Decoupling Trading Data: MT5 to PostgreSQL Low-Latency Architecture for Institutional FinTech
Diana Sterling | Enterprise Systems Architect
Overcoming Retail Constraints Data Siloing MetaTrader 5 stores data locally, creating rigid silos that prevent enterprise-wide risk analysis and cross-terminal aggregation.
Latency Bottlenecks Traditional REST API polling introduces unacceptable delays (often >300ms) for high-frequency quantitative strategies.
Analytical Limitations Proprietary quant models require a centralized, highly indexable, and easily queryable SQL environment, which native terminals lack.
