This update adds an optional proprietary trading firm mode while preserving the core logic of SigmaTau Index EA.

Main changes:

New Proprietary Trading Firm configuration section.
Preconfigured profiles for FTMO, Topstep, Apex, and FundedNext.
Custom mode to adjust rules for any prop firm.
Maximum daily loss control.
Static, intraday trailing, or EOD trailing total drawdown control.
Safety buffer before rule violation.
Automatic blocking of new entries when critical rules are reached.
Option to close only EA positions or the entire account in case of violation.
Projected risk protection before opening new trades.
Profit target, minimum trading days, daily consistency, and daily trade limit controls.
Panel updated with prop firm mode status.
Set files updated for the new version while preserving existing parameters.
By default, prop firm mode is disabled, so the EA’s original behavior is preserved until the user enables and configures this protection.
