Tapeboard is a professional-grade market terminal that runs entirely in your browser — no install, free to start. It consolidates 14 modules into one tab: a real-time stock scanner (gap-ups, unusual volume, premarket movers, plus custom screens you build in plain English), advanced charting with 44 indicators (RSI, MACD, Bollinger Bands, volume profile), SEC EDGAR filing search (10-K/10-Q/8-K), Form 4 insider-transaction tracking, a daily short-squeeze leaderboard scored on FINRA short interest + IBKR borrow fees + float utilization + days-to-cover + momentum, options flow and gamma exposure, 800K+ economic data series, crypto, a free trade journal with analytics, and a realistic paper-trading simulator. Built for retail traders who want a Bloomberg-terminal experience without the Bloomberg price.
Options Backtesting Engine TapeboardTapeboard's answer:
Tapeboard combines a real-time stock scanner, full charting suite, SEC filings analysis, short-squeeze detection, and paper trading into one workspace — built for the speed at which day traders actually operate. Most competing tools force you to tab between a screener, a chart, and a filings reader. Tapeboard surfaces all of those on one screen: you see what's moving, why it's moving (dilution, shelf registrations, short interest, news), and can execute in a paper-trading simulator without leaving the page.
Tapeboard's answer:
Tapeboard's scanner runs 9–12 presets simultaneously in a grid view (pre-market gap-ups, top gainers, unusual volume, short-squeeze setups, penny runners, power-hour surges). The short-squeeze leaderboard — backed by live SEC short-interest data, days-to-cover, and fee rates — is something that normally requires a paid Bloomberg or Ortex terminal. Tapeboard offers it free, alongside integrated level-2 montage, time & sales, depth charts, and AI research that can break down any stock in plain English. The natural-language custom scanner lets you describe what you want in plain English ("US stocks below $5, rvol 200%, float below 15M") and it builds the scan for you.
Tapeboard's answer:
Active retail day traders and swing traders who need real-time market scanning, short-squeeze setups, and fast access to SEC filings — but don't want to pay $100–$300/month for a Bloomberg, Trade The Screen, or Benzinga Pro terminal. The product is built for people who trade penny stocks, low-float runners, and high-momentum names where seconds matter.
Tapeboard's answer:
Tapeboard was built by a former Webull power user who was frustrated that no single platform combined real-time scanning, charting, SEC filings, and short-squeeze intelligence without gating each feature behind an expensive upsell. The goal was to build the tool he wished existed: one screen where you can see what's moving, dig into why (dilution risk, short interest, shelf registrations), paper-trade it, and catch the next short squeeze — all without paying Bloomberg prices.
Tapeboard's answer:
Tapeboard currently serves individual retail day traders and small trading groups. The platform is in an early growth stage with a growing base of active free-tier users and a small but engaged group of Pro subscribers ($39/month). The product is particularly popular among traders who discovered it via StockTwits, Google search, and AI engines like ChatGPT and Perplexity recommending it as a free stock scanner.
