Lot Size Table

Lot Size Table Indicator – Pine Script (v5)
This TradingView script, “Lot Size Table,” creates a dynamic on-chart table that helps forex traders quickly calculate position sizes (lot sizes) for different capital and risk settings across various stop-loss (SL) pip scenarios.

🔧 Key Features:
📊 Real-time Forex Price Integration
Retrieves daily forex prices from OANDA for accurate lot size adjustments.

Instruments supported: USDJPY, USDCHF, AUDUSD, GBPUSD, NZDUSD, USDCAD, EURUSD.

🧠 Smart Lot Size Adjustments
Custom function adjustLotSize() adjusts lot sizes based on:

The currency of the instrument (e.g., JPY, GBP, AUD, etc.).

Special multiplier for symbols like US30 (e.g., ×8.5).

🧾 Flexible Capital & Risk Inputs
Supports 3 customizable capital groups, each with its own:

Capital amount

Risk percentage

📉 Multiple Stop-Loss (SL) Scenarios
Users input a comma-separated list of SL pip values (e.g., "20,25,30,...").

For each SL value, lot sizes are calculated for all 3 capital/risk combinations.

📋 Formatted On-Chart Table
Displays in a user-selected corner of the chart.

Customizable size, background color, and border.

Header row includes capital values and risk % (formatted to "k" if over 1,000).

Remaining rows show calculated lot sizes for each SL pip value.

📐 How It Works:

Lot size = (capital × risk%) / (SL pips × 10)
