Rithmic Protocol becomes the primary Rithmic connection
New Rithmic connections now start with the server-side Rithmic Protocol path. From Connections, the first step asks for a Connect point and a searchable Rithmic system. Continue to enter your username, password, and Account start date, then choose among the accounts discovered with your credentials.

The password remains masked unless you select Show password, and inline guidance catches incomplete details before connecting. The start date must be between 2013 and today; Deltalytix retrieves history in consecutive windows of up to 30 days.

More reliable history for LucidTrading accounts
If a fill-history request returns no data, synchronization can now recover completed executions from order history using the account's own routing metadata. This addresses the zero-fill history seen by affected LucidTrading accounts without changing the guided setup.
The previous Rithmic connection no longer appears for new setups, and this release does not automatically migrate existing credentials. Rithmic Protocol still requires a configured endpoint, valid credentials, and R | Protocol entitlements from your broker or prop firm; compatibility is not guaranteed for every legacy account.
