Crypto RSI alert system with EODHD, Telegram and TradingView charts

How it works

Runs on a schedule and iterates a watchlist of symbols (e.g., BTC/ETH/SOL).

For each symbol, request intraday 1h OHLCV from EODHD.

A Code node computes Wilder’s RSI(14) and detects 30/70 crossings.

When a signal appears, the bot sends a Telegram alert (HTML message) with price, RSI (prev → now), timestamp, and a “View chart” button that opens the pair on TradingView (BINANCE/USD).

Set up steps (≈10–15 min)

Prereqs: n8n (cloud or self-hosted), EODHD API key, Telegram bot + your chatid.

Env vars: set EODHDTOKEN and TELEGRAMCHATID on your n8n instance.
