Standard Deviation Projections
Also: standard deviations, SD projections, Fibonacci standard deviations, negative standard deviation levels, institutional market structure standard deviations
Visual Context Required
This concept requires chart visuals for full understanding.
Standard Deviation Projections are price extension targets derived by anchoring a Fibonacci tool to specific price swing legs (A-to-B) and projecting the measured range as multiples of that initial range beyond the terminating point. The "negative" (extension) levels on the Fibonacci tool — negative 1, negative 1.5, negative 2, negative 3, negative 4, negative 6.5, negative 7.5, etc. — represent one, one-and-a-half, two, three, etc. standard deviations of projection beyond the range. ICT anchors the Fibonacci to: (1) the A-to-B leg of a breaker pattern (low to high for bullish, high to low for bearish), projecting where price will reach for targets. (2) Intermediate-term or long-term lows to intermediate-term highs (or vice versa) on daily/higher charts to project institutional turning points. Confluence of a standard deviation level with an existing pool of liquidity (old high, old low, buy stops, sell stops) or a higher-timeframe PD array confirms the level as a high-probability target. ICT describes these as "institutional market structure" — not in any published textbook, proprietary to his methodology. The 3:00–4:00pm final-hour macro (daily closing range) is cited as a time window where the algorithm delivers price to the final standard deviation target.
Identification6
- Identify the A-to-B price leg: for a bullish breaker, A = the low of the swing, B = the high of the swing prior to the lower-low that forms the breaker.
- Anchor Fibonacci from A (low) to B (high) for bullish projections. Drag Fibonacci from A (high) to B (low) for bearish projections.
- Standard deviation levels are the negative Fibonacci extension levels: -1, -1.5, -2, -3, -4, -6.5, -7.5.
- One standard deviation (-1) = the measured A-to-B range projected beyond B. -1.5 = 1.5x the range beyond B, etc.
- Look for confluence: does a standard deviation level coincide with an old high, old low, liquidity pool, or higher-timeframe PD array?
- For institutional market structure on daily charts: anchor from intermediate-term low to intermediate-term high (or long-term low to swing high) and project negative standard deviations as potential institutional turning points.
Entry2
- Standard deviation projections define targets, not entries. Use PD arrays (FVGs, order blocks, breakers) within the A-to-B range for entry.
- When the target standard deviation coincides with a higher-timeframe liquidity pool, it confirms the higher-probability exit level for a trade entered on the breaker or within the A-to-B leg.
Stop1
- Stops are placed relative to the entry PD array, not the standard deviation projection.
Target4
- Easiest bread-and-butter target: -1 standard deviation (one measured A-to-B range projected beyond B).
- Confluence of SD level with old high/liquidity is the ideal exit point: 'that right there tells me it will definitely reach for that liquidity.'
- For TGIF retrace modeling: -2 standard deviation gives the expected weekly range pullback depth.
- Multiple SD levels (-3, -4, -6.5, -7.5) used when higher-timeframe bias and weekly volume imbalance confirm extended targets.
Invalidation2
- Standard deviation projections are targets, not support/resistance in the traditional sense — price can blow through them if higher-timeframe draw exceeds the measured level.
- A level that aligns with no liquidity or PD array is less reliable.
Inferred Conditions (Unvalidated)
- When two or more SD levels cluster near the same price (within a handle or two), that cluster is a very high probability target zone.
- The -6.5 SD confirming a daily candle high from a specific date is ICT's signal that the level 'will definitely reach for that liquidity.'
ICT Quotes
"You're looking for a confluence of standard deviations at key market turning points. This is institutional market structure. It's not in books. It's only been taught through my mentorship."
"The final hour macro, which is three to four o'clock, the last hour trading before four o'clock closing session. That 30 minute interval is a macro, and the algorithm will do a market on close run where it spoils to a point of liquidity."
"This A to B price leg, you take that leg from high down to the low and you lay your Fibonacci on that. And then you do your standard deviations lower. Whatever this range is, from here to here, one standard deviation lower. That is the easiest bread and butter approach to using the breaker."
"If I show you the negative 6.5 standard deviation comes in at the daily high June 16, I know some of you already like managers complicated. But what I'm teaching you is we have an expectation that the market will reach up into the liquidity above this high."
"We have three standard deviations, four standard deviations, five standard deviations, six, seven and a half. Now if I show you six and a half, that's right at that old high. That right there tells me that will definitely reach for that liquidity."
"How low can it retrace with TGIF? Two standard deviations. Inside this inefficiency inside of the breaker. The standard deviation comes in at 4480.75. Folks, that's perfect."

Notes
Standard deviation projections are ICT's proprietary use of Fibonacci extension levels as price projection tools. The key insight is not in the Fibonacci itself (a common tool) but in: (1) anchoring specifically to identified A-to-B structural price legs, (2) seeking confluence of the SD level with a known liquidity pool or PD array, (3) using time (macros, daily/weekly close windows) to confirm delivery. The 3:00–4:00pm macro reference in the Feb 12 file is an early articulation of the PM session macro concept later formalized in the July 10 2023 lecture. Cross-reference: advanced-breaker-theory.yaml, time-macros.yaml.
Asymmetry Notes
Bullish projections anchor Fib from low (A) to high (B) and project negative extensions above B. Bearish projections anchor from high (A) to low (B) and project negative extensions below B. The mechanics are fully symmetrical.
