Asia Range Calculator
Calculate the Asian session range high and low for ICT Judas Swing and CBDR strategies. Enter values for instant results with step-by-step formulas.
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.
Can the Asia Range be used for indices and commodities or only forex?
The Asia Range concept can be applied to any market that trades during Asian hours, including stock indices like the Nikkei 225 and Hang Seng, commodities like gold and oil, and even cryptocurrency markets. However, the concept works best in markets with distinct session-based volatility profiles. Forex pairs, particularly those involving the US Dollar, Euro, and British Pound, show the clearest session-based patterns because liquidity shifts dramatically between Asian, London, and New York hours. Gold (XAUUSD) also responds well to Asia Range analysis because it trades actively across all sessions. For US stock indices, the overnight session range serves a similar function to the forex Asia Range, establishing the consolidation zone before the cash market opens.
What is the difference between Asia Range and London Range in ICT methodology?
The Asia Range and London Range serve different roles in ICT methodology. The Asia Range represents the consolidation or accumulation phase, characterized by low volatility and tight price action. It sets the stage for the day. The London Range, formed during the London session (2-5 AM NY time), represents the initial expansion phase where smart money begins its daily directional move. The London session often sweeps one side of the Asia Range before establishing direction. ICT teaches that the London session creates approximately 70% of the daily range, making it the most important session for establishing bias. Traders use the Asia Range for context and the London session for trade execution, looking for the Judas Swing followed by the true directional expansion.
