Accurate Volatility Indicator

A more grounded way to evaluate how a stock actually moves

What This Indicator Does

Many retail brokerage platforms don’t have an out-of-the-box solution for volatility analysis.

That’s why Dan created the Accurate Vol Chart indicator for thinkorswim.

It plots:

  • 30-day Implied Volatility (IV)

  • 21-day Historical Volatility (HV)

on the same lower indicator—so you can see both, side by side.

The time periods are aligned to reflect roughly one month of trading activity, giving you a more cohesive view of how the stock is actually moving.

Why This Matters

Instead of relying on generalized volatility measures, you’re seeing how implied expectations compare to actual movement.

That makes it easier to:

  • evaluate positions in context

  • see how current conditions compare to recent behavior

  • interpret volatility in a way that’s directly usable
