Evaluating Foreign Exchange Data APIs for Real-Time Trading
Summary
The article compares several foreign exchange data API providers and describes iTick’s advertised features, including free low-frequency access, coverage of currency pairs and indexes, real-time quotes, and technical support. It explains how developers might use historical bars for analysis and WebSocket streams for live quote updates, with examples centered on EUR/USD. These are data access and integration concepts rather than a defined trading strategy.
The comparison and performance claims are promotional, with no independent latency measurements, reliability statistics, pricing details, or controlled evaluation. The examples show how requests are structured but do not assess data quality, licensing, slippage, or whether the feed is suitable for a particular trading venue. Treat the claims as provider descriptions and verify service limits and data characteristics before relying on them in research or execution.
