Expert Advisor monitoring multiple time frames

[johnmcgiles]

I'm new to metatrader/mql 5 and trying to build a basic expert advisor that trades the M5, but must monitor the daily high and low and also the H1 candlestick chart.  The only way I can determine to monitor multiple timeframes/charts at once is by building an indicator for each timeframe other than the chart my EA is attached to.  Is this the only way? Or can multiple timeframes/charts be monitored without building a separate indicator for each?  Any help with this would be appreciated.

At CodeBase there are examples of multi-currency indicators.

I believe when you call the indicator; that you can specify a time frame.

you write them in ONE indicator or expert, I think it is easy for you to create a expert
