No worries, thanks for the questions!

The lookback period (5 / 10 day), doesn't particularly matter to me since that is just showing how much data is actually on the chart.  Personally, I like a good amount of data on the chart so that I don't get caught up in the candle-to-candle battle for dominance.  The moving averages are calculated based on the data (hourly / daily / 15-minute), so how much data you show on the chart is not terribly important.  

I prefer the 1 hour chart because it allows me to have a trade for 2-3 days.  It suits my risk appetite and my desire to participate in the trend.  I consider this intermediate term trading while anything shorter I call short-term trading.

It really depends on what you are looking for.  If you want to trade once every few weeks, then I'd use the daily chart to make your trading decisions.
