Always keep things simple.
As you can see here with the 50 range bar chart for e-mini futures, when the 9 day EMA (green) crosses above the 20 day EMA(red), price direction is clearly defined.
Using range bars gets rid of a lot of the noise associated with time-based charts, and keeps other time frames from invalidating your ideas making you miss out on good trading opportunities.
As of now, if the 9 day can cross the 20 and hold we will see a good opportunity to open a long position.
