Evaluate the operating model behind the vendor choice
Selecting buy-side trading technology is not only a feature comparison. Firms need to examine the points where investment, order, execution, data, analytics and post-trade processes meet. A strong evaluation should show how each vendor would support today’s operating requirements and what changes would be needed as users, asset classes, brokers and volumes increase.
What to test before selecting a vendor
Assess the investment-to-order path
Review how portfolio decisions, target positions, model changes, restrictions and approvals move into order creation. A strong evaluation should test where PMS and OMS processes require manual intervention, duplicate checks or duplicate data entry.
Assess post-trade execution review
Look closely at how the EMS or OEMS handles fills, partial fills, cancels, rejects, allocations, broker updates and execution status. Firms should understand how traders, investment teams, compliance and operations review activity after orders are routed or completed.
Assess how the setup handles change
Test how the provider would support new asset classes, brokers, algos, order types, users, regions, reporting needs and higher trading volumes. Vendor comparisons should assess whether the workflow would require extra spreadsheets, duplicated checks or additional manual review.
