If you are automating TradingView on MetaTrader 4 or 5, you will choose between two architectures: TradingView webhooks (cloud relay) or a local bridge that captures alerts on your PC. Both work — the right choice depends on cost, privacy, and whether you already pay for TradingView webhooks.
How TradingView webhooks work
- You create an alert in TradingView with a webhook URL (requires a plan that includes webhooks)
- TradingView sends an HTTP POST to the bridge provider’s server
- The cloud service validates and forwards the command to your MT4/MT5 Expert Advisor
- The EA places the trade on your broker
Pros: works from any device that created the alert; mature ecosystem (PineConnector, etc.).
Cons: monthly fees, signal content transits third-party servers, extra latency hops, TV plan cost.
How a local bridge works
- TradingView runs inside the bridge app (or a browser extension reads alerts)
- Alert text is posted to
localhoston your machine - The bridge writes to a queue file in MetaTrader Common Files (shared by MT4 and MT5)
- The EA reads the queue and executes — no cloud in the middle
Pros: one-time cost possible, stronger privacy, no public webhook URL to secure.
Cons: bridge must run on Windows (or VPS); you manage uptime.
Side-by-side comparison
| Factor | Cloud webhook | Local bridge (TradingView Bridge) |
|---|---|---|
| TradingView Pro / webhooks | Typically required | Not required |
| Bridge cost | $39–159/mo typical | $99–$149 lifetime |
| Signal leaves your PC? | Yes (to cloud) | No |
| Latency hops | TV → cloud → EA | TV → local queue → EA |
| VPS needed? | Often yes for 24/5 | Same — for 24/5 |
| Security surface | Public webhook URL | Localhost only |
When webhooks are the better choice
- You already pay for TradingView Premium and want zero local software
- You need vendor-managed analytics, Telegram routing, and multi-device alert sources
- Your firm mandates a specific cloud bridge
When a local bridge is the better choice
- You refuse recurring bridge + TV webhook fees
- Alert messages contain sensitive strategy parameters
- You want predictable long-term cost on one Windows VPS
- You trade MT4/MT5 with risk controls — full on-chart panel on MT5, alert-driven on MT4
Hybrid reality check
Some “local” copiers still use a Cloudflare tunnel or similar so TradingView webhooks reach your PC. That is hybrid architecture — better than full cloud relay, but still needs webhook-capable TradingView plans. TradingView Bridge’s embedded TradingView path avoids webhooks entirely.
