Cboe Charges More for Dusty Old Trading Tech Relics
Published Date: 3/31/2025
Notice
Summary
Starting April 1, 2025, Cboe Exchange is raising fees for its older Silexx trading platforms, called the Legacy Platforms. Traders and firms using these versions will see the new prices kick in right away. This change helps Cboe keep up with costs and improve services for everyone.
Analyzed Economic Effects
3 provisions identified: 1 benefits, 2 costs, 0 mixed.
Monthly Login Fee Increases
If you use Cboe's Legacy Silexx platforms, starting April 1, 2025 the Exchange raises the monthly fee per Login ID as follows: Basic from $500 to $625, Pro from $500 to $625, Pro Plus Risk from $750 to $950, and Buy-Side Manager from $375 to $475.
Fee Hike Aims to Push Migration
The Exchange states the higher Legacy Platform fees are intended as an incentive for market participants to transition to the current Cboe Silexx and Silexx FLEX versions; the Legacy Platforms are being actively transitioned away and will be decommissioned at a future to-be-determined date.
Platform Use Is Voluntary
The Exchange notes use of the Legacy Platforms is voluntary and not compulsory, and market participants may continue to use other order entry and management systems or execute orders without the platform.
