DislikedInteresting data on GBPUSD for the last 30 trading days:
MM didn't change after 12:00 GMT (NY OPEN) until end of day 73% of the times.
ADR within trading range of 40% - 60% of ADR happened 43.3% of the times before 12:00 GMT.
Therefore, my premature conclusion on such small data collection is that there should be an optimal time window (lets say 9:30 - 12:00 GMT) in which we have a higher probability of getting entries within range and that will have less chances of changing the MM until the end of the trading day at the same time.
MM didn't change after 12:00 GMT (NY OPEN) until end of day 57% of the times.
ADR within trading range of 40% - 60% of ADR happened 30% of the times before 12:00 GMT.
MM changed 62% of the times(after 12:00 GMT) when ADR was below 51% before 12:00 pm GMT.
* on 60% of the times, ADR was above 60% before this particular time was reached.
My premature conclusion on such small data sample for EURUSD is that there is also a time window between London open and 12:00 GMT for trading this template along with ADR not being lower than 51%. However, timing wasn't so significant as it was for GBPUSD in the last 30 trading days.
