As the volatility changes and the volume drops, I change my bar size to see the order flow better. NOTHING else changes. I'm monitoring the trend of the one chart and trading the pullbacks. I use the CCIs and the EMAs to track these events.
Today's DAX open created an uptrend. The overnight ES showed that this would occur. The reaction of AAPL to its earnings report was mostly responsible as the market could have gone either way after yesterday's trade.
I dropped my Renko to 3 with the wick so I could see the pullbacks better. I had targets from my Fav Fibs. The results are in the chart below.
The divergence indicated by the Orange lines was a pause in the move. Trend remained intact but alerted me to look for a solid re-entry which came later.
