I personally always look at weekly charts, to get an overall view of where the stock has been, and where it is now.
So I look at weekly charts a lot (even though most of my trades are monitored on the daily chart, once I have made an entry).
I also look at weekly bars of stocks I am interested in, or hold, each weekend.
When looking at the weekly charts, I also want to work out the price action in my own head, and have a reasonable understanding of the what the price action is saying about itself. (and if I can't work out the weekly, I will have a look at the monthly in an effort to understand the chart).
For me, the chart needs to be 'Understandable'....it needs to 'make sense' to me (even if it is likely to be just the retailers trading amongst themselves, with little or no professional trading). If I can't understand the chart, it is unlikely I will buy the stock.
Do you remember the bar by bar I have been doing.....the price action always made sense when it was being supported.......and when the price action became confusing it turned out to be under distribution (and the inverse is also true - when under accumulation).......
I like stocks that have broken out, and are in an uptrend, and are being supported.......during the mark up phase......before any distribution.
