Episode notes
Founder Story From Calculator To Interactive Brokers
- Thomas Petterfi built early automated handheld pricing tools to trade options on the exchange floor.
- He went from a programmable calculator at a highway firm to founding Timber Hill and later launching Interactive Brokers in 1993 after turning his trading tech into a product.
Smart Order Routing Drives Better Execution
- Interactive Brokers' proprietary smart routing scans multiple venues and dynamically routes parts of an order to secure the best execution.
- That routing can result in buys at prices better than the limit and prevents the broker from capturing extra spread like single-market routing brokers do.
Automated Margin Monitoring Cuts Risk And Headcount
- IBKR automates margin evaluation and real-time liquidations with a color-coded cushion indicator to warn customers.
- This fully automated process contrasts with many brokers' manual margin calls, reducing risk and operating headcount.
