Release Date: March 02, 2026

With this release we have implemented an enhancement to the unrealized gain/loss calculation for Equity Options. The Desktop Platform now uses the Bid & Ask mid-point price to determine the current market value of open option positions.

This update provides a more accurate and balanced valuation of open positions, particularly for equity options that trade infrequently or are deep in the money or deep out of the money, where the last traded price may be stale or not reflective of current market conditions. By using the mid-point price, unrealized gain/loss figures more closely align with the prevailing bid-ask market, improving transparency, reliability, and overall customer confidence in reported valuations.

Enhancements
TS-30836 Platform: Unrealized gains for Equity Options are calculated using the bid and ask midpoint price.
TS-30894 Platform: The Position P/L, Position Value, Position P/L %, and Position P/L % Grad Studies have been enhanced to use the bid and ask midpoint price in Equity Options calculations.
Help
TS-30927 Help: The documentation for Position P/L, Position Value, Position P/L %, and Position P/L % Grad Studies has been updated.
