Tradra
VisitAll-in-one market intelligence platform
Tradra is a market intelligence platform. Prices, news, charts, and comparisons in one place, so you stop juggling six tabs every time you want to check on a position.
I built it because the existing tools all do one thing well and nothing else. TradingView is a great chart. Yahoo Finance is a reasonable dashboard. Twitter is where the news actually breaks. None of them give you the full picture without switching context every few seconds.
Next.js, Tailwind, TradingView for data feeds, a financial news API, and a market data provider. Below are the decisions that mattered.
Key decisions
Use TradingView for charts
Charting is a years-of-edge-cases problem and TradingView already handles it well. I integrated their library directly instead of trying to build a charting layer. That freed me to spend time on the parts of the product that actually needed to be designed — watchlists, comparison views, and how news ties into them.
Hierarchy as the main design problem
Prices, news, indexes, and comparisons all wanted to be loud. The job became figuring out what shows up first, what stays in the background, and what only appears when you ask. I cut a lot of features that worked in isolation but added noise to the main view.
Make it feel like one product
Tradra pulls from three different data sources. The easy version of this product would have felt like three widgets sharing a page. I spent most of the design time on the small interactions between modules — clicking a stock in your watchlist updates the chart, the news feed, and the comparison panel in sync. That sync is what makes it feel like one product instead of an aggregator.
