in my post I wrote:
"If one use the "Happy Hours", you can see that statistically, regardless of GMT, the bar ranges (volatility) for this pair increase between 06:00 - 10:00, continue to increase until 17:00, and then decrease."
For me this means that you can take the range of 2-3 hours (4 to 6, or 5 to 7 etc.) and you trade the breakout of the range until about 5 p.m. because then there is a higher volatility.
The hour ranges are determined statistically and there are no problems with the GMT offset which my broker has just increased from 2 to 3 this week.
In #Post 54 you can also see that for a trading system e.g. on M5, it would be interesting to trade the increasing volatility from 7 to 10 and from 14 to 17.
Such precise information would be very important, and as far as I know, nobody has taken this indicator seriously ...
