A Qt-based application for managing financial instruments with real-time attribute editing and dependency tracking. Supports options, swaps, and other derivative products.

• 📊 Dual-view interface:
  • Product list view (name + price)
  • Detailed attribute editor (name, value, type, default)
• ✏️ In-place editing of financial product attributes
• 🔄 Automatic dependency resolution (e.g., updating price/quantity affects total)
• 🚦 Validation and type conversion system
• ⏱️ Timestamped status messages with success/failure feedback
• 📈 Supports multiple product types:
  • Options (with strike price, expiration, volatility)
  • Swaps (with fixed rate, notional value)

• Qt6 Core & Widgets
• C++20 compatible compiler
• CMake 3.16+

Ubuntu:

sudo apt install qt6-base-dev qt6-tools-dev-tools cmake build-essential

1. Main Window

   • Displays list of financial products
   • Double-click to open detail view

2. Detail Window

   • Editable fields (Value column only)

• Dynamic Attribute System: Uses Qt meta-object system (Q_PROPERTY) for property management
• Type Safety: QMetaType conversions with fallback to defaults
• Efficient Updates: Model resetting with beginResetModel/endResetModel
• Case-Insensitive Checks: For "Total" field identification
