Here is what I am currently using for UGAZ:DGAZ this fall/winter:
I have these charts lined up vertically like this on a PowerPoint page I open up each morning when I arrive at work. I plan my day accordingly if trades are needed. Most days I do nothing.
For a signal to buy, I am looking for: 1) The histogram crosses above zero line. 2) PMO black line crossing above red line. 3) Slope to be positive.
Following this, the histogram went positive on 13AUG. Slope being positive that day was conformation. Two days later on 15AUG, PMO crossed positive. I bought UGAZ at 13.50 on 15AUG.
This weekend it appears the Histogram is rolling over. A red flag. I will be watching for the slope to turn negative this coming week.
When the histogram nears or crosses below the zero line, the slope is negative, and the PMO black line has rolled over looking to cross under the red line, or actually crossed under the red line, I will sell UGAZ and begin watching the DGAZ chart using the same rules for buying in.
I am using this charting tool/strategy for other 3x ETF's too with good success.
BTW, I have stopped using the UGAZ:DGAZ comparison chart for trading decisions. PMO above zero line (I highlighted in yellow) means UGAZ has home field advantage.
