Chiroptera is an expert advisor for MetaTrader 5 that trades forex pairs in a short window each day, mainly in the quiet hours around the daily rollover, and stays out of the market for the rest of the day. It manages a whole list of symbols from a single chart.
The EA opens single positions rather than building a ladder of orders. Each trade has a take profit and a stop loss, and the EA adjusts these while the trade is open. Entries use limit orders, which the developer says helps limit slippage and delay. The tool also tracks volume and sudden price spikes in real time, so it can stand aside when conditions change unexpectedly. It connects to a news source to check holidays and recent or upcoming announcements before it trades.
The store lists this product under grid and volume tags. The developer describes the trading itself as non-martingale and non-grid, so check the trade log in a demo test to see exactly how positions are opened on your broker.
A learning routine weights symbols by how they have performed for a given broker. In the strategy tester the first 60 days are used for learning, and only the minimum lot size is traded during that period. On a live account the EA is said to use a pre-learned file, so the wait is not needed.
The default Pairs list holds major and cross pairs such as EURUSD, GBPUSD, USDJPY and AUDCAD. You can edit the list to match the symbols and suffixes your broker uses. Because the EA runs every listed symbol from one chart, the chart timeframe is not the main driver of its behaviour. Check that every symbol is visible in Market Watch.
The inputs below are the main ones. Confirm the values in the input tab of your own copy, since defaults can differ between brokers and over time.
| Input | Purpose |
|---|---|
| Magic | Magic number so the EA can run beside other EAs on the same account |
| Run All Pairs | True trades every listed symbol from one chart; false trades only the chart symbol |
| Pairs | Semicolon-separated list of symbols to trade |
| RiskFactor | Scales average lot size with balance; a higher value means larger positions |
| StopLoss | Stop distance in points; 0 means no stop loss |
| Rollover options | Remove take profit and limit orders around rollover entry, exit or the whole window if slippage occurs; backtest before use |
| Friday session options | Allow trading in the first or second half of Friday, including holding over the weekend |
| UseLearning | Lets the EA learn lot sizes in the tester |
| UseGoldForGMTOffset | Uses gold to detect the broker's GMT offset; turn off if errors appear |
Position size depends on RiskFactor and your balance, so test a low value on a demo account first. Holding trades over a weekend, if you enable the Friday options, exposes you to gap risk. Spreads, swaps and execution around the rollover differ widely between brokers.
Trading carries risk and you can lose some or all of your capital. Backtests and past results do not predict future ones. Use a demo account first and only risk money you can afford to lose.

No. This is an MT5 expert advisor and will not load in MetaTrader 4. You need a MetaTrader 5 terminal and a broker that offers MT5 accounts.
Not by default. With Run All Pairs set to true you attach it to one chart and it trades every symbol in the Pairs list. Setting it to false limits it to the chart symbol. Make sure each listed symbol is visible in Market Watch and that its name matches your broker's naming, including any suffix.
The developer states that in the strategy tester the EA spends the first 60 days learning and trades only the minimum lot size. On a live account it is said to use a pre-learned file instead. Test over a long enough period to cover this learning phase and read the results with that in mind.
The developer says the EA uses limit orders to reduce the effect of slippage and delay, so a low-latency VPS should not be essential. You still need the terminal running during the trading window, so a stable connection or a standard VPS is a sensible choice.
Start with RiskFactor and StopLoss, as they control exposure. Then check the Friday session options and the rollover options, and backtest any change before using it live. Leave the other inputs at their defaults unless you have a specific reason to change them.
No. Trading carries risk, you can lose money, and past or backtested results do not predict future ones. Test on a demo account first.
