Trade Version

Calypso provides extensive version control and audit facilities through the audit mode. A firm chooses what types of data to audit. For example, a firm can audit reference data and trade data but not market data. When a firm decides to audit a type of data, Calypso tracks every change to each piece of data of that type.

Users can:

•

See old and new versions side-by-side

•

See a trade as it existed at a particular point in time

•

Compare changes on a field-by-field basis to see each field that changed, who made the change, when, what the old value was, and what the new value is

 

The ability to reconstruct a trade as it existed in the past is useful not just for audit and control, but also for P&L attribution: is a P&L change due to changing market conditions or to corrections to the trade details?

The version number of a trade is only incremented if data has changed on the Trade. If you save a trade twice without making any modifications, the trade version number will remain the same.

 Ⓘ   [NOTE: If the environment property TRADE_VERSION_INC is true, the version number of a trade will be incremented each time the trade is saved, whether trade data has changed or not]
