Simple Perps Calculator
## Simple Perps Calculator (Long & Short)
A lightweight on-chart trade calculator that visualizes **entry, take-profit, and liquidation levels** with leverage-adjusted returns — designed for fast planning and clean charts.
This indicator automatically detects **long or short positions** based on your target price and adjusts calculations accordingly. All key levels are displayed as **colored horizontal price lines** with matching labels positioned near the price scale for easy reference.

### Features
- Entry, Take-Profit, and Liquidation price levels
- Automatic **long / short detection**
- Leverage slider up to **1000×**
- Leveraged **percent gain** calculation
- Color-coded horizontal price lines:
- 🟡 Entry
- 🟢 Take-Profit
- 🔴 Liquidation
- Adjustable label positioning (left or right of chart)
- Horizontal offset control to move labels out of the way
- Clean, minimal, non-intrusive design
---
### How to Use
1. Set your **Entry Price**
2. Set your **Target Price**
3. Adjust **Leverage**
4. Move labels using the **horizontal offset** slider if needed
If the target price is above entry, the script assumes a **long** position. If below, it assumes a **short** position and places the liquidation level above entry automatically.

### Notes
- Liquidation price uses a simplified isolated-margin model
- Intended for **planning and visualization only**
- Actual exchange liquidation prices may vary due to fees and maintenance margin requirements
