USD/JPY down to 108.4 and past according to my ARIMA ML model

https://pasteboard.co/JZxcfVD.pngI have used the presented leading drivers from the book "The art of currency trading" by Brent Donnelly to build an ARIMA machine learning model, using the us 2y 5y and 10y bond interest rates as well as gold, spx and nikkei225 to build the model, i had entered at 108.848 and set my take profit for 108.4, went to sleep had i been awake i would have taken profit when the market nearly touched this mark, the median line for the regression model is at 108.25 area, according to price action i believe this looks like a retest before going back down.

picture of my model in the link above! as you can see the market as respected this regression predictor fairly well in the past, I am also confident due to the mac d indicator indicating a sell on the 4 hour time frame.

I actually didn't set a stop loss for this trade as I believe it will go to 108.4 much before it hits 111

Fundamental news has bears looking at the 107 area from the article i read on fx street from the us bond market being weaker, which is what this model is partly based on.
