EA Gold Harvester is a fully automated expert advisor for MetaTrader 5, built mainly for gold (XAUUSD). It combines a Bollinger Band reading of the market with a grid of orders, and it shows its working directly on the chart.
The EA looks at where price sits relative to the Bollinger Bands to judge whether the market is trending or moving in a range. When conditions suit the logic, it places a layered grid of orders at set distances. Each position has a take-profit target, and the EA tidies up leftover orders and closes positions according to its own rules.
Because the strategy is tagged for trend and breakout conditions as well as grids, the Bollinger reading is used to decide when a grid should start, pause or stop, and when a move beyond the bands should be treated differently from ordinary range movement. Check how it behaves around strong moves in your own tests, as this is where grid systems are most exposed.
The primary target is XAUUSD. A range of M15 to H1 is a sensible place to begin, but volatility, spreads and swap differ between brokers, so test on the account type you plan to use. Other symbols can be attached, but they need their own testing and parameter choices.
Exact default values can differ, so read the input list in the terminal when you load the EA. The main groups of inputs to look at are shown below.
| Input group | What to check | |
|---|---|---|
| Bollinger Bands | Period, deviation and price source used for the trend reading | |
| Grid | Number of levels and spacing between them | |
| Take profit | Distance in points for each position or for the basket | |
| Lot size | Fixed or risk-based sizing, and the largest total exposure | |
| Protection | Drawdown limit, margin checks, volatility filter and emergency close |
Grid strategies can build up several open positions when price keeps moving in one direction, which raises margin use and potential loss. Set lot size and drawdown limits to levels you can accept, and confirm the required margin at the deepest grid level before running live.
Trading carries risk, and you can lose some or all of your capital. Past results, including back-tests, do not predict future ones. This tool is not investment advice. Start on a demo account.
For continuous operation, a VPS with a stable connection is advisable. Check your broker's gold symbol name, trading hours and whether the account uses hedging or netting, as this affects how multiple positions are handled.

The product is listed for MetaTrader 5. Before you attach it, check that the files you receive are built for MT5 and not MT4, because an expert advisor made for one platform will not load in the other. If you are unsure, ask the store before installing on a live account.
It is aimed at gold (XAUUSD), with M15 to H1 suggested as a starting range. Other symbols can be loaded, but gold symbol names, contract sizes and spreads differ between brokers, so you should back-test and forward-test on your own broker's data first.
Open MT5, choose File then Open Data Folder, and place the expert file in MQL5/Experts. Restart the terminal or refresh the Navigator, drag the EA onto an XAUUSD chart and enable Algo Trading. Tick the option to allow algorithmic trading in the EA's properties window.
No fixed figure can be given here, because it depends on your lot size, grid depth, leverage and broker. Grid systems can hold several positions at once, so check the margin needed at the deepest grid level on a demo account before going live.
The tool is described as not relying on martingale. Even so, a grid can add positions while price moves against you, so check the lot sizing inputs and run a back-test to see how exposure grows.
Yes. Run it on a demo account with the same broker, leverage and symbol you plan to use. This lets you see how the grid behaves, confirm the settings and check execution before any real money is exposed.
