referencing a previous bar to make a comparison

Just getting started here in trying to write a strategy and feeling a little limited with the possibilties but hopefully i just have not explored enough. i want to make the following comparison. 

I want to create a signal when the close of a 1 minute bar trades above the high of the previous 60 minute bar. I want this to be one of the rules. I have another rule as well.

Or even simpler, I want the high of the previous 60 minute bar to be my stop price to buy, meaning if it trades back up to that price, I want to buy at this price, assuming my other rule has been satisfied. 

Really confused as to how to do any of this?
