Developer builds crypto market sensor, eschews automated trading

A developer built an hourly cryptocurrency market sentiment sensor using free data, but chose not to automate trading decisions based on its output. The system analyzes funding rates on major exchanges like Binance and Bybit, and monitors posting volume on Reddit forums such as r/Bitcoin and r/CryptoCurrency. It also scores news headlines for negative keywords and uses an LLM to assess sentiment, but the developer found that social sentiment is more of a same-day correlate than a predictor, and attention volume is a stronger signal for short-term continuation and reversal.

    I built an hourly crypto "market thermometer" from free data, then refused to let it trade

    <p>Most "AI sentiment trading" projects start by wiring a sentiment score straight into buy and sell decisions. I went through the published evidence first and ended up building the opposite: a sensor that records everything, decides nothing, and has to earn the right to influenc…
