I agree @yokoyi.
The best time to trade for Nigerian forex traders is the opening hours of the London session, from the start of Frankfurt open at 8AM Nigeria time (which is 7AM UK time).
From 8AM-11AM is the best time based on what I trade, but it also depends on your system, and the instrument.
For trading EUR & GBP currency pairs, this time is the most active when you can catch some momentum.
The Frankfurt & London, these 2 hours will have some directional movement, on most days. Both could be opposite as well, it happens around half the days. It is possible to build a system with edge around trading during these 2-3 hours only.
If you are wrong, then you just accept your lose & move on to the next day.
In general, I want to add that avoid being infront of the screen for too long, it mostly leads to bad outcomes & lower overall monthly P&L.
Why am I saying the above?
To the original question, It is okay to know what time does Sunday open, but I don't think it really helps you, not if you have a system or trading setup built around trading the Sunday open.
So, if you are sitting during the Sunday open, watching the charts, tracking the opening, then I don't think you can really do well in the long term. I'll add, unless, you actually have a system around it, and have a reason to.
