I am looking to trade Equities and Equity Options based on the price of the underlying.
I need to have two data sets running in order to do that. The option should be on the top (data1) and the underlying equity should be on the bottom (data2).
How do I get both symbols to show up on the chart?
You have to go to "CHARTS" window and there to folder "BASIC CHARTS". AmiBroker is formula driven. So in order to see price or data in general you have to apply a formula. "CHARTS" window actually is the section where all your formulas (for charts and any other use cases) are located. It was named Charts window but not Formulas window or anything else because of many people (aka new users) having problems to find a link to applying charts.
Is there a free data source that can give me one minute bars?
By the way, when I change IBM from daily bars to 1 minute bars, the chart stays the same and I get no data at all on the AAPL symbol that I added, I don’t see any chart data there.
AmiBroker are not a data vendor.
You have to get the data either by importing it yourself (see ASCII import), or by using AmiQuote or by choosing a streaming source in File-Data base settings-Data source. For any missing vendors offering API access there is AmiBroker ADK (also see plug-ins forum section) to develop plugin for connecting to such additional cases.
Apparently you are applying the default data base that comes with AmiBroker setup. That one is an EOD sample offline database.
Anyway if you have a data source providing 1-min data then (see above) you have to go to File-Data base settings and set Base time interval to 1-minute.
