# Position Calculator - TradingView Pine Script v5
## Overview
A robust, user-centric position sizing calculator engineered for risk management in leveraged trading (cryptocurrencies, futures, forex). This indicator computes the optimal position size based on your predefined entry price, stop-loss level, maximum acceptable loss, and leverage ratio—empowering traders to control risk exposure with mathematical precision.

## Core Functionality
This script automates disciplined position sizing to mitigate trading risks by:
1. Capturing 4 core trading parameters:
- Entry Price: The price at which you plan to open a trade
- Stop Loss: Your predefined risk-limiting price level
- Max Loss (USDT): The maximum capital you are willing to lose on a single trade (minimum: 0.01 USDT)
- Leverage: The leverage multiple used for the trade (minimum: 1x)

2. Calculating position size via a proven risk-based formula:
Position Size = (Max Loss / (|Entry Price - Stop Loss| × Leverage)) × Entry Price
- Uses absolute value for price difference to support both long and short positions
- Prevents division-by-zero errors (e.g., entry price = stop loss) with clear error prompts

3. Delivering intuitive, visual results:
- A fixed table panel (top-left of the chart) displays all input parameters and calculated position size
- Color-coded alerts: Green for valid results, red for invalid parameter warnings
- Console output for cross-verifying calculation results

## Key Features
- ✅ Risk-first design: Aligns position size with your maximum acceptable loss to protect capital
- ✅ Error handling: Detects invalid inputs (e.g., identical entry/stop-loss prices) and shows user-friendly messages
- ✅ High precision: Displays results with 5 decimal places for accurate position sizing
- ✅ Universal compatibility: Supports all leveraged trading products (1x+ leverage)
- ✅ Intuitive UI: Color-coded table for quick scanning of parameters and results
