Building a Human-in-the-Loop News Overlay for Trading Charts
Summary
The document describes FUSE, a monitoring tool that places timestamped financial headlines on a candlestick chart. It fetches flash updates and longer articles through a standardized interface, normalizes their different fields, removes duplicates, and filters headlines by user-selected keywords. Selected items become markers aligned to the corresponding price bar, while a status panel combines quotes, account equity, positions, and news. A manual command interface also supports basic order actions and position-size changes.
The article illustrates the design with code and a crude-oil news episode, but it reports no performance test showing that the overlay improves trading results. The markers establish a time relationship between a headline and a bar; they do not determine whether news caused a move or whether it is bullish or bearish. Keyword matching can miss relevant stories or surface unimportant ones, and human interpretation and reaction speed remain limiting factors. The system is presented as an information aid, not an automated trading signal.
Key ideas
- Timestamped headlines can be normalized and displayed as markers on their corresponding candlestick bars.
- Keyword filters reduce the number of headlines shown, but they do not measure news importance or market direction.
- A combined panel can display prices, positions, account status, and selected news for manual monitoring.
- The chart overlay shows timing rather than causality, leaving interpretation and trading decisions to the user.
