Hey Grantyboy,
i've seen those trades before...in my own blotter! I've made almost every mistake in the book..so here's what i did different yesterday as i too was in GA. I saw the divergence on the 1H chart since the 4H pricing was still bullish. We were bouncing from a logical support area/round number 1.8600. I waited for the sub-hourly charts to print higher lows and in particular we got a 15min 1-2-3 formation, where i inserted an entry order. My stop was below the day's low. I bailed up at the recent highs in the 8730s.
To me, you were pushing the ADR letter a little too much up there, especially close to a stiff resistance. A little better would have been to wait for the pullback to the overhight high in the 8670s, targeting another push towards the stiff resistance. You would have also had indicator support to engage there.
Also, by managing on a 5min chart (another thing i've tried) chances are that you will over manage your trade. You will get out because the 5 min trending action is over...but it's just an intraday spoof for some reason or another...the main levels that need to be compromised in order to seriously doubt your planning are bigger: 1H evident swing points/consolidation areas and current day high/lows, asian high/lows...etc... prices that have a meaning to them for more than intraday players.
Hope this helps!
