Formula

SD Projection = Asia High + (n x Asia Range) or Asia Low - (n x Asia Range)

The Asia Range = Asia High - Asia Low. Standard deviation projections multiply the range by n (1, 1.5, 2, 2.5) and add above the high or subtract below the low. CBDR expansion targets use the same range as the projection unit. Judas Swing levels are typically 0.5 SD beyond the range boundaries.

Worked Examples

Example 1: EURUSD Asia Range with CBDR Projections

Problem:Asia High: 1.0880, Asia Low: 1.0850, ADR: 80 pips. Calculate range, SD projections, and Judas Swing levels.

Solution:Range = 1.0880 - 1.0850 = 0.0030 (30 pips)\nMidpoint = (1.0880 + 1.0850) / 2 = 1.0865\n1 SD Up = 1.0880 + 0.0030 = 1.0910\n1.5 SD Up = 1.0880 + 0.0045 = 1.0925\n2 SD Up = 1.0880 + 0.0060 = 1.0940\n1 SD Down = 1.0850 - 0.0030 = 1.0820\nJudas Swing (bullish) = 1.0850 - 0.0015 = 1.0835\nRemaining ADR = 80 - 30 = 50 pips

Result:30 pip range | 50 pips remaining | 2 SD targets: 1.0940 / 1.0790

Example 2: Narrow Asia Range - High Expansion Potential

Problem:Asia High: 1.2550, Asia Low: 1.2535 (15 pip range), ADR: 90 pips for GBPUSD.

Solution:Range = 15 pips (only 16.7% of ADR = high compression)\nRemaining ADR = 90 - 15 = 75 pips\n1 SD Up = 1.2550 + 0.0015 = 1.2565\n2 SD Up = 1.2550 + 0.0030 = 1.2580\n2.5 SD Up = 1.2550 + 0.00375 = 1.25875\nJudas Swing (bearish) = 1.2550 + 0.00075 = 1.25575\nBullish ADR Target = 1.2550 + 0.0075 = 1.2625\nExpect strong expansion from this tight compression

Result:15 pip range | 75 pips remaining | Strong expansion likely | ADR target: 1.2625

Frequently Asked Questions

What is the Asian session range and why is it important for ICT traders?

The Asian session range, often called the Asia Range, is the price range established during the Asian trading session, typically between 7 PM and midnight New York time. This range is critically important in ICT methodology because it establishes the initial consolidation zone that London and New York sessions will likely expand from. The Asian session is generally characterized by lower volatility and tighter price action, creating a compression zone. ICT teaches that smart money uses the Asian range as a reference for planning the daily range expansion. The highs and lows of this range serve as liquidity pools that institutional traders target during the London and New York killzones.

What is the ICT Judas Swing and how does it relate to the Asia Range?

The ICT Judas Swing is a deceptive price move that occurs at the London or New York open, designed to trap retail traders on the wrong side of the market before the true daily direction is revealed. It typically involves price sweeping one side of the Asian range (taking out stop losses) before reversing sharply in the intended direction. For example, on a bullish day, price may first sweep below the Asia low (the Judas Swing down), triggering sell stops and trapping shorts, before reversing aggressively higher. ICT teaches that this pattern occurs because institutional traders need liquidity from retail stop losses to fill their large orders. Identifying the Judas Swing relative to the Asia Range is a high-probability setup for experienced traders.

How do standard deviation projections from the Asia Range work?

Standard deviation projections use the Asia Range as a base unit to project potential price targets during subsequent trading sessions. A 1 standard deviation (1 SD) projection adds the full range size above the high and subtracts it below the low. A 1.5 SD adds 1.5 times the range, 2 SD adds 2 times, and so on. For example, if the Asia Range is 30 pips with a high at 1.0880, the 1 SD projection is 1.0910, the 1.5 SD is 1.0925, and the 2 SD is 1.0940. These projections serve as potential targets and reversal zones. ICT teaches that on low-volatility days, price may only reach 1 to 1.5 SD, while on high-volatility days or during news events, 2.5 SD or beyond is possible.

How does the Average Daily Range relate to Asia Range analysis?

The Average Daily Range (ADR) represents the typical daily pip movement for a currency pair and provides context for Asia Range expansion potential. If the ADR is 80 pips and the Asia Range is 30 pips, approximately 50 pips of range expansion remain for the London and New York sessions. This remaining range helps traders set realistic profit targets and determine whether the daily move is likely exhausted. ICT traders compare the current Asia Range size to the ADR to gauge whether the session is unusually tight (suggesting a larger expansion ahead) or unusually wide (suggesting limited remaining movement). A very narrow Asia Range relative to the ADR often precedes a significant directional move during London or New York.
