A new pillar piece on CrossVol Research, in 11 languages.
Almost every retail FX education product stops at three signals: order flow, support/resistance, and economic calendar. None of them tell you where dealer positioning sits in option-space. Yet on EURUSD, USDJPY, GBPUSD, AUDUSD and USDCNH, the option market is where the regime is priced first — the cash-FX move that hits the chart is the last leg of a sequence that started in the options book several sessions earlier.
The asset is institutional by gravity. Retail FX brokers earn on the cash-FX spread, not on options, and have no commercial incentive to point their clients toward the part of the market that would let them stop being directional gamblers. The result is a public information vacuum: thousands of YouTube tutorials on Fibonacci-on-EURUSD and almost none on how dealers are gamma-positioned on EURUSD into the next ECB meeting.
The CrossVol Terminal closes that vacuum. The same four lenses that read SPX read EURUSD, USDJPY, GBPUSD, AUDUSD, USDCNH, USDCAD and USDMXN.
The four lenses, applied to FX:
GEX flip zones and walls — where dealer hedging is most concentrated. Spot punching through a wall is a regime change, not a noise event.
Vega map — the silent carry-trade detonator. The August 2024 yen carry unwind had the vega asymmetry signal flagged 2 weeks before the move.
25-delta risk reversal — the single best cross-asset translator of regime change. A 6σ shift in the EURUSD 25Δ RR preceded the 8 April 2025 tariff sell-off by five sessions.
Term structure & physical anchors — the slowest signal, the most reliable.
Three dated case studies inside the article:
5 August 2024 — USDJPY yen carry unwind
8 April 2025 — EURUSD post-tariff sell-off
8 October 2024 — GBPUSD and the gilt echo
The framework is the FX-spot extension of the system in Beyond Gamma Exposure (Amazon Kindle, May 2026).
