title: How to plot highest price of higher timeframe and view it on lower timeframe charts
body: <p>I'd like to see the highest price of last 5 days on 4h chart and maybe other lower timeframe charts. The function that I found in coding reference: <code>highest(source, length)</code> seems not taking interval as a parameter. I came from mt4 which having this feature. So how do we do this in pine script?</p>
