London Open Playbook Generator
Asia is done and London is about to open. Enter the Asia session high and low and the 20-day ADR, and the generator writes the London plan: whether the Asia edges are fades or launch pads, the entry, stop and targets for each play, the ADR-projected extremes, and what flips the bias. The rule of thumb is old FX desk lore: the Asia range and the ADR share one budget. A narrow Asia range leaves London the room to run, a wide one has already spent it. The thresholds here are 25% and 45% of ADR; that's this tool's convention, not a law. Session hours use each city's own clock, so daylight saving is handled.
Sets how distances are read out. Asia is 09:00 to 18:00 Tokyo time, 00:00 to 09:00 UTC, so the range is the high and low of those 9 hours.

Enter the Asia high and low and the ADR, then hit Write. Or load an example to see a coiled day next to a wide one.
How it decides. Ratio = Asia range / 20-day ADR. Under 25%: breakout bias. Asia coiled, London has 75% or more of the day's usual range left to spend, so the Asia edges are triggers, not walls. 25% to 45%: 2-way. The first London push into an Asia edge is a fade only with a rejection bar behind it; a 15-minute close outside the range flips it to the breakout play. 45% or more: fade bias. Asia already spent half the ADR, so London pushes into the Asia edges are fades back to the Asia midpoint. Fade stops sit 20% of the Asia range past the edge. Breakout entries are the edge itself, stops at the Asia midpoint, T1 one Asia range beyond the edge, T2 the ADR projection (Asia low + ADR for the upside, Asia high minus ADR for the downside). The ADR projections are the day's usual reach and the last place to hold a runner. Sessions on the clock: Tokyo 09:00 to 18:00, London 08:00 to 17:00, New York 08:00 to 17:00, each in its own local time. Keyboard: Enter writes, 1 to 3 load the examples.
Educational tool only, not financial advice. The ADR is an average. A news day spends it twice, and a holiday never touches it. Check the calendar before you trust the budget.
