Asian Range & London Breakout

The Asian Range is the high-to-low price range formed during the Asia session window (commonly approximated as 19:00–00:00 New York local time). In ICT-style intraday trading, the Asian Range often acts as a liquidity reference: London may sweep above/below the range to run stops, then either reverse back through the range (reversion) or continue with displacement away from the range (breakout/expansion). This is a session-context + liquidity model, not a standalone candle pattern.

Definition

Asian Range is the session-defined high/low formed during the Asia window. Traders use the Asian High/Low as objective liquidity levels. A typical play is a London sweep of one side of the Asian Range followed by displacement and a retracement entry toward daily objectives. The concept is about time + liquidity behavior: range formation (Asia) → liquidity raid / breakout attempt (London) → delivery (toward targets).

Why It Matters

Asian High/Low provides a repeatable set of intraday reference levels. Many high-probability intraday moves begin with a liquidity sweep of the Asian Range during London, followed by displacement that reveals the day’s intent. Using the range reduces randomness: you know where liquidity likely rests, where a raid is obvious, and where a breakout is meaningful (vs. noise).

How to Identify

  1. Convert all candle timestamps to New York local time using IANA timezone 'America/New_York' (ET) to avoid DST issues.
  2. Define the Asia range window (default: 19:00–00:00 ET; crosses midnight).
  3. Compute Asian Range High = highest high inside the window; Asian Range Low = lowest low inside the window; Asian Midpoint = (High + Low) / 2.
  4. During London window (default: 02:00–05:00 ET), watch for a raid: price trades above Asian High or below Asian Low and then returns back inside the range.
  5. Confirm intent with displacement: a strong impulse candle (body size threshold) that closes away from the range and breaks short-term structure (MSS/CHoCH).
  6. Treat the Asian Range boundaries as liquidity targets and reaction zones; only trade when a model trigger occurs (sweep/raid + displacement + retrace into a PD array).

How to Trade

  1. Mark PDH/PDL, ONH/ONL, and key HTF levels; define a daily bias (or at least a directional hypothesis).
  2. Box the Asian Range (High/Low) and midpoint; annotate Asian High and Asian Low as liquidity pools.
  3. In London (02:00–05:00 ET), wait for a sweep of Asian High/Low AND a displacement candle closing away from the range.
  4. Enter on retracement into a PD array (e.g., FVG/OB) aligned with premium/discount relative to the Asian Range midpoint and HTF bias.
  5. First target is often the opposite side of the Asian Range; further targets include PDH/PDL, ONH/ONL, or next external liquidity.
  6. If price re-enters and accepts deep into the Asian Range after displacement (or breaks the opposite boundary), reduce confidence or invalidate the setup depending on direction.

Common Confusions

Confusing 'Asian Range' with the entire Asian trading session

IF you are calculating a specific high/low box for a defined window (e.g., 19:00–00:00 ET) THEN you are using Asian Range. IF you are referring to broader market participation hours without a defined high/low box THEN you are referring to the Asian session.

Confusing a liquidity sweep with a true breakout

IF price trades beyond Asian High/Low but closes back inside the range quickly AND displacement_strong != true THEN treat it as a sweep/raid (not breakout). IF price closes beyond Asian High/Low with displacement_strong = true THEN breakout intent is more likely.

Assuming London always breaks the Asian Range in the direction of the day

IF HTF bias is unclear OR price repeatedly re-enters the range THEN probability drops. IF sweep + displacement aligns with HTF bias and daily liquidity objectives THEN probability increases.

Implementing the Asia window incorrectly because it crosses midnight

IF window crosses midnight THEN use (t >= start) OR (t < end). IF window does not cross midnight THEN use (t >= start) AND (t < end).
