Tradier review

Tradier is a hosted brokerage service with a trading API, not a library or a self-hosted trading server. It puts brokerage accounts, trading tools and API access in one vendor-operated service. A developer can build an application that connects to Tradier’s brokerage infrastructure; traders can also use Tradier’s own web, mobile and desktop tools.

That puts Tradier in the brokerage and execution layer of a trading stack. It can support products that need to connect users’ trading activity to a brokerage account, as well as individual traders who want tools and API access. Tradier’s homepage lists stocks, options, futures, forex and crypto. It also says trades and positions sync across Tradier platforms in real time. The homepage describes APIs for building, testing and scaling platforms, and links to API documentation. It does not name particular programming languages or SDKs, so check those details before choosing an implementation.

Tradier’s homepage presents its APIs as a way to create, test and scale trading platforms, and links to API documentation. It does not name an API protocol, SDK, programming language, webhook interface or plugin model. Confirm SDK and language support in the vendor’s docs before committing to a stack; the published integration surface is Tradier’s API and its hosted brokerage service.

The homepage also lists a Tradier MCP Server that works with Claude Code, Cursor and Gemini CLI, without a custom environment. That gives developers a route to use Tradier with those tools, but the homepage does not describe the server’s operations, authentication, permissions or deployment details. Tradier says more than 100 partner platforms are connected, and invites developers to become partners and integrate brokerage services into their own platforms. Treat those partner integrations as a separate path from building directly against the API, and verify the applicable onboarding and commercial terms with Tradier.

Lite costs $0 per month and includes web, mobile and API access. That is not a zero-cost trading plan: the listed rate is $0.35 per stock trade and $0.35 per equity, ETF or index options contract. Pro costs $10 per month, with $0 stock and equity/ETF options trades, while index options cost $0.35 per contract. Pro Plus costs $35 per month; its listed index options rate is $0.10 per contract, and futures micros cost $0.25 per contract.

Tradier’s pricing page lists a two-month Pro or Pro Plus offer for new customers with a $500 minimum deposit. Subscriptions bill monthly on the signup date; annual billing is not listed. Futures also carry a $0.35 per-contract exchange, regulatory and clearing/routing fee. CQG costs $10 per month and Rithmic $25 per month. The vendor does not publish API request pricing or an overage schedule on the homepage, so ask about rate limits and any developer-specific charges before estimating production costs.

Tradier is presented as a hosted brokerage and API service. Its homepage does not identify an open-source licence or a self-hosted deployment option. If your architecture requires running the brokerage integration inside your own environment, ask Tradier whether that is supported and review its terms before building around the service.

An integration would depend on Tradier’s brokerage and API, so moving away would mean implementing another broker’s connection and handling account and trading workflows there. Tradier’s homepage does not describe data export formats or a migration process. Ask the vendor what account, position, order and history data you can export, in which formats, and whether API access or data retention changes when an account closes. Keep your own application records where your product and regulatory obligations allow.

Before production, confirm current API request limits, authentication and permission controls, service availability commitments, and how Tradier handles market-data entitlements. The homepage links to API documentation but does not state rate limits or an uptime commitment. A Reddit thread reports a stated limit of 120 calls per minute, while one user says their script reached about 800; that is an anecdote, not a safe operating limit. Confirm the current rules with Tradier rather than designing around that report.

Trader reports are mixed. Some Reddit users describe automated trading as a good fit, while others call the interface awkward or report buggy behavior and poor fills. Those are individual accounts, not a reliability measurement, but they make execution testing important. For a product that routes customer orders, also review account-data handling and the regulatory classification of the alert-to-execution flow with qualified counsel; a Reddit commenter specifically raises FINRA Rule 4512 as a point to review. Test failure handling and reconciliation before relying on live orders.
