Nairobi is an expert advisor for MetaTrader 4 that trades from a combination of Bollinger Bands and a moving average. It also includes its own money management tools: virtual stop levels, several trailing stop methods and a choice between a fixed lot and a lot based on a percentage of risk.
The entry logic relies on two standard indicators. Bollinger Bands describe how far price has moved relative to its recent volatility, and the moving average describes the direction or average level of price. The EA looks at how price relates to both and opens a trade when its conditions are met. Each indicator can be given its own timeframe, so you can, for example, read the bands on the chart timeframe and the average on a higher one.
The EA can evaluate signals on closed candles or on the candle still forming. Using closed candles generally gives fewer and more stable signals, while the current candle reacts faster but a signal can disappear before the bar closes. Test both modes before choosing.
Virtual levels depend on the terminal staying connected and running. If MT4 closes or loses its connection, those levels are not active. Consider this if you plan to run it unattended.
The suggested configuration is EURUSD on the M5 chart. The EA may be attached to other symbols, but spreads, volatility and trading hours differ, so each symbol needs its own testing and probably its own settings.
Input names can differ, so open the properties window after attaching the EA and read each field. In general you should find the following groups.
| Group | What to check |
|---|---|
| Bollinger Bands | Period, deviation and timeframe |
| Moving average | Period, method and timeframe |
| Signal mode | Closed candle or current candle |
| Lot size | Fixed lot or percent-risk lot |
| Stop loss and take profit | Virtual levels and distances |
| Trailing stop | Type and step values |
Default values are a starting point only. Check how many positions the EA may hold at the same time and what the maximum exposure could be on your account.
Trading carries risk, and you can lose some or all of your deposit. Past or backtested results do not predict future ones. Run Nairobi on a demo account first and only risk money you can afford to lose.
Before using real money, run a backtest with good quality tick data, then forward test on a demo account with your own broker.

This listing is the MetaTrader 4 build and will only run in MT4. An MT5 terminal cannot load it. If you use MT5, you need a separate MT5 product.
The suggested setup is EURUSD on the M5 chart. The EA can be attached to other symbols, but you should test each one in the Strategy Tester and on a demo account before using real money.
In MT4 choose File, then Open Data Folder, and copy the EA file into MQL4/Experts. Restart the terminal or refresh the Navigator, drag Nairobi onto a chart, and make sure Algo Trading is switched on and automated trading is allowed in the EA properties.
Yes. The EA offers either a fixed lot size or a lot calculated from a percentage of risk. Check the exact input names and how the risk is measured in the settings window before you start.
It should run on any MT4 broker, but spreads, commissions, execution speed and stop level rules affect results. An ECN or low-spread account is usually better for a short-timeframe strategy. Test on a demo account with your broker first.
No result can be promised. Trading carries risk, and past or tested results do not predict future ones. Treat any backtest as an illustration only.
