see which TP you put. if you're aiming for TP at the previous high, cut loss at below 2, then ur risk & reward ratio is just nice & acceptable. Or if you can hold through the volatility whenever pullbacks happen in the coming time, you may just enter with the amount you're comfortable with. DYODD, look back at my technical analysis in the comments below.

Maijiushi bro, if it really retraces back to 1.8 before hitting the previous high & higher high, I advise you not to enter again. better to study the chart, from now retrace back to 1.8 that's not called retrace, you might as well cut loss or don't enter.
