Persistent Advanced Trading Settings Memory

Implement persistent advanced trading settings that remember user preferences when switching between order types (market/limit). Currently, users must manually re-select "Open By SL," choose risk multiplier, change price to pips for stop loss, and input SL pips every time they switch order types, creating a cumbersome multi-step process. The proposed solution would save and maintain these advanced trading preferences (Open By SL status, risk multiplier selection, stop loss unit preference of pips vs price, and SL amount) across order type changes, significantly streamlining the trading workflow and reducing the repetitive manual configuration required for each trade setup.
