Asia Session ORB: Range Trading, Breakouts, and Metals Context

How to use Asia session ORB levels for metals, yen-sensitive markets, and overnight index tone.

OR high (00:00–00:15 GMT) OR low Confirmed M1 close 15-min range
Asia session: the range is fixed at 00:15 GMT; a breakout is a closed M1 bar beyond it, on 1.5× volume.

The window, by the clock

Asia runs 00:00–09:00 GMT. The opening range is the high and low of the first 15 minutes of M1 bars — 00:00 to 00:15 GMT — fixed the instant the fifteenth bar closes. It is never redrawn, never eyeballed, never adjusted to "the real move". Same box definition every day. All session math runs in GMT and is converted to broker server time internally, so a DST shift on your platform does not move the range.

London07:0015:0007:00–07:15
New York13:3020:0013:30–13:45

Two overlaps matter. The Asia range forms while Sydney (open since 22:00 GMT) is still running, so Asia inherits two hours of existing positioning rather than a cold book. And Asia's last two hours, 07:00–09:00 GMT, run under the London open — which is where most Asia trades get their final verdict.

Who shows up at 00:00 GMT

00:00 GMT is 09:00 in Tokyo: the Japanese cash equity open. That is the order burst the Asia opening range captures — overnight positioning in yen pairs, Japanese equities, and gold colliding with fresh flow at a fixed, known time. Mainland China and Hong Kong are not in yet. Shanghai and Hong Kong cash trading starts around 01:30 GMT, roughly 75 minutes after the Asia box is already locked.

Trade that fact, don't fight it. A confirmed Asia breakout at 00:40 GMT often gets its second leg — or its failure — when Chinese flow arrives at 01:30. Don't declare the trade finished before that window has voted. And a breakout that confirms between 01:30 and 02:00 is being confirmed by the deepest liquidity the session will see.

For XAUUSD, Asia is a live session: Asian physical and paper gold demand is real, and gold regularly prints a directional leg between 00:00 and 04:00 GMT. US100 is a different animal overnight — index futures trade the electronic session with the underlying US cash market closed, so tick volume runs at a fraction of New York. That is precisely the environment the volume filter was built for.

Same engine, calibrated expectations

The Asia session runs the identical mechanical engine as Sydney, London, and New York. Nothing about the trigger changes; only what you expect from it does.

  • Range: high/low of 00:00–00:15 GMT on M1. Fixed at 00:15. Final.
  • Trigger: a CLOSED M1 bar whose close — not its wick — is above the OR high (long) or below the OR low (short). A wick poking through the level is nothing. Evaluation happens once per closed bar.
  • Volume filter: the breakout bar's tick volume must be ≥ 1.5× the average of the 20 bars immediately before it. No volume confirmation, no trade. In a thin overnight book this filter does most of the work — it demands real participation before the signal exists.
  • One shot per side: at most one long and one short per session per day. Once a side fires, it latches.
  • Stop: the opposite side of the opening range. That distance from the confirming close is 1R.
  • Targets: Target 1 at entry ± 1R, Target 2 at entry ± 2R. Defined before the trade exists.

The flow layer — expected move, gamma walls, smart-money strikes from institutional option flow — is confluence, never trigger. It grades a signal, caps a target, or turns a marginal setup into a skip. An Asia US100 breakout aimed straight into a mapped wall from the morning report is a skip. It does not create entries and it does not override the volume filter.

Worked example: XAUUSD long, Asia

00:00–00:15 GMT prints OR high 3342.60, OR low 3338.40 — a 4.20-point box. At 00:41 GMT an M1 bar closes at 3343.90 on 2.3× the prior 20-bar average tick volume. Close beyond the level: pass. Volume: pass. The long fires once:

FieldValueHow it's computed
Entry3343.90Close of the confirming M1 bar
Stop3338.40OR low — opposite side of the range
1R5.50 points|3343.90 − 3338.40|
Target 13349.40Entry + 1R
Target 23354.90Entry + 2R
Volume2.3× averageBreakout bar vs prior 20-bar mean

Those six numbers are the alert embed, verbatim. Invalidation is the OR low: a later confirmed close below 3338.40 on qualifying volume fires the short side once — and the long stop sits at that same level by construction. After both sides have fired, the session is done.

Counter-example, US100 the same night: OR high 23,110, OR low 23,078 (32 points). At 00:52 an M1 bar closes at 23,116 — six points clear — but on 1.2× average volume. No signal. That is not the engine being slow; that is the engine refusing a rumor. Overnight index breaks without volume routinely snap straight back into the box.

Typical overnight behavior: XAUUSD vs US100

XAUUSDUS100
ParticipationGenuine: Tokyo open, yen-driven flow, Asian gold demandElectronic session only, no cash open, thin book
Volume filterPasses more often — the 00:00 burst is real order flowFails more often; many Asia breaks die on the 1.5× test
Follow-throughLegs to 1R–2R happen; extension beyond 2R is rarer than London/NYModest; overnight index pushes often rotate back toward the range into Europe
Primary useTrade the confirmed break; respect Target 1Reference frame: the Asia high/low define the overnight box London opens against

The last row is the real lesson. On US100, an Asia session that never fires a signal is not wasted — the fixed 00:00–00:15 box plus the session high/low become the overnight map London and New York trade against. Same rules everywhere; expectations calibrated per session.

How Asia frames the London open

London opens at 07:00 GMT with its own fixed 07:00–07:15 range and its own independent signals, while Asia still has two hours on the clock. By 07:00 the Asia box is seven hours old and London's first real liquidity wave votes on it. Three repeatable reads:

  • Asia break held, London extends. Price sits beyond the Asia range at 07:00 and London pushes the same way. The Asia OR levels now serve as the pullback floor or ceiling for the London leg.
  • London reclaims the Asia range. Price closes back inside the Asia box after 07:00. The overnight move was inventory adjustment, not conviction. If you are still carrying an Asia breakout past Target 1, this is the exit read — and the levels feed marks the session status accordingly.
  • Asia never broke. A tight, unbroken Asia box into 07:00 is stored energy, not failure. A 30-point Asia range on US100 going into the London open is compression — expect London's own opening range to resolve it.

Asia does not hand London a trade. It hands London a map: two fixed prices the whole overnight market has already fought over.

What the bot posts for Asia

At 00:00 GMT the Discord bot fires the Asia session-open ping. When the 00:15 range completes, it posts the Daily ORB Levels embed per instrument — OR high, OR low, range in points — for XAUUSD, XAGUSD, and US100. Confirmed breakouts (entry, stop, 1R, 2R, volume ratio) hit the Premium channel as they fire. The EA is signals-only: it places no trades and manages nothing. Every signal, losers included, is logged openly in the results channel. No hype, no guarantees, just data. Education, not financial advice.
