HighLowTicker - A fast lightweight market scanner
Hey IH,
I'm Jerald. For the last ~18 months I've been deep in the weeds building HighLowTicker, a terminal app that surfaces every single symbol printing a new intraday high or low in real time, with running counts, rate bars (20m/5m/1m/30s), regime detection, z-scores, momentum, and a clean scrolling tape.
Why I built it
Most platforms give you price alerts or heatmaps, but nothing shows you the actual flow of new highs and lows across hundreds/thousands of symbols in one glance. Day traders, swing traders, and market-makers live and die by order flow and rotation. I wanted something fast, keyboard-driven, and always-on that doesn't cost $50–200/month like the big platforms.
Current product (v1.0.1)
Rust + Ratatui TUI (blazing fast, ~8–9 MB binary)
Supports Schwab, Tastytrade, Tradier, IBKR, Alpaca, Polygon, etc. + Coinbase for crypto
Trial = Yahoo + Coinbase (3 days, no card)
Pro = $199 one-time → unlocks everything + custom ticker lists (up to 6k symbols)
Two-machine license, 48h offline grace, perpetual key
Auto-setup wizard, clean installers (DMG + Windows EXE)
No subscriptions. Ever. "Pay once. Own it forever." is the motto.
Live site: https://highlowtick.com
The journey (quick timeline)
Started with Python + Schwab
Rewrote in Rust for performance and distribution sanity
Built my own licensing + Stripe/Whop + Netlify backend
Shipped proper macOS .app bundle + Windows installer
Went through the painful but necessary provider drama (Schwab OAuth, Tastytrade reconnects, Tradier handshakes, Windows install issues etc.)
Revenue so far
Very early days, first real marketing push starts this week. A handful of sales from small trader communities. Goal is to reach $5k–10k in one-time revenue quickly and turn this into a sustainable solo business.
What I'm hoping to learn from you
How do you market a one-time purchase developer tool in 2026? (Especially to traders who are notoriously skeptical)
Any brutal feedback on the landing page or positioning?
Would you pay $199 for this if you day/swing trade?
Happy to answer any questions and share the tech decisions, packaging scripts, licensing flow, etc.
Thanks for reading, and I am rooting for all of you building in public.
