Asia Sell / US Buy + Regime Flip (Crypto Sessions)Indicator Description: Asia Sell / US Buy + Regime Flip (Crypto Sessions)
Purpose
This indicator breaks the crypto trading day into Asia and US sessions, measures each sessionโs directional contribution, and highlights when leadership shifts (a โregime flipโ) from one session to the other โ e.g., โAsia sells, US buys,โ and when that pattern changes.
โธป
Sessions (default, in UTC)
โข Asia session: 00:00โ08:00 UTC
โข US session: 13:30โ20:00 UTC
(You can adjust both sessions in the settings.)
โธป
What the indicator calculates
For each session, it computes one of two selectable metrics:
1. Return (Session Return)
Return = \frac{Close_{end}}{Open_{start}} - 1
โข Positive = the session pushed price up (net buying pressure)
โข Negative = the session pushed price down (net selling pressure)
2. Pressure (Volume-Signed Proxy)
A rough โdelta-likeโ proxy accumulated during the session:
โข Candle closes up โ +volume
โข Candle closes down โ โvolume
This is not true bid/ask delta, but it often approximates directional effort by volume.
โธป
Core signal: US Advantage vs Asia
The main line is the spread:
Edge = US\_metric - Asia\_metric
Interpretation:
โข Edge > 0 โ US session dominates Asia (often โUS buying / absorbingโ)
โข Edge < 0 โ Asia session dominates US (often โAsia selling / pushing downโ)
A smoothed Edge MA is plotted to visualize the underlying regime more clearly.
โธป
Regime Flip (Cycle Change)
The indicator marks leadership switches:
โข Cycle flip: US > Asia when Edge crosses above 0 (from negative to positive)
โข Cycle flip: Asia > US when Edge crosses below 0 (from positive to negative)
Optional noise control:
โข Min edge filter (x ATR) filters out weak flips during low-quality chop by requiring Edge magnitude to be meaningful relative to ATR.
โธป
What you see on the chart
In the indicator pane:
โข Asia metric (Return or Pressure)
โข US metric (Return or Pressure)
โข US โ Asia (Edge) โ the main dominance line
โข Edge MA โ smoothed regime line
โข Flip labels โ printed on regime changes (optional)
A top-right dashboard table shows the latest Asia/US metrics, Edge, and the current regime (US dominant / Asia dominant).
โธป
Recommended use
โข Best timeframes: 15mโ1h (too small = noisy)
โข Start with Mode = Return for clean interpretation
โข Use Pressure when you want a volume-sensitive โeffortโ proxy
โข Increase Min edge filter (x ATR) (e.g., 0.5โ1.0) for fewer, stronger flips
