Calculation limits

• The command does not accept a cmd/side field. The current handler leaves the trade command at its default value (0, OP_BUY), so the calculation follows the BUY price-difference branch.
• It verifies the login exists, but does not read the account group currency or convert the result into that currency.
• The result is raw instrument PnL. It does not include commission, storage, account-currency conversion, or final money rounding.
• For quote-based floating P/L in the terminal and Backoffice, see Profit valuation and currency conversion. This command does not provide a per-position quote-update stream.
