If you determine the trend, then follow it. Market trends come in a variety of terms - long-term, intermediate-term and short-term. The first thing you have to determine is what type of a trader are you, long term or day trader, that decision will determine which charts you should be using. For instance, if you're day trading, use the daily and intra-day charts, but always use the longer-range chart to determine the trend, and then use the shorter-term chart for timing. Make sure you trade in the direction of that trend and then buy on dips if the trend is up and sell on rallies if the trend is down.
