OpenMarket review: charts, order flow, wrun

By Editorial Team
Last updated: October 2026
Disclosure: This page contains no affiliate links and no payment was received from OpenMarket for this review.

TL;DR: OpenMarket is a browser‑based charting platform with order‑flow overlays and wrun (TypeScript‑style) scripting. Free tier has tight caps; Plus is $29 per month billed annually ($35 monthly). Strategies simulate only; alerts run in the vendor’s cloud. Perps execution via Hyperliquid isn’t available to US or Malaysia residents.

Key facts
– Runs in the browser; free to start (per the vendor homepage); no native iOS or Android app, mobile browser only
– Plus costs $35 per month, or $29 per month billed annually ($348 a year); CME real-time data (from $7 per month) and API access are priced separately (per the Plus plan page)
– Order‑book heatmaps, footprints, CVD, and liquidation maps are offered across covered markets (vendor claim)
– wrun scripting: TypeScript/AssemblyScript syntax, compiled to WebAssembly; strategies never place real orders (docs: wrun introduction; strategies overview)
– Alerts to Telegram/Discord/email/webhook; run in the vendor’s cloud and require published indicators (docs: alerts function)
– Execution: Hyperliquid perps via wallet; US stocks/ETFs via Alpaca; OpenMarket says it does not route or hold orders (see the Terms)
– Wallet Execution is unavailable to Restricted Persons (includes residents of the United States and Malaysia) (Terms)

This review is documentation‑based (vendor website, docs, Terms); no hands‑on testing was performed.

Verdict: OpenMarket makes sense if you want browser‑first charts with order‑flow overlays and you can live with simulated strategies and cloud‑run alerts. Skip it if you need automated live trading from scripts, perps execution as a US/Malaysia resident, or a native mobile app (there is none; the platform works in a mobile browser).

Risk warning: Trading in stocks, futures, perpetual contracts and digital assets involves substantial risk of loss and is not suitable for every person. Past performance does not predict future results. Leveraged products can lose more than expected.

Who OpenMarket is for, and who should skip it

OpenMarket suits order‑flow traders who value heatmaps, footprints, CVD and liquidation maps alongside classic indicators (vendor claim). Coders who prefer TypeScript‑style syntax can write wrun indicators that compile to WebAssembly (docs). Multi‑venue crypto users and US equity traders with a supported Alpaca Securities LLC account can chart and optionally place orders from the browser (Terms).

Skip OpenMarket if you need real‑order automation from strategies; wrun strategies are simulated only and do not place live orders (docs). US and Malaysia residents who want in‑chart perps execution cannot use the Hyperliquid wallet integration (Restricted Persons) (Terms). If you require a native iOS or Android app, note that there is none: the platform works in a mobile browser, and the vendor recommends desktop or tablet for complex analysis (vendor FAQ).

Pricing & plans

OpenMarket has a Free plan and a Plus plan. Plus costs $35 per month billed monthly, or $29 per month billed annually ($348 a year; the billing toggle advertises about 20% savings), in US dollars, per the vendor’s Plus plan page. The page opens for anyone, and the same USD prices came back for sessions from 10 countries; pricing at checkout was not tested. Cancelling is allowed at any time: upgrades are instant, downgrades take effect at the end of the billing cycle, and there are no cancellation fees. Plus can also be unlocked without paying, with an OpenMarket+ code or by trading on Hyperliquid through OpenMarket (the vendor lists $100k traded in 30 days for 31 days of Plus, no card).

Some costs sit outside the plans. CME real-time data (CME, CBOT, NYMEX, COMEX) is a separate add-on licensed apart from the plan, from $7 per month; the vendor’s price list shows $7 (L1), $45 (Depth) and $538 (Depth Pro) per month. API access is also priced separately: the Data API tiers are Lite $99, Basic $199 and Advanced $599 per month ($990, $1,990 and $5,990 per year). The plans cover the charting platform only.

Free vs Plus matters for workflow. On Free, you can run 3 data indicators plus unlimited classic indicators (the wrun docs word the cap as 3 across your charts), set 2 indicator alerts and 100 price alerts, and keep up to 100 saved scripts, 10 workspaces and 1 session (device), with 3 widgets per layout. Plus raises those limits to 10 indicators per chart, 25 indicator alerts, 500 price alerts, 500 saved scripts, 50 workspaces, 5 sessions and 10 widgets per layout. Plus also adds 1-second candles and Maximum heatmap depth (Normal on Free); heatmap resolution is 4K on both plans. If you rely on multiple order‑flow overlays or many alert conditions, those caps will force consolidation or an upgrade; if you primarily code and iterate, the saved‑script limit is a gating factor. The vendor lists sixteen charts in one view, but its public plan page and a logged-in Free account show different Free figures, so this review does not state a Free multichart limit.

Features that matter

OpenMarket charts and order‑flow tools

The homepage states OpenMarket offers order‑book heatmaps, footprint charts, cumulative volume delta (CVD) and liquidation maps on the covered markets, plus 80+ built‑in indicators and up to sixteen charts in one view (vendor claims). These tools address common gaps in mainstream charting for perps/futures traders when DOM‑style context and liquidations data are needed alongside price. If you regularly watch several instruments or timeframes, the sixteen‑panel layout is a practical ceiling (vendor claim). Treat the “80+ indicators” figure as a marketing total rather than a catalog.

wrun scripting and the Strategy Tester

wrun is OpenMarket’s scripting engine for custom studies. It uses TypeScript/AssemblyScript‑style syntax with numeric types (for example, f64 and i32) and compiles to WebAssembly in the browser (docs: wrun introduction). The language distinguishes indicators from strategies. Strategies run in a Strategy Tester that outputs a trade list, equity curve and stats, but strategies do not place real orders; wrun never executes live trades (docs: strategies overview).

Per the vendor’s wrun‑vs‑Pine comparison, a wrun indicator can read every order‑book level (up to 500 a side) and read every listed options contract with greeks, including implied volatility and skew by tenor, while asserting Pine reads only top‑of‑book on 1‑tick charts (vendor claims) (see the wrun‑vs‑Pine page). The docs also include a cookbook of 47 complete example indicators to study or adapt (see the wrun docs). The plan page’s FAQ calls user scripts “kScripts”, while the documentation calls the language wrun; this review uses wrun.

Alerts and automation: cloud‑run, publish‑required

OpenMarket supports alerts on price, odds (prediction‑market odds) and custom scripts, delivering to Telegram, Discord, email or a webhook (vendor claim). Under the hood, an alert runs a published version of your indicator on OpenMarket’s servers; indicator alerts require a published build of the script (docs: alerts function). This model detaches alerts from your browser uptime but ties automation to the vendor’s cloud and the script‑publishing step. The site does not post a service‑level commitment for alert delivery on the cited page.

Markets and data scope

Per the homepage, OpenMarket carries 4,000+ crypto perps/spot pairs across 29 venues; 5,500+ NYSE/Nasdaq stocks and ETFs; CME Group futures; crypto and CME options from seven venues with IV/skew; 1,200+ FX pairs plus metals; live odds from prediction markets; and 5,600+ economic data series from 40 publishers, for 16,000+ total markets/data series (vendor totals) (see the homepage). The vendor also states trade‑by‑trade data from venues is aligned to one clock and displayed live in the browser (vendor claim). On CME futures only OpenMarket’s official indicators run; user drafts and other authors’ indicators do not, and Run is paused on CME markets (wrun docs).

Performance & reliability

OpenMarket does not post latency or uptime metrics on the cited pages, and this review did not run any tests. The vendor emphasizes a unified event timeline for trade‑by‑trade data across venues, which speaks to data handling rather than a measured result here. No service‑level commitment for alert delivery is posted on the alerts documentation page.

Setup & broker/exchange connection

Perps execution uses Hyperliquid via Wallet Execution. You connect a wallet; OpenMarket generates a Hyperliquid trading key that is created and stored in your browser and expires no later than 180 days after authorization (Terms: openmarket.xyz/terms). Wallet Execution is unavailable to “Restricted Persons,” which include residents of the United States and Malaysia; charts and analytics remain available (Terms).

US stocks and ETFs execution uses Brokerage Execution with a supported Alpaca Securities LLC account. The Terms describe Alpaca Securities LLC as a registered broker‑dealer and member of FINRA and SIPC, and state that OpenMarket is not affiliated with it. Orders go directly from your browser to the brokerage; OpenMarket says it does not route, aggregate, hold, delay, or transmit orders through its own systems. Brokerage account eligibility is decided by the brokerage, not OpenMarket (Terms).

Evidence

Facts in this review come from OpenMarket’s public pages and wrun documentation: homepage/features and market totals (see the homepage), alerts behavior (see the alerts docs), wrun syntax and strategy constraints (wrun introduction; wrun strategies overview), plan limits (the wrun limits page), and Terms for execution, security and restrictions (see the Terms).

Risks & limitations

• Costs outside the plans: Plus is $29 per month billed annually ($35 monthly), but CME real-time data (from $7 per month) and API access are priced separately.
• Free plan caps: 3 data indicators (plus unlimited classic ones), 2 indicator alerts, and 100 saved scripts can constrain complex layouts or heavy iteration (limits page).
• Simulated strategies: wrun strategies run in the Strategy Tester and never place real orders; automation from strategies is not supported (docs).
• Jurisdiction limits: Wallet Execution is not available to Restricted Persons, including residents of the United States and Malaysia; only charts/data remain (Terms).
• Narrow execution venues: perps execution is via a single DEX (Hyperliquid); US equities execution is via one listed broker (Alpaca Securities LLC) (Terms).
• US stock data timing: the cited pages do not state whether NYSE/Nasdaq data is real‑time or delayed.
• No native mobile app: the vendor says there is no native iOS or Android app; the platform works in a mobile browser, and desktop or tablet is recommended for complex analysis.
• CME futures: only OpenMarket’s official indicators run there; custom wrun scripts do not (docs).
• Identity naming inconsistency: Terms name the operator as Thalamus Technologies, Inc. (Delaware) while the homepage footer shows “Openmarket Labs”.
• Risk: trading futures, perpetual contracts and stocks is high‑risk; charts and alerts do not reduce it.

How OpenMarket compares

• TradingView remains a common charting hub for mainstream equities and a large community of script authors; for a price/markets/scripting/order‑flow comparison, see OpenMarket vs TradingView.
• TakeProfit is another browser terminal with its own scripting language (Indie) and non‑expiring cloud alerts on a single paid plan; its Freeroll tier allows only 1 alert valid for 3 months, and Binance and Exness routing is listed as in development. For wrun vs Indie, alerts and execution trade‑offs, see OpenMarket vs TakeProfit.
