Overview

Ontology Trading develops AI-powered algorithmic trading tools that help traders turn market ideas into automated strategies. Its platform combines real-time market data, AI-assisted strategy design, and broker-connected trading workflows. By connecting to TradeStation through the Connect Trade API, Ontology Trading saved approximately $100,000 in market data costs and months of development time by eliminating the need for a separate market data vendor.

The Challenge

For algorithmic trading platforms, real-time market data is non-negotiable, but sourcing it independently is expensive and slow. Contracting directly with a third-party market data vendor typically costs in the range of $100,000 or more annually, and requires months of development time to negotiate a vendor contract, integrate a separate API, and normalize that data alongside broker connectivity. That is two integration projects where there could be one.

The Solution

Instead of contracting with an independent market data vendor, Ontology Trading connected to TradeStation through the Connect Trade API. Because Connect Trade's market data API is native to its broker connectivity layer, Ontology Trading accessed TradeStation market data and trading execution through a single integration, eliminating the need for a separate vendor contract and a separate API integration entirely.

Results

Approximately $100,000 saved by accessing broker-sourced market data through Connect Trade rather than contracting with an independent market data vendor
Months of development time saved by eliminating the need to source, negotiate, and code to a separate market data API
Single integration replaced what would have been two parallel infrastructure projects
Unified architecture: market data and broker connectivity operate through one API, reducing ongoing maintenance overhead

Connect Trade enables fintech platforms to add brokerage connectivity through a single API rather than building direct integrations to brokers such as Interactive Brokers, Fidelity, Schwab, Webull, Tastytrade, and TradeZero.
