OPEN-SOURCE SCRIPT
Aggiornato Lot Size + Margin Info

This indicator is designed to give Futures & Options traders instant access to lot size and estimated margin requirements for the instrument they are viewing — directly on their TradingView chart. It combines real-time symbol detection with a built-in, regularly updated margin lookup table (sourced from Kotak Securities’ published margin requirements), while also handling fallback logic for unknown or unsupported symbols.
---
### What It Does
* Automatically Detects the Instrument Type
Identifies whether the current chart’s symbol is a futures contract, option, or a cash/spot instrument.
* Shows Accurate Lot Size
For supported F\&O symbols, it fetches the correct lot size directly from exchange data.
For options, it retrieves the lot size from the option’s point value.
For cash/spot symbols with linked futures, it uses the futures lot size.
* Calculates Estimated Margin
* For futures: `Lot Size × Current Price × Margin%` (Margin% sourced from the internal lookup table).
* For options: `Lot Size × Current Price` (simple multiplication, as options margin ≈ premium cost).
* For unsupported or non-FnO symbols: Displays "No FnO".
* Fallback Margin Logic
If a symbol is missing from the margin lookup table, the script applies a user-defined default margin percentage and highlights the data in orange to indicate it’s using fallback values.
* Debug Mode for Transparency
A toggle to display the exact symbol string used for fetching lot size and margin, so traders can verify the data source.
---
### How It Works
1. Symbol Normalization
The script standardizes symbol names to match the margin table format (e.g., converting `"NIFTY1!"` to `"NIFTY"`).
2. Type-Based Handling
* Futures – Uses point value for lot size, applies specific margin % from the table.
* Options – Uses option point value for lot size, margin is simply premium × lot size.
* Cash Symbols with Linked Futures – Attempts to find and use the associated futures contract for lot/margin data.
* Unsupported Symbols – Displays `"No FnO"`.
3. Margin Table Integration
The margin % table is manually updated from a reliable broker’s margin sheet (Kotak Securities) — ensuring alignment with real trading conditions.
4. Customizable Display
* Position (Top Right / Bottom Left / Bottom Right)
* Table background color, text color, font size, border width
* Editable label text for lot size and margin display
* Toggleable lot size and margin sections
---
### How to Use
1. Add the Indicator to Your Chart – Works on any NSE Futures, Options, or Cash symbol with linked F\&O.
2. Configure Display Settings – Choose whether to show lot size, margin, or both, and place the info table where you prefer.
3. Adjust Fallback Margin % – If you trade less common contracts, set your default margin % to reflect your broker’s requirement.
4. Enable Debug Mode (Optional) – To see the exact symbol source the script is using.
---
### Best For
* Intraday & Positional F\&O Traders who need instant clarity on lot size and margin before entering trades.
* Options Sellers & Buyers who want quick cost estimates.
* Traders Switching Symbols Quickly — saves time by removing the need to check the broker’s margin sheet manually.

💡 Pro Tip: Since margin requirements can change, keep the script updated whenever your broker revises margin data. This version’s margin table is updated as of 13-08-2025.

Note di rilascio
## Lot Size + Margin Info – F\&O, Options & Commodity Margin Display ToolThis indicator gives traders instant access to the lot size and estimated margin requirements for NSE Futures & Options and MCX Commodities — directly on their TradingView chart.
It pulls from two reliable, manually updated data sources:
* Equity & Index Margins – Kotak Securities margin sheet
* Commodity Margins – MCX margin data from the official commodity source
With built-in logic to handle unknown symbols, fallback percentages, and real-time price integration, this script saves traders from constantly checking broker websites.
---
### What’s New in This Version
* Commodity Margin Support Added
Includes margin % for popular MCX contracts like Gold, Silver, Crude Oil, Natural Gas, Copper, Aluminium, Zinc, Lead, Cotton, and more.
* Separate Update Blocks
Margins are stored in two distinct, clearly labeled sections — one for Equities & Indices and one for Commodities — so future updates won’t overwrite unrelated data.
* Consistent Fallback Handling
Works the same way for equities and commodities when a symbol is not in the margin table.
---
### How It Works
1. Symbol Type Detection
* Futures (Equity, Index, or Commodity)
* Options (Equity or Index)
* Cash/Spot symbols with linked futures
2. Lot Size Retrieval
* For futures: uses the instrument’s point value from exchange data.
* For options: uses point value to get correct contract size.
* For commodities: uses MCX contract specifications.
3. Margin Calculation
* Futures & Commodities:
`Lot Size × Current Price × Margin%` (from the correct lookup table).
* Options:
`Lot Size × Current Price` (approx. premium cost).
* For symbols not in the list: applies user-defined default margin % (highlighted in orange).
4. Clear Data Organization
* Equity & Index Margins and Commodity Margins are stored in separate sections for easy maintenance.
* Both include a “last updated” date to avoid stale data.
---
### Key Features
* One-Click Lot Size & Margin Lookup for NSE F\&O & MCX commodities.
* Fallback Margin Setting so you can handle any missing symbol without delay.
* Customizable Display: Position, colors, font size, and text labels.
* Debug Mode to show the exact symbol used for fetching lot size/margin.
---
### How to Use
1. Add the Indicator to your chart (works with NSE & MCX symbols).
2. Select Display Options: show lot size, margin, or both.
3. Check the Margin % — colored white if exact, orange if fallback.
4. Update Data periodically — equities from Kotak Securities, commodities from MCX source.
---
💡 Pro Tip: Use this on both F\&O charts and MCX commodity charts to plan position sizing instantly without switching to your broker’s site.
