GBPJPY Possible short this week?

I think GJ might retest on its support this week.
Golden week started in Japan, so lots of holidays this week.
I am started forex 2 months ago, so I would love to see and learn how this will affect the volatility of GJ.

I am planning on fixing my trading schedule between London open and New York open.
only 1-2 trades per day.
Goal: 3%
risk: 1.5%
