Hidden Gem is an automated expert advisor for MetaTrader 4. It is built to trade a small group of liquid markets, mainly US and German indices, gold and a few forex pairs, on the 15-minute chart.
The author describes the logic as a multi-indicator model that reads price data and looks for entries, then places a protective stop-loss on every position. The description says it keeps to one open trade at a time and does not use martingale or hedging. The store has listed it under the grid tag, so treat that point as something to verify yourself. Run it in the Strategy Tester and then on a demo account, and look at how many orders it opens and how lot sizes change after a loss.
The author also mentions a session filter that is meant to stay out of the market around news releases and gaps. How strict that filter is, and what times it uses, depends on the inputs, so read them before you attach the expert to a chart.
Broker symbol names, spreads, swap and trading hours vary. A symbol that works in one account may need a different name or may be unavailable in another, so check this before you start.
The author says the default settings are intended to work with little configuration. The exact input names and values are not listed here, so open the input tab after attaching the expert and review each field. These are the areas worth checking:
| Area | What to check |
|---|---|
| Risk per trade | The percentage of balance risked. The author suggests one to three percent; a lower value is more cautious. |
| Stop-loss | Confirm that it is applied and see how far it sits from entry on your symbol. |
| Session or news filter | Check which hours are traded and whether the times match your broker's server time. |
| Magic number | Use a different number for each chart if you run several symbols. |
Automated trading can lose money, and leverage increases that risk. Review the stop-loss distance and the lot size on each symbol, and keep in mind that spread and slippage on indices and gold can change results compared with a backtest.
Trading carries risk, and past results, whether backtested or live, do not predict future ones. Test on a demo account first and only trade with money you can afford to lose.
For continuous operation, many users run MT4 on a VPS so that the terminal stays connected and the expert is not interrupted by computer restarts.

It is built for MetaTrader 4 and is delivered as an EX4 file. It will not run on MetaTrader 5, so check which platform your broker account uses before buying.
The store tag and the author's own description do not fully agree. The author states that it opens one trade at a time, with no martingale and no hedging. Before using real money, run it in the Strategy Tester and on a demo account, and watch how many positions it opens and how it sizes them.
The author recommends the 15-minute chart and lists US indices, GER40, gold, EURUSD and GBPJPY as suitable instruments. Symbol names differ between brokers, for example suffixes or different index names, so confirm the exact names on your account and test each one.
Extract the downloaded archive, copy the EX4 file into the MQL4/Experts folder through File, Open Data Folder in MT4, then restart the terminal or refresh the Navigator. Drag the expert onto an M15 chart and tick Allow live trading in the properties window.
The author says risk per trade is customisable and suggests a range of one to three percent. Check the input list in the expert's properties and begin at the low end, or lower, while you learn how it behaves on your broker's feed.
No. Any automated system can lose money. Backtest figures depend on the data and settings used, and past results do not predict future ones.
