Trade Calculator 🧮 {Phanchai} — Documentation

A lightweight sizing helper for TradingView that turns your risk per trade into an estimated maximum nominal position size — using the most recent chart low as your stop reference. Built for speed and clarity right on the chart.

Key Features

• Clean on-chart info table with configurable font size and position.
  
• Row toggles: show/hide each line (Price, Last Low, Risk per Trade, Entry − Low, SL to Low %, Max. Nominal Value in USDT).
  
• Configurable low reference: Last N bars or Running since load.
  
• Low label placed exactly at the wick of the lowest bar (no horizontal line).
  
• Custom padding: add extra rows above/below and blank columns left/right (with custom whitespace/text fillers) to fine-tune layout.
  
• Integer display for Risk per Trade (USDT) and Max. Nominal Value (USDT); decimals configurable elsewhere.
  
• Open source script — easy to read and extend.
  

How to Use

1. Add the indicator: open TradingView → Indicators → paste the source code → Add to chart.
   
2. Pick your low reference in settings:
   
   • Last N bars — uses the lowest low within your chosen lookback.
     
   • Running since load — tracks the lowest low since the script loaded.
     
   Set your capital and risk:
   • Total Capital — your account size in USDT.
     
   • Max. invest Capital per Trade (%) — your risk per trade as a percent of Total Capital.
     
   Tidy the table:
   • Use Table Position and Table Size to place it.
     
   • Add Extra rows/columns and set left/right fillers (spaces allowed) for padding.
     
   • Toggle individual rows (on/off) to show only what you need.
     
   Read the numbers:
   • Act. Price in USDT — current close.
     
   • Last Low in USDT — stop reference price.
     
   • Risk per Trade — whole-USDT value of your risk budget for this trade.
     
   • Entry − Low — absolute risk per unit.
     
   • SL to Low (%) — percentage distance from price to low.
     
   • Max. Nominal Value in USDT — estimated max nominal position size given your risk budget and stop at the low.
     

Scope

• This calculator is designed for long trades only (stop below price at the chart low).
  

Notes & Assumptions

• Does not factor fees, funding, slippage, tick size, or broker/venue position limits.
  
• “Running since load” updates as new lows appear; “Last N bars” uses only the selected lookback window.
  
• If price equals the low (zero distance), sizing will be undefined (division by zero guarded as “—”).
  

Risk Warning
Trading involves substantial risk. Always double-check every value the calculator shows, confirm your stop distance, and verify position sizing with your broker/platform before entering any order. Never risk money you cannot afford to lose.

Open Source & Feedback
