We Built a Real-Time Trading Data Browser That Actually Works

Live market data streaming at 60 frames per second, handling over a million rows without breaking a sweat. Here's what it looks like and why it matters for traders.

Most trading platforms give you one of two bad options:

  1. Real-time data that chokes when you try to look at more than a few thousand rows
  2. Historical data that loads fast but isn’t actually real-time

We built something different.


The Problem: You Can’t See What’s Happening

If you trade seriously, you need to see every tick. Not summaries. Not samples. Every single price update, as it happens.

But most platforms can’t handle it:

  • Load more than 50,000 rows → browser freezes
  • Try to scroll → UI stutters and lags
  • Filter or search → entire page reloads
  • Switch between symbols → start over from scratch

Result: You’re flying blind, making decisions on incomplete data.


What We Built: Real-Time Data That Scales

Matchstick Stream - Data Grid 1 million rows, 60fps scrolling, instant search

Here’s what you’re looking at:

  • 1,000,000+ rows of tick data loaded
  • 60 frames per second smooth scrolling
  • Instant search across the entire dataset
  • Sub-second filtering by symbol, exchange, or price range

No freezing. No stuttering. No waiting.


How It Actually Looks

Browse Raw Tick Data

Data Explorer View Every tick, every update, in real-time

See timestamp, symbol, price, size, exchange. Scroll through millions of rows like you’re browsing a spreadsheet.

Watch Live Market Data Stream In

Live Connection Status Connected to live data feed

Real-time WebSocket connection to our trading engine. Ticks flow in continuously, updating the grid in real-time.

Switch to Charts Instantly

Charting View Same data, different view - no reload needed

One click switches from raw ticks to candlestick charts. Same underlying data, just visualized differently.

Aggregate On Demand

1-Minute Bar Aggregation Convert ticks to bars without reloading

Don’t need tick-level data? Aggregate into 1-second, 1-minute, or 1-hour bars instantly. The browser does the math - no server roundtrip.


Why This Matters

For Day Traders

You need to see order flow in real-time. Not delayed quotes. Not sampled data.

With Matchstick, you see every tick as it comes in. Spot opportunities before they disappear.

For Quant Researchers

Backtesting requires massive historical datasets. Most tools choke when you load more than a few days of tick data.

Matchstick handles years of tick data. Scroll through millions of rows, filter instantly, export what you need.

For System Developers

Building trading infrastructure means testing with real-world data volumes.

Matchstick gives you a local-first data browser that runs on your laptop. No cloud dependencies. No API rate limits.


The Technical Reality (Without the Jargon)

Virtual Scrolling

We don’t render all million rows at once. We render what you see (about 30 rows) and intelligently load the rest as you scroll.

Result: Instant startup, smooth scrolling, minimal memory usage.

Smart Caching

Data you’ve already seen stays in memory. Scroll back and forth? Instant.

Result: Once loaded, navigation feels instantaneous.

Real-Time Streaming

Our Rust trading engine generates ticks and streams them over WebSocket. The browser receives chunks and updates the grid without blocking.

Result: New data appears in real-time without freezing the UI.

Performance Stats

Here’s what the system can handle:

MetricPerformance
Rows Loaded1,000,000+
Scroll FPS60fps constant
Search Time<100ms across entire dataset
Memory Usage~150MB for 1M rows
Startup Time<2 seconds

For context, most web-based trading platforms start stuttering around 10,000 rows.


How We Use It Internally

Strategy Development

Load historical data, replay it at high speed, watch our strategies react. Catch bugs before they cost money.

Performance Monitoring

Connect to live feeds, monitor latency, verify we’re seeing every tick. Quality assurance in real-time.

Client Demonstrations

Show prospects what real-time infrastructure looks like. No slides, no promises - just working software.


Settings & Configuration

Settings Panel Switch between mock data and live feeds

Mock Mode: Test with generated data (perfect for demos) Live Mode: Connect to real market data feeds

No complex setup. Just click and connect.


What’s Next

The Bottom Line

Most trading platforms promise real-time data but can’t deliver when you push them.

We built a data browser that actually handles real-time streams at scale.

  • 1M+ rows? No problem.
  • 60fps scrolling? Standard.
  • Instant search? Built-in.
  • Real-time updates? Continuous.

This isn’t marketing. This is working software you can use today.
