Traderline is a professional desktop Trading Interface for Polymarket (and Betfair) built by Mythical Technologies Lda in Coimbra, Portugal. Founded in 2011 by four engineers and traders inside the Instituto Pedro Nunes incubator, the team rebuilt the codebase from scratch in 2025 and launched the Polymarket version on 21 May 2026. It targets professional traders who need a vertical ladder UI, one-click scalping, automatic stop-loss, charts, and bankroll-management tooling — order types and execution speed that the official Polymarket web app does not natively offer. The software is completely free on both Polymarket and Betfair with no subscription and no premium charge on winners. Traderline reports 150,000+ registered traders across 20+ countries; on the Polymarket Builders leaderboard it sits at rank #20 for the 1-month window with $4.35M routed across 118 active users, signalling healthy pro-trader adoption rather than whale concentration. Support runs through WhatsApp and the @traderline_app Telegram channel.
Traderline is a desktop trading application built for professional Polymarket traders, with the same product line also covering Betfair exchange — i.e. the team has prior pro-trader chops from the matched-betting / Betfair ecosystem. Once connected, the ladder, charts, and one-click execution UI are immediately ready. Both apps (Polymarket + Betfair) are free with no subscription. Rank #20 on the 1-month Polymarket Builders leaderboard with $4.35M routed and 118 active users — at this scale the user count signals healthy retail-pro adoption rather than whale concentration.
The company behind it is Mythical Technologies Lda (VAT 513557849), based at the Instituto Pedro Nunes technology incubator in Coimbra, Portugal, adjacent to the University of Coimbra. According to their about page, the four founders started Traderline in 2011 because the Betfair trading software then on the market was "too slow, too complicated, or locked to Windows." In 2025 they replaced the entire codebase from scratch and that same year expanded into Polymarket, going live on 21 May 2026. The team is currently six people; founders' individual names are not disclosed publicly on the website.
Product surface: vertical ladder with a NET button (scalping-focused), fast entry/exit execution, automatic stop loss, bankroll management, charts. Windows, Mac and iOS are supported on Betfair; the Polymarket build is desktop-first. Pricing is completely free, with no maker/winner premium on Polymarket. Support is via WhatsApp and the Telegram channel @traderline_app.
Note: original known_overrides.json had traderline.app; correct canonical site is traderline.com per Polymark.et + the team's own download page.
