Bitcoin, Ethereum or gold: choose an MT5 EA by how it trades
A trading robot is easier to evaluate when you can explain how it opens, sizes and closes a position. My four MT5 Expert Advisors use different approaches. This guide helps you choose what to investigate before you spend money.
I am Fabien Martino. I started programming at 14, which gives me 30 years of software development experience, alongside 7 years in trading. My MQL5 Market portfolio has been published since June 2026. Experience is useful; transparent, reproducible evidence still matters for every individual strategy.
Watch: choose by trading method
Four approaches, four different exposure profiles
| EA / current version | Market and decision | What to examine first |
|---|---|---|
| QuantumBit Pro 1.20 | Bitcoin H1 adaptive grid, filtered by the H4 trend. ATR spacing and basket exits. | Accumulated grid exposure, level and lot limits, trend changes and losing baskets. |
| Gold Regime H1 Pro 4.10 | Gold H1 regime following, volatility-based position sizing and ATR management. | Trend reversals, equity drawdown and whether the profit trail suits the market period. |
| Crypto Portfolio Trend 1.40 | BTC and ETH breakouts from one H1 instance, with shared risk budgets. | Correlation, combined open risk, pyramid adds and broker symbol mapping. |
| Bitcoin Regime H1 Pro 2.00 | Bitcoin H1 regime following and volatility-based exposure rebalancing. | Exposure caps and the difference between the reference profile and the no-adverse-move-add profile. |
Two clarifications about the current portfolio
QuantumBit uses a grid. My June profile introduction stated “no grid” across all products; that general statement does not describe this portfolio. Features, execution timing and protections differ by EA and must be checked on each product page.
The Gold product is still listed as Gold Range Grid Mean Reversion. Its current 4.10 strategy is Gold Regime H1 Pro, a trend/regime system with additional entries disabled by default. Use the current version and matching SET rather than inferring the strategy from the historical listing name.
Choose the test before the product
- Write down the exact broker symbols and contract specifications. BTCUSD, ETHUSD and gold contracts differ between brokers.
- Choose several test windows, including a difficult or losing period. Record the version, inputs, deposit, leverage and tick model.
- Read maximum relative equity drawdown alongside return. A profitable final balance can conceal substantial floating losses.
- Inspect entries, adds and exits in the visual tester. Compare them with the documented strategy rules.
A trend strategy can struggle in sideways conditions. A grid can accumulate positions through adverse moves. Two crypto symbols do not necessarily diversify risk. Volatility-based sizing adapts exposure but does not eliminate loss. Controls are software actions, not guaranteed loss ceilings.
Start with the free resources
The EA Setup Hub contains the strategy comparison, version-specific SET files, native MT5 reports and installation instructions. Use the free Market demo in the MT5 Strategy Tester before buying. It cannot run on a demo-account chart. After purchase or rental, evaluate on a demo account before considering live use.
For setup help, use MQL5 private messages or product Comments with the version, symbol and relevant journal lines, removing account identifiers and credentials. Backtests are historical simulations, not a live track record. Leveraged trading can cause substantial losses, and past performance does not guarantee future results.
