Today Range Calculator
1. Indicator Name
Today (Today’s Volatility)
2. One-line Introduction
Displays real-time 30-day historical volatility (HV30) as a compact table on the chart, helping traders instantly assess market risk levels.
3. General Overview
Today ↑↓ is a lightweight informational widget that calculates and displays the 30-day Historical Volatility (HV30) of the asset in real time.
Using logarithmic returns over the past 30 periods, the script computes variance and then annualizes it to express volatility as a percentage (%) per year.
The result is shown in a clean 1x1 table cell, which can be positioned anywhere on the chart—top/bottom, left/right—depending on your preference.
This makes it easy to quickly evaluate whether the current market is high-risk (volatile) or stable, without cluttering the chart.
It’s especially useful for position sizing, risk management, volatility-based entry/exit decisions, and as a filter for breakout strategies.
Built with performance in mind, the script uses minimal system resources and can be used alongside any indicator or strategy without interference.

📘 Indicator User Guide
📌 Basic Concept
Today ↑↓ calculates 30-day Historical Volatility (HV30) by analyzing the asset’s log returns over the past 30 bars.
The result is annualized and shown as a percentage to reflect volatility in standardized terms.
Useful for gauging risk levels and strategy suitability in current market conditions.
⚙️ Settings Explained
Table Position: Choose where the volatility table appears:
Top Left / Top Right / Bottom Left / Bottom Right
📈 High Volatility Example
HV30 > 50% indicates a volatile environment
Suggests wider stop-losses, cautious position sizing, or favoring breakout strategies
📉 Low Volatility Example
HV30 < 15% suggests a calm market or range-bound behavior
Useful as a signal for upcoming volatility expansions or breakout preparations
🧪 Recommended Use Cases
Position Sizing: Scale position size based on HV30 readings
Strategy Filter: Activate certain systems only when volatility meets predefined conditions
Breakout Timing: Identify low-volatility zones as potential breakout opportunities
🔒 Precautions
This indicator does not generate buy/sell signals; it is a volatility reference tool
HV thresholds vary across asset classes—adjust interpretation accordingly
Since HV30 is historical, it may lag during rapid market changes
