02 / READ THE BANDS
Read the range. Understand the context.
A band test or breakout gains meaning from the wider session. Read price structure, timing, participation and implied volatility together, then bring your own setup and risk rules to the move.
Define the range.
Scale annualized volatility to one session. Plot 1σ, 1.5σ and 2σ bands above and below the previous close.
±1σ · ±1.5σ · ±2σ
Keep the context.
The levels remain fixed during the session. Read price against them alongside timing and volume. The same band event can carry a different meaning in a different market context.
THE TRADER’S COCKPIT
Four instruments. One cockpit.
First, understand price and time. Volume adds the activity behind the move. Bouhmidi Bands add implied volatility: how much movement is priced in. Like instruments in a cockpit, each becomes more useful when read with the others. Understanding the current situation means bringing the whole panel into view.
Price
Understand the structure of the move.
Time
Read its timing and sequence.
Volume
Assess the activity behind it.
Volatility
Put its size against what is priced in.
