📐 Pine Script V6 Position Size Calculator: Full Description

This Pine Script v6 indicator is a simplified, universal position size calculator designed for traders to quickly determine the exact quantity of an asset (shares, crypto units, etc.) they should trade to maintain a specific risk tolerance. It focuses solely on the most common and accessible calculation method: determining the number of units/contracts.

1. 🎯 Purpose

The primary goal of the script is to answer the question: "Given my total account capital and a defined stop-loss price, how many units of this asset can I buy/sell while only risking a specified percentage of my capital?"

It uses the classic position sizing formula:
Position Size (Units)=Risk Per UnitAccount Risk Amount​

2. ⚙️ Indicator Settings (Inputs)

The script provides the user with five key adjustable parameters, all located in the indicator's settings panel:
Parameter Type Default Value Description
Capital total ($) float 10000.0 Your total trading account balance. This is the basis for calculating the risk amount.
Risque par trade (%) float 1.0 The maximum percentage of your capital you are willing to lose on this specific trade.
Prix d'Entree float 150.0 The target entry price for the trade. Since the "use current price" option was removed, this manual price is always used.
Prix Stop Loss float 145.0 The protective stop-loss price where you will exit the trade.
