EUR/USD huge price spike at 23:00?

Hi guys,

I understand there is always some big spread everyday around 23:00, it is fine.
but today’s fluctuation is just a bit too much or not?
I have attached a screenshot (which is charted on buy price). You can see the price jump around 23:00 eats up almost entire day’s change. The same happens to the sell price.
Is this really normal? I
If yes, can anyone pls advise where I should put my stop loss?
