Pine is great for prototyping but execution is DIY. What's the most reliable alert-to-execution bridge people are using in 2026?
Webhook to a custom server? A third-party bridge service? Straight into MT5 somehow? Reliability stories welcome — I got burned by a missed alert last month.
Pine webhook to a small FastAPI server to the broker's REST API. About 200 lines, rock solid for two years.
One key detail: include a secret token and a strategy version hash in the alert JSON, so stale or spoofed alerts can't fire. After your missed-alert story I probably don't need to explain why.
For MT5 execution I run a local bridge EA that polls my server every 2 seconds. Latency is fine for anything slower than M5 scalps. Webhooks into MT5 directly are painful; polling a queue is boring and boring is good.
