Symbol Lot Sizer

This EA gives traders a clean, full-window view of how large a position each Market Watch symbol can support at different percentages of account balance used as margin. It helps you quickly compare sizing options across symbols and risk levels without ever placing or modifying orders. The goal is simple position-size awareness so you can decide exposure before you trade.

Benefits

• Shows lot size potential across Market Watch symbols at up to three different % of balance margin levels side-by-side.
• Lets you show or hide any of the % columns and the Max Lot column so you only see the risk views you want.
• Display only — never places, modifies, or closes orders.
• Click any symbol to open its chart instantly.
• Full-window table with color palette cycling and adjustable font/size for quick visual scanning.
• Optional free-margin cap keeps the calculated lots realistic for the current account.

Limitations

• Lots are based on margin required (not stop-loss or pip risk).
• Accuracy depends on the broker’s margin data for each symbol.
• Limited to the number of Market Watch symbols you set.
• Takes over the chart while running (chrome is hidden; restored when removed).
• Does not account for existing open positions or pending orders in the lot math.
