USD/JPY Time To Long?

Good Evening,

Attempting to identify a reversal point via USD/JPY.
Three possible scenarios so far:
1. Price rebounds off of 800EMA (illustrated above)
2. Price fails to rebound off of 800EMA and Retest trend line structure.
3. Bullish momentum continues and passes trend-line.

Please, if you have any ideas to contribute please comment them below.

Thanks,
Trade Wisely
