Algorithmic systems
What is API Trading and how do retail platforms (e.g., NinjaTrader, Sierra Chart) interface with automated algorithmic execution brokers?
By Easy Money Scanner · Educational reference · Not investment advice
The short answer
API trading lets retail platforms like NinjaTrader or Sierra Chart connect programmatically to broker or exchange infrastructure, enabling custom automated strategies to submit orders directly.
How it works
Retail traders code strategies against documented broker APIs, which then route orders through the broker's execution infrastructure to the exchange, subject to platform-specific latency and reliability limits.
An example
NinjaTrader's API links a custom strategy to a broker.
Risk & limitations
Retail API latency is far higher than institutional colocated systems.
