Bloomberg Terminal is the institutional standard, but it's priced for hedge funds. Yahoo Finance is free, but the UX is stuck in 2005. Meridian closes the gap: pro tooling, modern UX, retail price.

Most consumer finance sites are point-and-click dashboards. Meridian is a keyboard-driven workspace. Same data, fewer interactions. Click any card below to open the terminal already on that task.
Multiply that across a hundred lookups a week. That's the whole pitch.
Every panel, every data point, every insight, built for traders and investors who want Bloomberg-grade tools without the $25,000 per year subscription.
Analyst-style commentary on any ticker, powered by GPT and Claude. Price action, volume conviction, 52-week positioning, and key levels to watch.
Full strike and expiry grid with bid/ask, implied volatility, volume, and open interest. Updated live. Spot unusual flow instantly.
Track positions, cost basis, and P&L across your entire watchlist. Session summaries keep you oriented at a glance.
From classic Bloomberg amber to neon Synthwave and clean Paper mode for daytime. Switch your entire workspace aesthetic in one click.
Set price targets, RSI thresholds, volume spikes, and custom conditions. Get notified in-browser or by email the moment something triggers.
Real-time headlines filtered by your watchlist. Every story scored bullish, bearish, or neutral so you can triage in seconds.
Drop a ticker in any panel, swap modules with F1 to F10, and let the AI talk you through what just happened. This is the workspace, no screenshot trickery.
Nine handcrafted color systems. From the classic Bloomberg amber on black to neon Synthwave to clean Paper mode for daytime sessions.
Meridian isn't built for a Wall Street trading desk. It's built for the people who want a Wall Street trading desk's tools but don't have a $25,000 expense account.
Live quotes, full Greek options chains, alerts on price, RSI, and volume. Built for swing setups and day-trade triage.
Paper-trade real tickers. Learn from AI commentary on live moves. The free tier covers a full investments course at zero cost.
Track client watchlists, run sector heatmaps, ship AI briefings every Friday. Pay for the data you actually use.
For newsletter writers, podcasters, and independent researchers. AI-summarized fundamentals on demand. Screenshots that look professional.
No trial periods, no credit card required. The free tier is genuinely powerful. Upgrade for live data, AI, and unlimited access.
A real terminal, not a watered-down demo.
Everything you need to trade with conviction.
For power users, teams, and builders.
Pro users get streaming live quotes. Free users get 15-minute delayed quotes, the same delay used by most consumer trackers. Both tiers refresh automatically while the panel is open.
Quotes flow through licensed market data providers. News headlines and AI summaries use public news APIs plus GPT and Claude. The whole stack is open source on GitHub if you want to inspect the wiring.
Watchlists, positions, alerts, and ticker notes stay scoped to your account. Notes are stored locally first and only sync to your workspace when you're signed in. Email is used for login and account-related notifications only, never sold or shared.
The terminal degrades gracefully: the last quotes that loaded stay on screen, charts render from cached data, and the UI surfaces a "Server waking up" indicator. The free tier sleeps when idle, so the first visit each day takes ~30 seconds to warm up.
No. Meridian is information-only. We never recommend buying or selling securities, never route orders to a brokerage, and never auto-trade on alerts. You can paper-trade in the Portfolio panel for practice.
No catch. Pro and Pro+ subscriptions pay for the live feeds and AI tokens that free users cost us. We don't sell data, run ads, or rent watchlists. The whole stack is open source (MIT) on GitHub, so you can verify the data flow yourself. Email is only used for login and account notifications.
Robinhood, Webull, and Fidelity are brokerages: you execute real trades through them, pay per transaction, and carry real money risk. Meridian is research + simulation: live quotes, AI commentary, options analysis, and paper trading. Think of Meridian as Bloomberg Terminal for your own analysis; think of Robinhood as the execution layer after you decide what to buy. Many users run both: research on Meridian, execute on Robinhood or your preferred broker.
