Yen Move Daily for Active Retail Traders

A 3-minute audio briefing every morning that explains the latest yen intervention chatter and maps it onto the retail trader's positions, with a confidence rating on each directional call.

Target user

Retail forex traders and cross-asset investors

Features
  • Three-minute narrated recap of every yen/dollar intervention event and what triggered it
  • Position-impact estimator that maps the move to popular pairs (USD/JPY, JPY crosses, Nikkei ETFs)
  • Historical analog database showing what markets did after the last five interventions
  • Watchlist alerts when intervention language appears in central bank speeches, wire reports, or official statements
Why now

Historic interventions create rare 'first time in years' interest; retail traders want a trusted explainer without paying for a Bloomberg terminal.

Text-to-speech plus LLM plus free FX feeds is a weekend MVP
