What is QuantLink: The Signal Relay for Quantitative Trading Strategies

The Gap Between Strategy and Execution

If you build quantitative trading strategies on JoinQuant, you already know the story. The backtest looks flawless. The Sharpe ratio is beautiful. The drawdown is manageable. Then comes the hardest part: getting those signals to execute automatically on your QMT or PTrade terminal.

Most quant traders end up in one of these situations:

• Manual relay — watching the JoinQuant console and manually entering orders into QMT. Reliable, but slow, exhausting, and defeats the purpose of automation.
• Self-built middleware — writing a custom script to bridge the two systems. It works, until it doesn't. Server outages, duplicate signals, missing acknowledgments, and no monitoring.
• Doing nothing — keeping the strategy on JoinQuant's simulated environment and never executing it live.

None of these options scale. That is the problem QuantLink solves.

What QuantLink Does (and Doesn't Do)

QuantLink is a signal relay platform. Think of it as a postman for trading signals.

What it does:

• Receives trading signals from your JoinQuant strategy via webhook
• Relays those signals to your QMT or PTrade terminal in real time
• Tracks delivery status, execution latency, and position data
• Monitors for drift between virtual and actual positions

What it doesn't do:

• It never touches your funds or trading accounts
• It never modifies your trading logic or strategy parameters
• It never executes trades on your behalf

Your terminal remains in full control of order execution. QuantLink simply ensures the signal gets there — fast, reliably, and without duplicates.

How the Signal Relay Works

The core flow is straightforward:

JoinQuant Strategy
  │  (Python code with injected signal calls)
  ▼
QuantLink Webhook Receiver
  │  (authenticates, deduplicates, normalizes)
  ▼
Signal Delivery Queue
  │  (per-terminal, cursor-based polling)
  ▼
QMT / PTrade Terminal
  │  (pulls signals, executes locally)
  ▼
Execution Confirmation
  │  (acknowledgment + latency tracking)
  ▼
Position Drift Monitoring

Every step is authenticated, logged, and auditable. Signal deduplication uses SHA-256 payload hashing to guarantee that no signal is ever processed twice — even under network retries or terminal reconnections.

Comparison with Alternatives

With QuantLink, you get the automation of a custom-built solution without the operational overhead. There are no servers to maintain, no scripts to debug at 3 AM, and no risk of duplicate signal execution.

Who Is QuantLink For?

QuantLink is built for two audiences:

• Individual quant traders who run their own JoinQuant strategies and want a reliable, hands-off way to execute on QMT or PTrade.
• Trading teams that need to share strategies across multiple terminals, manage permissions, and monitor execution quality at scale.

If you have a JoinQuant strategy that generates trading signals and a QMT or PTrade terminal ready to receive them, QuantLink connects the two in minutes — not days.

Key Advantages

• Full automation — from signal generation to terminal execution, no human intervention required
• No fund custody — your terminal, your broker, your money. QuantLink only relays.
• Local execution — all trades execute on your machine, behind your firewall
• Signal deduplication — SHA-256 payload hashing prevents duplicate orders
• Position drift monitoring — daily comparison of virtual vs. actual positions
• Strategy sharing — share strategies with teammates, with granular permissions and expiration controls

QuantLink is the missing link between strategy research and live execution. If you are tired of the gap between your backtests and your real portfolio, this is the bridge.
