Crypto traders want clear signals, not raw charts. This AI automation combines price action across multiple timeframes with live news sentiment and delivers a plain-English Buy, Sell, or Hold recommendation straight to Telegram.
What This Automation Does
- Pulls candlestick data across 15-minute, 1-hour, and 1-day timeframes to build a multi-layered technical picture of any cryptocurrency
- Aggregates real-time global crypto news and scores the overall sentiment to validate or challenge the price-action signal
- Passes both technical and sentiment data through Gemini to produce a single, clean trading recommendation with reasoning
- Delivers the final Buy, Sell, or Hold signal directly to a Telegram chat, bot, or group channel on demand
Tools Used
- Telegram
- Google Gemini
- n8n

Wire up the crypto price data source
Configure the workflow to authenticate with a crypto exchange API so it can request candlestick data for any token across 15-minute, 1-hour, and 1-day intervals in a single pass.
Pull and structure multi-timeframe candlestick data
The workflow fetches OHLCV candles for each timeframe and normalises them into a unified data structure so all three timeframes feed the AI model as a coherent technical snapshot.
Aggregate live news sentiment for the target token
A news API call retrieves recent headlines and articles for the queried cryptocurrency, which are then scored for bullish or bearish sentiment to act as a fundamental layer alongside price action.
Run combined data through the Gemini AI agent
The structured technical data and sentiment summary are passed to a Gemini-powered AI agent with a prompt that instructs it to reason through the combined signals and output a single Buy, Sell, or Hold verdict with a plain-English rationale.
Deliver the signal to a Telegram bot or group
The final recommendation and its reasoning are formatted and pushed to a specified Telegram chat, allowing the client or their subscribers to receive the signal instantly without leaving the messaging app they already use.
Pitfalls
- Exchange API rate limits can throttle simultaneous requests for multiple tokens, causing incomplete data to reach the AI model and producing unreliable signals during high-volume runs.
- News API quotas reset on a rolling window, and if a client tracks many coins at high frequency the workflow will silently return empty sentiment data, making the AI output look bullish by default when it is actually missing half its input.
- Gemini prompt drift is real: if the system prompt is not locked and versioned, small edits to improve tone can shift the model toward more aggressive Buy signals over time, which creates liability for anyone running a subscription signal service.
FAQ
Can I build this without coding?
Yes. The workflow uses a visual low-code builder and pre-built API integrations, so the main configuration work is entering API keys and adjusting the Gemini prompt. No custom code is required to get a working signal bot live.
How long does it take?
Initial setup runs around five minutes for a single token once all API keys are in hand. Building a polished client-ready version with multiple tokens, formatted Telegram messages, and error handling typically takes two to four hours.
What can I charge?
Pricing is yours to set based on scope, but a recurring monthly retainer structured around per-token or per-subscriber access is a natural fit for this kind of managed signal bot. One-time setup fees plus ongoing hosting or maintenance charges are common packaging approaches.
Which tool is required vs optional?
Telegram and Google Gemini are core to this workflow as built. The crypto price API and news API are also required for data, though both can be swapped for alternative providers with equivalent endpoints. The Telegram delivery layer could technically be replaced with email or Slack, but that changes the real-time feel clients expect from a signal bot.
