ourselves — the account type (real or demo) is in the table below. Its most telling account shows +1.885 % at a maximum floating loss of -45,5 % (Global Prime). That is real money, not a polished backtest.
Strategy & risk
The scalping approach sets the risk profile. The approach uses defined entries/exits; what matters is whether the live track confirms the backtest picture. The measured floating loss of up to 45.5 % underlines that — only run with a buffer. On MQL5 you buy the vendor setting — a hard risk cap (parameters or an external drawdown guard) is on you to set.
Cost & usability
On MQL5 the EA costs 899 $. You buy the vendor version without calibration — risk cap, broker choice and setfile are on you.
Who it is (not) for
Suitable for traders who accept a documented live track and run the EA with their own hard risk cap and budget it as *one* building block. Not suitable for small accounts without a buffer, given the floating loss of up to 45.5 %, or for anyone who mistakes a smooth backtest curve for a guarantee.
Verdict
Chiroptera lands at 3.2/5 — with reservations. The verified ATS live track is the strongest argument.
Vendor’s public accounts
Accounts the vendor publicly links himself (Myfxbook or MQL5 signal) and that we read ourselves on the reference date — not his marketing figures. The "Account" column says whether it is real money or a demo account. For Myfxbook accounts the floating-loss column shows the platform’s maximum drawdown.
