MT5 Gateway API Development – Synthetic Token CFD - End-to-End Implementation

We require the design, development, deployment, and go-live of a fully functional synthetic token CFD on MetaTrader 5.

The instrument (JOJOUSD) must:

• Be visible to all clients

• Be fully tradable (long & short)

• Be priced dynamically in real time

• Display live charts and candles

• Calculate floating and closed P/L correctly in USD

• Behave exactly like a native MT5 CFD

The solution must be implemented using MT5 Gateway API (preferred) and deployed to live server infrastructure.

This is an infrastructure-level project. Code-only delivery is not acceptable.

The pricing system must:

• Be implemented using MT5 Gateway API (C++)

• Run as an external service (Windows Server environment)

• Connect directly to MT5 Server

• Stream ticks programmatically into a synthetic symbol

• Operate independently from MT5 client terminals

• Include auto-reconnect and failover logic

Terminal-based EAs are not acceptable as primary architecture.

Symbol Name: JOJOUSD

Symbol Type: CFD (Synthetic)

Base Currency: JOJO

Quote Currency: USD

Source Price: BTCUSD (live feed from existing server symbol)

Multiplier: Configurable (default 0.00002)

Spread: Fixed, configurable (default 5 points)

Digits: 5

Contract Size: 1 lot = 1 JOJO

Trading Mode: Enabled

Trading Direction: Long & Short

Margin Trading: Enabled

Trading Session: 24/7

The pricing engine must:

• Subscribe to live BTCUSD feed

• Apply configurable multiplier

• Generate bid and ask programmatically

• Maintain fixed spread (configurable)

• Update every 1–2 seconds (configurable)

• Ensure smooth and continuous tick flow

• Prevent abnormal spikes and invalid ticks

• Handle feed interruptions gracefully

• Resume automatically upon reconnection

Candle formation must be accurate and consistent.

The system must ensure:

• Clients can open and close positions normally

• Margin is calculated correctly

• Floating P/L is accurate in USD

• Closed P/L is accurate

• Long and short positions behave correctly

• No interference with other server symbols

Developer must test:

• High volatility scenarios

• Rapid BTC movement

• Spread stability

• Trade execution behavior

The solution must:

• Operate continuously 24/7

• Run without memory leaks

• Include structured logging

• Recover automatically from disconnections

• Maintain tick delay below 500ms

• Not impact MT5 server performance

Acceptance requires 72 hours of continuous stable operation.

Project is considered complete only when:

• JOJOUSD is live on production server

• Symbol is visible to all clients

• Real-time pricing is active

• Clients can trade successfully

• Charts and candles function properly

• Margin and P/L calculations are verified

• Stability test completed (minimum 72 hours)

Developer must:

• Deploy on production infrastructure

• Configure symbol parameters

• Verify trading behavior

• Provide full installation documentation

• Provide maintenance guide

Architecture must allow future synthetic tokens to be added without major redesign.

The system should support multiple derived instruments if required.

• Proven MT5 Gateway API development

• Experience building liquidity bridges or pricing engines

• Strong understanding of MT5 symbol configuration

• Understanding of margin, contract size, and P/L logic

• Experience deploying infrastructure on Windows Server

• Familiarity with broker-level MT5 environments

Applicants without Gateway API experience will not be considered.

1. Gateway-based pricing engine (source code included)

2. JOJOUSD live and tradable

3. Stable real-time pricing integration

4. Deployment documentation

5. Configuration manual

6. Logging and monitoring capability

The project is complete only when JOJOUSD behaves identically to a native MT5 CFD and operates continuously in live market conditions without instability.
