About the Stock Trading App

Ticker is a stock trading app system design template built on a "Midnight Terminal" aesthetic: a near-black charcoal base, raised slate panels split by hairline rules, and cool slate figures set in tabular monospace so every price and ticker aligns column-perfect. Only two saturated colors appear, emerald for gains and coral-red for losses, with a muted electric-cyan reserved for the active tab and primary actions. It reads like a professional trading desk at midnight: calm, exact, and built around numbers as the hero.

The template ships six connected screens that form a complete trading flow. A scrollable Watchlist blotter pairs every ticker with a live sparkline and a tracked-out delta chip, a Stock detail screen with an interactive candlestick chart and key-stats grid, an Order ticket with Market/Limit/Stop selection and a slide-to-confirm bar, a Portfolio with a net-worth hero number, allocation donut and holdings P/L, a Discover hub of top movers and trending themes, and an Activity ledger of filled orders, dividends, and deposits with monospace timestamps.

Use it in Sleek and make it yours: restyle the palette, edit any screen with AI by describing the change, and add the flows your product needs. Then export it to code, copy it into Figma, or hand a prompt to an AI agent to build it for real, a far faster start than a blank canvas.

Screens included

Watchlist

A dense blotter of tickers with a market-index strip up top (S&P 500, NASDAQ, Dow), each row pairing a live sparkline with a price and color-coded delta chip. The at-a-glance home for tracking the market.

Stock Detail

A giant monospace price with a green delta badge over an interactive candlestick chart and 1D/1W/1M/3M/1Y/ALL range tabs, plus a key-statistics grid and a split Buy/Sell block. The core research-to-trade surface.

Order Ticket

A Market/Limit/Stop order-type selector, a quantity stepper, estimated cost and buying-power lines, and a slide-to-buy confirmation bar. Where an order gets reviewed and placed.

Portfolio

A total net-worth hero number with a day-change chip, an allocation donut split across Tech, Crypto, ETF and Cash, and a holdings list showing shares, average cost, market value and unrealized P/L. The full account snapshot.

Discover

A markets search bar above Top Movers cards with mini sparklines, trending theme tiles like Semiconductors and Web3 & Crypto, and an earnings-this-week list. The place to find new ideas.

Activity

A chronological ledger grouped by Today, Yesterday and Last Week, listing buys, sells, transfers and dividends with monospace amounts, timestamps and status labels. A trustworthy record of every transaction.

Questions, answered. Everything to know before you start.

How do I build a stock trading app from this template?

Click "Use this template" to open it in Sleek as your own editable project, then shape it by describing the changes you want: restyle the palette, edit any screen, and add the flows your product needs. You start from six complete trading screens instead of a blank canvas, so you reach a working stock trading app design far faster.

What screens are included in this stock trading app design template?

Six connected screens: Watchlist, Stock detail, Order ticket, Portfolio, Discover, and Activity. Together they cover the core flow of a real trading app, from tracking the market to placing an order and reviewing your transaction history.

Can I customize the stock trading app UI design?

Yes. Use the template in Sleek and edit any screen by chatting with the AI: restyle the Midnight Terminal palette, change layouts, swap the candlestick chart, and add or remove flows. There's no manual redraw; you describe the change and it's applied.

Does the design follow good system design for a stock trading app?

It's structured around a reusable terminal-panel system: tabular monospace numbers, hairline-separated rows, and a recurring sparkline-plus-delta chip so price movement stays legible across the watchlist, portfolio, and order screens. That consistency makes it a solid reference for both UI and the underlying screen architecture.

Is this stock trading app design template free to use?

You can open and explore the design for free, then use it in your own Sleek project to build on it. Editing and exporting follow Sleek's standard plans.

Can I export the design to code or Figma?

Yes. Sleek exports your design as code, copies straight into Figma with no plugin, or hands you a ready-made prompt that an AI agent like Claude Code or Cursor can use to build it into a real, working app.
