Description
📉 Buy the Dip Alert (Telegram/Slack/SMS)
📌 Overview
This workflow automatically notifies you when Bitcoin or Ethereum drops more than a set percentage in the last 24 hours. It’s ideal for traders who want to stay ready for buy-the-dip opportunities without constantly refreshing charts.
⚙️ How it works
- Schedule Trigger — runs every 30 minutes (adjustable).
- HTTP Request (CoinGecko) — fetches BTC & ETH prices and 24h % change.
- Code Node (“Dip Check”) — compares changes against your dip threshold.
- IF Node — continues only if dip condition is true.
- Notification Node — sends alert via Telegram, Slack, or SMS (Twilio).
Example Output:
Dip Alert — BTC –3.2%, ETH –2.8%
Not financial advice.
🛠 Setup Guide
1) Dip threshold
- Open the Code node.
- Change the line:
const DIP = -2.5; // trigger if 24h drop <= -2.5%
Set your preferred dip value (e.g., –5 for a 5% drop). 2) Choose your alert channel Telegram: add your bot token & chat ID. Slack: connect Slack API & set channel name. Twilio: configure SID, token, from/to numbers. 3) Test Temporarily set DIP to 0 to force an alert. Run once from the Code node → confirm alert message text. Execute the Notification node → confirm delivery to your channel. 🎛 Customization Cadence: change Schedule Trigger (every 5m, 15m, hourly, etc.). Coins: extend the CoinGecko call (add solana, bnb) and update Code node logic. Multiple alerts: duplicate IF → Notification branch for different thresholds (minor vs major dip). Combine with “Threshold Alerts” workflow to cover both upside breakouts and downside dips. Storage: log alerts into Google Sheets for tracking dip history. 🧩 Troubleshooting No alerts firing: check CoinGecko API response in Execution Data. Wrong %: CoinGecko returns usd_24h_change directly — no math needed. Duplicate alerts: add a debounce using a Sheet/DB to store last fired time. Telegram not posting: confirm bot has access to your channel/group.
