Right now you have a very healthy balance to trade and you have opened buy orders in USDJPY. I completely agree with your entry points of USDJPY as the 104.10-104.15 area was the 61.8 FIBO support level and also very strong support level horizontally. Personally, I was expecting the pair to make an immediate bullish reversal from this support level but it actually breaks below. Right Now The pair is fighting to break below the 103.75 support level and if it breaks as well then the buy orders should need to close.
Fundamentally the good vaccine news should strengthen the USD but, I think the ongoing dilemma of presidential power shifting and the new rise of covid-19 in the USA is devaluing the USD. But I am not expecting a very big fall from this point as the successful vaccine may be available very soon and that will make the USD strong again.
So I would suggest you keep the trades running with a stop loss of around 103.65 and abort it goes any further. Also, it's better to trade with lesser lot sizes as the unscheduled news can cause big damages. Wishing you best of luck with your trading.
