Hi,

I want to know whether it is possible to build a strategy which can work on two different data sets of one instrument. e.g. - Support for Instrument A, I get two data set files - One is daily data file and the other is Hourly data file.

Now I want to build a strategy mainly for Hourly chart, but I also want to do some action based on Daily Chart. e.g. If Daily Close is above daily 10 Days Moving Average, I want to do some action(buy or sell) for the Hourly Chart if the 10 Hourly Moving Avergae touches a bollinger band.

This is an example. I want to know whether this is possible with Wealth Lab?

Sure it's possible, quite common, and you don't even need both DataSets. Use just the hourly chart. See SetScaleDaily and SetScaleCompressed in the QuickRef for examples and descriptions.
