Trading without Indicators is not rocket science and far less complicated as one might think. Some simple trendlines for guidance and breaks and some S/D levels to watch is all there is. Just need to acquire some confidence and learn to trust your approach.
One also might want to use the MT4 channel indicator i.e it draws a channel when you draw a trendline. Sometimes it's good to visualize the move.
Well, that's the way I trade day in day out. It works on all TFs.
I only trade the US 30, nothing else. It's more than enough to make money.

Nice move to the downside today when Europe opened.......
Any Indicators needed? Nope! Price action right off the Trendline.
