Advanced Algorithmic Core

4 Volatility Profiles

Quick switch between NORMAL, SPIKE_M, SPIKE_L, and BLACK SWAN settings depending on the economic calendar (FOMC, CPI, NFP).

Lot Scaling Engine

TP, SL, trailing, and profit protection thresholds automatically scale whenever the lot size changes manually or via AutoSizing.

Two-Layer Profit Protection

Percentage-based protection locks in profit upon pullbacks from peaks, followed by standard trailing to ensure maximum returns.

Profit-to-SL Bonus

Optional reinvestment mode: a portion of closed profits is added to the session allowed drawdown cushion to withstand larger moves.

Volatility & Sizing Simulator

Model the on-chart MT5 sizing panel. Set your balance, leverage and volatility profile — the engine sizes the grid and tells you whether the balance, leverage and volatility actually fit together.

The Sizing Engine picks a safe starting lot for your balance and profile, and recommends the leverage.

Frequently Asked Questions

What is the absolute minimum capital required to run Unicorn GOLD EA?

The minimum capital is $300 on a Cent account (where it translates to $30,000 cents for micro-lots). On standard accounts, we recommend a minimum deposit of $1,000 to safely utilize the Spike_M and Spike_L volatility profiles.

Does the EA require constant manual monitoring?

No, Unicorn GOLD EA can be run on 100% automated mode. However, semi-automatic management yields the best risk-reward: checking the economic calendar daily and selecting a higher volatility profile (like Spike_M) before major news releases.

Why is Gold (XAUUSD) recommended for this strategy?

Gold features deep liquidity and high daily volatility, which is perfect for scalping and short grid recovery cycles. While optimized for Gold, the EA can trade other CFD instruments by calibrating the Grid Step in settings.

Can I test the EA before purchasing?

Yes, a free demo is available on the MQL5 Market page. We strongly recommend testing the advisor on a demo account for at least 1–2 full trading sessions to verify your broker execution, spreads, and margin calls.
