User Interface Overview
Main Tab
The Main tab is the core of the Expert Advisor. It displays essential trade information such as position size, risk, reward, and risk-to-reward ratio. Traders can quickly switch between long and short positions, adjust entry and exit levels, define risk, and view the final calculated position size in real time.

Risk Tab
The Risk tab evaluates both current and potential portfolio risk by analyzing open positions and pending orders. It provides a clear overview of total exposure, helping traders avoid over-leveraging their accounts.

Margin Tab
This tab displays detailed margin information, including required margin for the calculated trade, future used margin, free margin after trade execution, and the maximum allowable position size based on leverage.

Swaps Tab
The Swaps tab shows complete rollover details for the selected instrument, including daily and yearly swaps for both long and short positions, calculated per lot and per position size.

Trading Tab
The Trading tab allows traders to execute trades directly from the panel using the calculated position size. It also includes advanced trade management options such as trailing stop, breakeven, slippage control, spread limits, and trade confirmation.
