Every *consistent* trader/investor is unique. Personally, I believe is important to look at more than 1 time frame and I mostly use tick charts.
Trading is about taking advantage of opportunites. The smaller your time frame the greater the number of opportunities to trade. Each time frame produces trades with a specific reward/risk profile. You have to study the time frames to know what this reward to risk profile is. You also must know what your expectancy is per time frame. (Average win * % Win) - (Average Loss * % Loss).
