On USDJPY, we should being Selling from last Friday till we see a change in Colour to Blue. We are really waiting for a bullish blue Average price bar to close above the low of the last bearish candle ( turns blue ).

Monthly is Bullish +
Weekly is Bullish +
I need Daily to become Bullish +
H4 Break to the upside A
