Fast signal processing
Measure the bridge path separately from broker execution, spreads, terminal state, and market liquidity.
Technical playbook
Low-Latency Trade Copier Architecture in Simple Terms.
Synnectra's execution path is designed around a narrow signal flow: TradingView webhook, Go backend validation, risk and symbol rules, ZeroMQ transport, MetaTrader EA execution, then dashboard evidence.
Architecture path
Keep the signal path short and observable.
Low latency does not help if the system is impossible to audit. Synnectra keeps execution speed and dashboard visibility together.
TradingView webhook -> Go signal parser -> Authentication and risk layer -> Symbol mapping and lot sizing -> ZeroMQ command channel -> MT4/MT5 Expert Advisor -> Execution result and dashboard history
- Webhooks make TradingView the signal source without requiring manual terminal work.
- Go keeps signal validation and routing predictable under load.
- Risk checks run before the terminal receives a command.
- ZeroMQ handles the command path to connected MetaTrader terminals.
- The dashboard records fills, errors, and account state for later review.
Design principles
What technical traders should look for in a copier.
Deterministic parsing
Structured alert messages reduce ambiguity and make failed alerts easier to diagnose.
Pre-execution risk layer
Daily loss, news, cooldown, and max-trade rules should run before the order reaches MetaTrader.
Symbol normalization
Broker-specific symbols should be mapped before commands are sent to MT4 or MT5.
Account routing
Multi-account trade copying needs explicit groups and per-account overrides.
Observability
Execution history, account status, errors, and notifications should be available without digging through terminals.
| Layer | Responsibility | Why it matters |
|---|---|---|
| TradingView | Creates the strategy alert and webhook payload. | The signal should be explicit, parseable, and authenticated. |
| Go backend | Receives, validates, maps, sizes, and routes the signal. | This is where risk logic can stop a bad command before execution. |
| ZeroMQ channel | Moves the final command to the connected MetaTrader side. | The bridge needs a fast, narrow path from server logic to terminal instruction. |
| MT4/MT5 EA | Executes through the user's MetaTrader terminal and broker connection. | Broker execution is separate from signal processing latency and must be monitored. |
| Dashboard | Shows account health, trade history, performance, risk, and errors. | Traders need proof of what the automation did, not just an alert that fired. |
Use a low-latency bridge you can still inspect.
Synnectra combines the TradingView to MetaTrader path with account controls and execution evidence.
