It's very easy, I read the daily and weekly charts the same way, but, the difference is that the weekly chart gives me the whole picture, on the SAPX case, the daily chart points to a short run on the short term, possibly to .67, but, the weekly chart points to a much bigger run, to 1.00 - 1.50, on a spike or on a run to .67, then a pullback to .48, to give chance to the RSI on the daily chart pull back to 50, and, then a run to 1.00 - 1.50.
So the weekly chart shows that a run to 1.00 - 1.50 is possible, when the daily shows me that only .67 is possible, I will play the weekly chart, it means I will wait for a spike(1 - 3 days), or a run(1 - 2 weeks), and, sell above 1.00.
