How brokers add fractional and notional trading, choose routing vs. internal inventory, and limit exposure with inventory caps, fill-from-inventory, automated closures, and pre-allocated block orders.
For broker-dealers, COOs, and platform owners planning to launch or expand fractional trading. If you’re weighing “route as received” against internal inventory and need clear risk limits, this guide shows the trade-offs.
It also fits RIAs and institutional brokers using block orders, as well as CTOs upgrading OMS and UIs for fractional and notional quantities. You’ll see where exposure can creep up and how to cap it without adding operational drag.
You’ll learn two ways to support fractional orders and how each impacts control, coverage, and fees. The book explains where risk arises when you hold inventory, and how simple rules and automation cap exposure in real time.
You’ll be able to configure workflows that round to whole shares, fill client orders from inventory when appropriate, auto-close positions beyond set limits, and run pre-allocated block orders. Use these patterns to update OMS, admin consoles, and client UIs for fractional and notional quantities.
