Very interesting data on EURUSD:

[ Taken from @edgeful ]
When the Asian range ends, if the first 15-minute candle that closes outside the range does so on the upside, the day ends green 73% of the time.
And if the first 15-minute candle that closes outside does so on the downside, the day ends red 76% of the time.
Every time the first m15 candle breaks and closes outside, historically the daily close tends to follow that direction.
Range schedule:
19:00h to 04:00h.
After 04:00h, I simply wait for the first m15 close OUTSIDE the range.
If it closes on the upside, I prioritize longs.
If it closes on the downside, I prioritize shorts.
I believe there is no simpler way to identify the daily BIAS.
