+1,591.78% Historical Net Profit — With Risk Set to 0.50%
From January 2023 through September 2026, the continuous XAUUSD backtest recorded USD 1,591,777.79 in net profit from an initial deposit and Fixed Base of USD 100,000, with 15.68% Equity Drawdown Relative.
These results used the EA’s default 0.50% risk setting per base order. Explore the annual results, monthly performance and drawdown figures below to see the full picture.
****Robustness Testing
Passed out-of-sample testing (blind test - forward test) on 2021–2022 data and stress testing under elevated spread conditions. Robustness was further assessed through Monte Carlo simulations to evaluate sensitivity to changes in trade sequences and estimate potential drawdown variability****

Why Happy Nebula Gold?
15 trading engines — Each follows its own predefined entry and cycle rules.
Built-in SL/TP — Protective and target levels are defined by the strategy.
Risk of Base — Position sizing uses the selected capital base and risk percentage.
Two capital modes — Fixed Base or Auto Balance; the capital and risk settings used for each cycle remain fixed throughout that cycle.
Focused dashboard — Connection status, daily performance, trade counters and engine states, with expanded and compact views.
UTC+7 timing — Engine schedules follow Vietnam time, with broker-time alignment.
---------------------
Simple Setup
Symbol: XAUUSD / broker-compatible GOLD symbol
Platform: MetaTrader 5
Account type: Hedging
Capital mode: Fixed Base (default) or Auto Balance
Default Base Capital: 1,000 account-currency units
Default Risk: 0.50%
Allowed Risk Range: 0.20%–2.00%
Broker UTC (Backtest): 0 by default; adjust to match the historical broker server offset.
Fixed Base uses the amount you enter. Auto Balance uses the account balance when a new engine cycle is initialized, allowing sizing to change with the balance between cycles. It does not continuously resize an existing cycle.
Use a low-spread trading environment; a Raw Spread account is recommended. Keep MT5 running and Algo Trading enabled. Select a capital base appropriate for your broker's contract size, minimum lot and margin requirements. The default base is a sizing reference, not a guarantee that USD 1,000 is sufficient for every broker.
---------------------
Historical Testing
The historical reports cover January 2023–September 2026, using XAUUSD, Fixed Base USD 100,000 and Risk 0.50%.
The continuous test recorded USD 1,591,777.79 net profit (+1,591.78% of the initial deposit), a Profit Factor of 1.20 and Equity Drawdown Relative of 15.68%.
Screenshots include the full-period balance curve, independent annual tests and monthly results. The monthly table uses the continuous report and shows Balance DD, which excludes floating losses and differs from Equity DD. Independent annual tests can differ from calendar-year totals in the continuous test.
---------------------
Important Risk Notice
The risk setting applies to a base order, not to the entire account or the total loss of a trading cycle. Multiple engines and subsequent cycle orders can create simultaneous exposure.
When the calculated volume is below the broker's minimum, the EA uses the minimum permitted lot. Actual risk may therefore exceed the selected percentage. Stop Loss execution can also be affected by slippage or gaps. Trading can result in substantial losses.
---------------------
Demo Testing
The Market demo runs in the MT5 Strategy Tester. Start with XAUUSD H1 and test at least one full month. H1 is the tester chart setting; the engines use their internal timeframes.
If the test or EA starts after an engine's scheduled preparation, that engine may skip the first eligible session. Let the test continue through subsequent trading days.
Happy Nebula Gold — More engines. The same commitment to discipline.
