Good question George. The different time frame should be regarded as your investment time line.
If you're a day trader and want to scalp, you probably looking at a tick chart (each price movement is a tick) or a 1 minute chart. Here you're in and out with in typically 3 to 5 minutes.
If you're a daytrader you're probably looking at a 1, 3 or 5 minute chart. You in a play for 5 minutes to maybe 30 minutes to an hour.
If you're looking at a daily chart, you're most likely a swing trader (which is what I really am). These plays are 3 days to 3 weeks I like to say.
Weekly charts your now a position trader. You investment time line is measured in months, not days. Although I do often look at weekly charts to guage the trend of a stock and then play it on a swing trade.
Hope this helps.
Cheers!
PS: Intraday support has now moved up to $1.62 with an over sell of $1.60 on INT. I was again on the bid at $1.60 but didn't get filled this time. $1.66 seems to be resistance.
