InfluxDB is used to store and analyze Bitcoin price data from the CoinMarketCap API, allowing users to calculate a simple Momentum signal. The signal is generated by crossing the 1-day moving average over the 5-day moving average, resulting in a buy or sell signal when the 1-day MA crosses above or below the 5-day MA. A Telegraf agent is used to collect data from the API and store it in InfluxDB, while Flux is used to calculate the Momentum signal and set up alerts for specific conditions. The system includes an alerting feature that sends notifications to a Slack channel when the momentum signal reaches a certain threshold, allowing users to stay informed about market trends and make trading decisions based on automated analysis.
