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
- Add the indicator: open TradingView → Indicators → paste the source code → Add to chart.
- 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.
- Total Capital — your account size in USDT.
- Max. invest Capital per Trade (%) — your risk per trade as a percent of Total Capital.
- 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.
- 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.
- Last N bars — uses the lowest low within your chosen lookback.
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.
