The overall trend was (is) pretty UP, as we can see in daily charts, now where to buy..
Low of course.
Market reached the lows of the previous week, and as soon as it did get there, it has been bought heavily again!
On the 4h chart we can see it more clearly, a down move straight to the lows, with some exhaustion bars just at the bottom (and one before reach the previous week lows), and then 16 hours (four 4h bars) of choppy market (down momentum dried up).
Edit:
To be clear, exhaustion bars and momentum dry up are just confirmations, the point where we want to buy or sell is below/above previous relevant lows/highs, only after price reach such levels we watch for confirmations, and enter our trades.
