# TimeArray indexing

I’m playing around with the MarketData package as a way to learn Julia. Now I’ve run into a simple question: How do I access the actual number inside a TimeArray?

I’m following the MarketData example to get the daily closing price of Apple’s stock:

``````using MarketData, TimeSeries
AAPL = yahoo(:AAPL)
``````

That works great. I can see a full time series of daily closing prices in a column called `AdjClose`. Now I would like to plot the price history as a percentage of the most recent closing price. The mathematical formula for that is easy, and I think it should be possible to calculate it like this:

``````price_percent = 100 .* AAPL[:AdjClose] ./ AAPL[:AdjClose][end]
``````

That is, the full time series, divided by the most recent closing price. The problem is, the most recent closing price, which I attempt to acces by `AAPL[:AdjClose][end]`, is not a scalar, so I can divide the full time series by it:

My question is how do I access that `165.29` value so I can divide the entire time series by it?

You could use a field getter function

``````price_percent = 100 .* AAPL[:AdjClose] ./ values(AAPL[:AdjClose])[end]
``````

Brilliant, that worked perfectly. Thanks @goerch!
