Entry is taken up on tomorrow's candle, at last month's R3 level. Keep an eye out on price action in regards to the (price must break this in order to push lower (and possibly retest last month's R3 before pushing lower).
Aggressive trade would be to enter at market with stops as mentioned... but it's only a difference of a few pips.
I suspect this trade will keep running for the rest of this week, or perhaps well into next week's FOMC meeting. Do make sure to book profits or BE at the very least ahead of the minutes if the target isn't reached.
