<<why wouldn't you use the trend in the daily chart to increase your trade size when price moves in that direction in the lower timeframe charts (i.e., the one you trade off)? >>
I guess what I was trying to say but didn't come out and say was --- I have a slight bias towards fading any trend that develops on a daily chart. I don't believe in sustainable trends on the daily chart -- I believe in choppy daily action...
Now, don't get me wrong -- I DO believe in trends on intraday charts so I will take full size for an intraday trade even if it lines up with a daily trend --- having said that I want to fade the daily trend. So effectively, the daily just has no bearing on my trading.
<<how do the weekly charts affect your trade decisions? >>
they don't currently. But when stepping out to this timeframe -- the indicators seem to want to speak to me. always playing around -- check this one out (buy weekly macd histogram upturn that occurs during traditional seasonal strength for second half rally --- sell Jan 31st):
