How do I get the highest high?

[coverman]

Does anyone know how to get the value of the highest high from the 5 last candles. And the lowest low.
I would like to get the value from the highest high of the 5 last candles on a 1H chart to set my next bid.
I want to make a BUY 5 pips above the highest high from the last 5 hours and a SELL based on the lowest low.

But not sure where to get that number from. What block should be used and how?
What is the best solution?
