Is OpenMarket cheaper than ChartingLens?

OpenMarket and ChartingLens both quote USD prices, but their paid plans are structured differently, so this comparison does not name a cheaper option. On OpenMarket's plan page, Plus costs $35 per month billed monthly or $29 per month billed annually ($348 per year), and the page showed identical USD prices for guest sessions from 10 countries; checkout pricing was not tested. ChartingLens lists Premium at $14.99 per month or $149 per year and Pro at $29.99 per month or $299 per year on its pricing page. Both keep a free plan, and ChartingLens states its Free plan costs $0 with no card required. OpenMarket also lets users unlock Plus without paying: $100k traded on Hyperliquid through the platform in 30 days earns 31 days of Plus, or an OpenMarket+ code can be redeemed. ChartingLens states there is no separate Premium trial. OpenMarket's Data API is priced separately from its plans. Last checked in October 2026 on the vendors' own pages.

Do OpenMarket and ChartingLens support custom indicator code?

OpenMarket supports custom indicator code through wrun, a scripting engine that uses TypeScript syntax in an AssemblyScript dialect, while ChartingLens lists no scripting language of its own. According to OpenMarket's documentation, a wrun indicator is compiled to WebAssembly and runs in the user's sandboxed browser, or on OpenMarket's servers when the code is protected, and wrun strategies place simulated orders only. ChartingLens instead offers custom indicators described in plain English, and Premium and Pro can paste a Pine Script indicator or a ThinkScript study to convert it into a native indicator. OpenMarket's assistant Kata also writes an indicator from a description. Both run in the browser and neither lists a native iOS or Android app: OpenMarket is optimised for desktop and tablet browsers, and ChartingLens states it is responsive on smartphones and tablets. ChartingLens adds a multi-window mode on Premium and Pro for multi-monitor setups. Last checked in October 2026.
