1. Based on the last 16yrs of daily close data (since 01 / 01 /2000 to date) USDJPY has a cumulative probability of a =>7th day lower at 0.6%, hence there is a implied 99.4% chance of reversal on the daily.
2. Technically there is also some nice structure about the 103 level.
1. Sell USDJPY at market in 1xlot, and add 2x on each daily close higher from here. Start in VERY small lots to reduce risk and ensure you can add on adverse moves lower (it could be several days). TP is the next/ First daily close higher.
