Trading around central-bank FX intervention
Choose central-bank base-currency buying/selling and follow/fade, then enter the FX move, notional and costs.
Central-bank FX intervention may smooth or reverse currency moves, but markets can anticipate it and direction, credibility and duration vary. Some research links technical-rule returns to intervention periods; this does not mean every intervention is tradable. This simulation maps a manually entered intervention direction to a long or short position and applies a hypothetical FX move.
No official intervention flows, FX history, policy events or execution costs are loaded; this is not a live signal.

The mechanics · payoff and exposure
Position=InterventionSign\times(1_{follow}-1_{fade}),\quad P\&L=Position\times FXMove\times Notional-C
The pair follows base/quote convention; the FX move is entered as a base-currency return.

| Conservative version | Higher cost/loss | Stress higher costs, larger losses or lower liquidity. | May lower scenario returns. |
| Validation version | Data review | Test model inputs with consistent contracts and timestamps. | Needs licensed, representative data. |
