                    MERCARIA UNICORN

         Adaptive Grid Trading System

              XAUUSD · MetaTrader 5

  Built by practicing traders with years of market experience

            designed for every skill level

═══════════════════════════════════════════════════════

Mercaria Unicorn is not "just another grid" — it's an adaptive trading system for Gold (XAUUSD) and other CFD instruments. Unlike standard grid robots with fixed parameters, the advisor automatically adjusts the number of levels, lot size, and risk thresholds based on the selected volatility profile and your deposit.

All critical decisions are exposed on a visual control panel — no F7 restarts to change settings on the fly. Suitable for those who want "set and forget", for experienced traders managing risk by the news calendar, and for professionals who need an intelligent position manager on top of their own entry strategy.

═══════════════════════════════════════════════════════

   KEY FEATURES

═══════════════════════════════════════════════════════

▸ 4 VOLATILITY PROFILES

  NORMAL, SPIKE_M, SPIKE_L, BLACK SWAN. For calm days, news days (CPI/FOMC), NFP surprises, and crisis situations. Switch with one click from the panel, no restart needed.

▸ ADAPTIVE AUTOSIZING

  The advisor calculates the safe number of levels and lot size for your balance. No guesswork, only a mathematical model with built-in safety buffer.

▸ LOT SCALING

  All USD thresholds (TP, SL, trail, profit protection) automatically scale with the active lot. The same configuration works on a $300 deposit and on $30,000 — no manual recalculation.

▸ TWO-LAYER PROFIT PROTECTION

  Percentage protection (drop from peak) triggers first, then USD trail. Prevents profit from "going back to zero".

▸ PROFIT-TO-SL BONUS

  Optional mechanism: a portion of closed profit goes into the SL "cushion" of the pool. Reinvesting earnings into insurance, without risking the deposit body.

▸ VISUAL CONTROL PANEL

  6 sections (Live, Sizing, Grid, Risk, Stats, Log). Button-driven, with protection against accidental clicks (LOCK), view-only mode (READ ONLY), emergency close (PANIC).

▸ MULTI-LAYERED DEPOSIT PROTECTION

  Hard pool SL in USD, session SL-hit limit, auto-stop on session target, visual Margin Call distance indicator.

▸ FULL REAL-TIME STATISTICS

  Win rate, Avg pool PnL, Closed PnL matching balance to the cent, Streak, Max drawdown, Pools today.

═══════════════════════════════════════════════════════

   WHO IT'S FOR

═══════════════════════════════════════════════════════

▸ BEGINNER TRADERS

  Ready-made "set and forget" presets. AutoSizing CAP mode + SPIKE_M base profile + auto-stop on daily target. The advisor limits risk to your deposit. You just set the daily profit target and watch through the panel.

▸ TRADERS WITH 1–2 YEARS OF EXPERIENCE

  Semi-automatic mode. You follow the economic calendar and switch volatility profile with a click before important news. NORMAL in the morning, SPIKE_M before FOMC, SPIKE_L on NFP day. The advisor instantly recalculates safe sizing under the selected model.

▸ PROFESSIONAL TRADERS

  Mercaria Unicorn is used as a position manager. You open trades by your own strategy (price action, technical analysis, news trading), and the advisor automatically manages each position: adds levels on adverse moves, protects profit with trailing, closes by disciplined rules. No emotional decisions in heated market moments.

═══════════════════════════════════════════════════════

   PARAMETER GROUPS (F7)

═══════════════════════════════════════════════════════

All settings are logically organized into 11 groups. Most users only touch the first two.

▸ Main — Magic, LotSize, GridStepPoints, MaxGridLevels, TakeProfitUSD, MaxDrawdownUSD, MinPauseBetweenOrders. Basic grid mechanics and risk limits.

▸ AutoSizing — Mode (OFF / ADVISORY / CAP / FULL), Scenario, SafetyBuffer, MinLevels, MaxLevels, MaxLot, RescaleDown. Dynamic N×lot calculation for the deposit and scenario.

▸ Risk Scenarios — δ-overrun in points for each of 4 profiles, calibration coefficient, per-scenario lot caps. Fine-tuning the adaptive model to a specific broker.

▸ Pyramid & Recovery — UsePyramidTrail, PyramidTrailStart, PyramidTrailStep. USD trail on the floating profit peak.

▸ Profit Protection — UseProfitProtect, ProfitProtectMinUSD, ProfitProtectDropPct. Percentage profit protection on drop from peak.

▸ Profit-to-SL Bonus — UseProfitToSLBonus, ProfitToSLPercent, ProfitToSLCapUSD. Optional SL cushion from closed profit.

▸ Lot Scaling — UseLotScaling, BaseLotReference, GridTPGrowthPercent, VirtualBalanceUSD. Adapting TP/SL/trail to current lot.

▸ Candle Filter — filter by candle direction.

▸ Entries per candle — entries limit per single candle. Protection against over-trading.

▸ Session — TargetProfitUSD (daily target), MaxLossCount (session SL limit). When either is reached, the advisor stops automatically.

▸ Visual — panel font size and font.

Full parameter descriptions with examples and recommended values are in the online user guide (link below).

═══════════════════════════════════════════════════════

   MINIMUM REQUIREMENTS

═══════════════════════════════════════════════════════

  Platform:          MetaTrader 5

  Instrument:        XAUUSD (Gold) — optimal

  Account type:      Hedging (recommended) or Netting

  Chart timeframe:   any (logic doesn't depend on chart TF)

  Minimum deposit:   $300 (NORMAL, 0.01 lot) · optimal from $1,000

  Leverage:          1:100 and higher

  Connection:        VPS recommended but not mandatory

RECOMMENDED FOR BEST RESULTS:

✓ Deposit from $1,000 — gives room for all 4 profiles and FULL AutoSizing mode

✓ Account type ECN / Raw spread — low spread (1–5 pt), critical for frequent TP exits

✓ Low gold commissions (no more than $5 per lot round-turn)

✓ Broker with fast execution (no frequent re-quotes)

✓ Demo testing for at least 1–2 trading sessions before going live

═══════════════════════════════════════════════════════

   RECOMMENDED EVALUATION PLAN

═══════════════════════════════════════════════════════

To properly evaluate the advisor under your conditions:

1. Buy the product on MQL5 Market. After purchase it automatically appears in your terminal.

2. Create a demo account with a $10,000 balance at your broker. Account type — preferably Hedging (cent or standard doesn't matter for testing mechanics).

3. Test on different leverages sequentially: 1:100, 1:500, 1:1000, 1:2000, 1:3000. This gives a complete picture of how available grid levels and AutoSizing behavior change with different broker margin requirements.

4. Run at least 1–2 full trading sessions in real market conditions. Not in Strategy Tester — its results are incomplete (see below).

5. Track your metrics: Win rate, Avg pool, Max drawdown, Pools today. All visible in real time in the STATS panel section.

6. Open the detailed online user guide — it helps you interpret behavior correctly and pick parameters for your trading style.

7. Only after successful demo move to a live account. Start with the minimum lot (0.01) and gradually scale up as you build statistics.

═══════════════════════════════════════════════════════

   IMPORTANT ABOUT STRATEGY TESTER

═══════════════════════════════════════════════════════

Testing in the standard MetaTrader 5 Strategy Tester gives an incomplete picture of how the advisor works. This is because:

✗ At speeds above 75%, the tester starts to skip ticks, which is critical for grid logic sensitive to precise price movements.

✗ The tester doesn't account for real slippage and instant spread changes during news.

✗ Virtual trading inside the tester may behave differently from the broker's real execution environment.

If you want to test in Strategy Tester — required settings:

✓ Only visual mode (Visual Mode = ON)

✓ Speed no higher than 75%

✓ Modeling quality: Every tick based on real ticks

THE BEST EVALUATION METHOD — demo account testing with the real quote feed. This gives the most reliable result in real trading time.

   ⚠️  IMPORTANT RISK DISCLOSURE

═══════════════════════════════════════════════════════

Mercaria Unicorn is a trading automation tool. PAST RESULTS DO NOT GUARANTEE FUTURE RETURNS. Grid trading strategies carry a risk of significant floating drawdown during prolonged one-directional market movements. The trader bears full responsibility for choosing the risk profile, deposit size, leverage, and applying protection modes (Lock, MaxDrawdownUSD, MaxLossCount, Profit Protection). BEFORE TRADING ON A LIVE ACCOUNT, DEMO TESTING for at least 1–2 trading sessions is mandatory. Never use funds whose loss would be critical for you.
