A next-generation O/EMS should give traders current portfolio information, connected execution tools, and usable analytics within the order workflow. Heads of trading, trading COOs, and platform owners should prioritize accurate positions and cash, clear exception handling, and controls that accommodate different accounts and markets. These capabilities should reduce manual reconciliation and help traders respond when an order's requirements change.

At Equities Leaders Summit 2026, Hariharan Srinivasan, Director – Data Engineering & Portfolio Analytics at Franklin Templeton, emphasized that trading architecture needs tested recovery arrangements: "You always need to design for a fallback." His discussion addressed event logging, capacity for activity surges, and testing before migration. O/EMS evaluation should therefore examine how the connected systems behave during disruption alongside their normal execution functions.

A separate public panel highlighted the importance of updating portfolio targets while multi-day orders remain active. Changes to cash flows or account allocations can alter the quantity the desk needs to execute, so those updates must reach traders without extensive manual adjustment.

Begin the platform review with representative orders and disruption scenarios. Test whether a cash-flow change updates an active order correctly, whether account-specific controls cause unexplained delays, and whether traders can recover safely after a connection fails. Assign an owner to each exception and evaluate proposed upgrades against the manual work, execution risk, or reporting limitation they would address.

Join the upcoming Equities Leaders Summit to compare O/EMS priorities, integration lessons, and resilience practices with peers responsible for buy-side trading workflows.
