Finance Newsletter Writers

Ship interactive financial charts in every issue — yield curves, vol surfaces, and FedWatch probabilities that Substack's native charts can't do.

Finance newsletters are booming. But the chart options are limited: Substack's built-in TradingView (basic stock charts only) or Datawrapper (no finance-specific types). Quadesto fills the gap with 30+ finance-aware chart types that embed in any newsletter platform.

The workflow

Connect your data source (Alpha Vantage, FRED, or custom API). AI builds the optimal chart. Copy the embed URL. Paste in Substack, Beehiiv, or Ghost. Your readers get an interactive chart; you spent 30 seconds.

What sets this apart

Volatility surfaces, yield curve interpolation, FedWatch probability trees, options chain tables. These are the charts that make finance newsletters look professional and data-driven. No other embed tool offers them.
