Standard-deviation Projections

What are Standard-deviation Projections?

Standard-deviation projections extend the height of a completed range in multiples above and below it, mapping where a later expansion might reach. Despite the name, nothing statistical is computed — in ICT usage one "standard deviation" equals the height of the anchor range, laddered outward in whole and half multiples (±1, ±2, ±2.5, up to ±4 in common practice). The classic anchor is a defining range from the quiet part of the forex day: the Central Bank Dealers Range (CBDR) formed in the New York afternoon-to-evening lull, the Asian range, or the "flout", a related range from the early forex material.

The premise is that expansion out of consolidation tends to travel a measured multiple of that consolidation, so the bands act as candidate zones for the coming session's high or low. Newer applications anchor the ladder to an opening range or to the manipulation leg of a session (the Judas swing) and project in the direction of the expected expansion. Either way the bands are map lines, not confidence intervals, and are normally read with structure rather than traded on contact.

How traders use it

• As session-extreme framing (the classic use): project the CBDR or Asian-range ladder before London opens and treat the outer bands as zones where the day's high or low may form. A quiet day that never reaches the first band is information too.
• As post-manipulation targets: anchor the ladder to the leg that ran the liquidity, then project deviations in the expansion direction as scale-out zones. The commonly watched multiples (−2, −2.5, −4) are convention within the methodology, not measured probabilities.
• As a confluence filter: a band that lands on a higher-timeframe level, or deep in premium or discount of the working range, is treated as far more interesting than one floating in isolation.
