Spectrum Catcher is an MT5 expert advisor that trades the spread between statistically linked symbols. It uses an ADF stationarity test and a z-score to decide when a spread is stretched enough for a mean-reversion entry.

Spectrum Catcher is an expert advisor for MetaTrader 5 that trades the gap between two related instruments rather than the direction of one market. It only acts when a statistical test says the relationship is stable and the gap has stretched far from its usual level.
The core idea is cointegration. Two symbols are cointegrated when a weighted difference between their prices, called the spread, tends to return to a steady average. The EA builds that spread using a hedge ratio and then checks whether it behaves in a mean-reverting way.
The check is an Augmented Dickey-Fuller (ADF) test. If the test suggests the spread is stationary, the pair is treated as eligible. If the link looks weak or broken, the EA stays out of the market instead of forcing a trade.
For eligible pairs, the EA calculates a z-score, which measures how many standard deviations the current spread sits from its recent mean. Values near zero are ordinary. Large positive or negative values suggest one leg is expensive relative to the other. At those stretched levels the EA opens offsetting positions, buying the cheaper leg and selling the dearer one, and it looks to close them as the z-score moves back toward zero.
The tool is designed to be attached to one EURUSD chart on the M30 timeframe. It works as a single-chart manager, so you do not need to open a chart for every symbol involved. Make sure the related symbols are available in your broker's Market Watch.
Exact input names and default values can differ between builds, so read the input tab in MT5 and any instructions that come with the download. The planning figures below are the author's general suggestions for the setup.
| Item | Suggested value |
|---|---|
| Chart | EURUSD |
| Timeframe | M30 |
| Starting balance | About 300 USD or more |
| Leverage | 1:33 or higher |
| Broker | Low spreads, fast execution |
Lot sizing, z-score thresholds and look-back lengths should be checked in the inputs before you run it on a live account.
Mean reversion only works while the statistical link holds. A relationship that looked stable can break, and a spread can keep widening for longer than expected. Spreads, commissions and swaps also affect paired trades, so test with your own broker conditions.
Trading carries risk, and past results do not predict future ones. Test on a demo account first and only trade with money you can afford to lose.
Before going live, run it on a demo account and compare behaviour with your broker's spreads and execution speed.

It is built for MetaTrader 5 only. It will not load on MetaTrader 4, so check that your broker offers an MT5 account before buying.
The tool is designed to be attached to a single EURUSD chart on the M30 timeframe. From that one chart it manages its trading logic, so you do not need to open a separate chart for each symbol. Confirm any other symbols it uses are visible in your Market Watch.
Copy the downloaded expert advisor file into the MQL5/Experts folder via File, Open Data Folder in MT5. Restart the terminal or refresh the Navigator, drag the EA onto the EURUSD M30 chart, and enable Algo Trading. Tick the option to allow automated trading in the properties window if prompted.
The author suggests a balance of about 300 USD or more and leverage of 1:33 or higher, with a broker that offers tight spreads and dependable execution. These are planning guides, not guarantees of any outcome. Check contract sizes, margin requirements and hedging support with your own broker.
It may be possible, but funded accounts often have strict drawdown, daily loss and trading-activity rules. Review the input settings against your firm's rules and test on a demo account first before using it on a funded account.
Exact input names and default values depend on the build you download, so read the input tab in MT5 and any included instructions. Start with defaults on a demo account and change one input at a time while you observe the results.
