If you are in our community you would have engaged the Bullish Crab Pattern on the USDJPY trade you would have gained 37pips and have your stop-loss shifted to entry without working the market might go against you.
If you have not, that's not the end of the world, since the trendline(blue line) is not broken, that could be an opportunity for you to long. However, I won't do that.
I would rather wait for it to retrace to its previous low point, or even better a bullish bat pattern form at 104.61.
