Supertrend AT v1.0

📌 Supertrend AT v1.0 — Strategy Overview
Overview
Supertrend AT v1.0 is a fully automated trading strategy based on the Supertrend indicator.
It identifies trend reversals and places long or short entries accordingly, with built-in position sizing, stop-loss/take-profit management, and commission-aware calculations.

🚀 Key Features
✅ Entry Signals Based on Trend Reversals

Long entry when Supertrend changes from downtrend to uptrend

Short entry when Supertrend changes from uptrend to downtrend

✅ Risk-Based Position Sizing

Calculates position size so that a stop-loss only risks a fixed percentage (RPT) of total capital

✅ Reward/Risk Ratio-Based Target Price Calculation

Take-profit price is computed not by price difference, but by actual loss and desired reward-to-risk (RR) ratio

✅ Fully Commission-Aware

Commission is factored into entry, stop-loss, and take-profit price calculations

Ensure commission settings match in both the input panel and the strategy properties tab

✅ Dual Language Support

Switch between English and Korean interface

✅ Visual Trade Levels & Info Display

Entry, stop, and target prices plotted on the chart

Real-time open PnL and equity shown in an on-screen table

⚙️ How to Use
Apply Strategy to Chart

Load the strategy and configure the following parameters in both the Input tab and the Properties tab:

Commission rate (e.g., 0.05%)

Market decimal precision (e.g., 4 for 0.0001)

Adjust Entry Parameters

RPT: Risk per trade as a percentage of your total equity (e.g., 2%)

RR: Reward-to-risk ratio (e.g., 3 = target profit is 3× the potential loss)

Choose whether to allow Long or Short trades

For Auto-Trading Integration

Make sure the minimum order size is valid for your exchange

If the calculated quantity is below the exchange's minimum unit, it may result in errors
