Position Sizer and Calculator (PSC)
A professional-grade position sizing and risk evaluation tool designed to quantify trade exposure directly from chart-defined levels.
This script calculates trade size, risk, reward, and performance metrics dynamically based on your selected Entry, Take Profit, and Stop Loss levels.
It is designed for disciplined traders who manage capital allocation through structured risk control.

Overview
The Position Sizer and Calculator operates on a capital-allocation model.
The trader defines the total dollar amount intended for the position. Risk is then derived automatically from the selected Stop Loss level. All outputs update in real time as Entry, TP, or SL levels are adjusted on the chart.
This ensures immediate visibility into:
Position size
Dollar risk
Risk percentage
Profit potential
Risk/Reward ratio

Calculation Methodology
The script uses the following formulas:
Shares Quantity
Qty = Trade Value ÷ Entry Price
Risk per Share
Risk per Share = |Entry − SL|
Total Risk (Dollar Risk)
Risk = Risk per Share × Qty
Risk Percentage of Trade Value
Risk % = (Risk ÷ Trade Value) × 100
Reward per Share
Reward per Share = |TP − Entry|
Profit at Target
Profit = Reward per Share × Qty
Risk/Reward Ratio
R:R = Reward per Share ÷ Risk per Share
All risk and reward calculations use absolute price distances to ensure correct handling of both long and short configurations.

Table Output
The summary table displays the following metrics in structured order:
Trade Value
Shares Quantity
Entry
Take Profit
Stop Loss
Profit at Target
Risk (Dollar Risk)
Risk % (of Trade Value)
Risk/Reward Ratio
Values update immediately when price levels or trade value are adjusted.
---
Structural Controls
The script enforces logical trade structure:
TP and SL cannot both be above Entry.
TP and SL cannot both be below Entry.
Risk is always derived from the Stop Loss.
Long and short configurations are automatically detected.
