Visualize an indicator and guess its purpose - I

Now you will visualize these indicators to understand why you might want to use the indicator and what it may represent. Recall that a trend indicator attempts to predict whether a price will continue in its current direction, whereas a reversion indicator attempts to predict whether an increasing price will soon decrease, or the opposite.

In this exercise, you will revisit the 200-day SMA. As a refresher, this indicator attempts to smooth out prices, but comes with a tradeoff - a lag. You will plot the prices of SPY and plot a 200-day SMA on top of the price series. Using this information, you will determine if it is a trend indicator or reversion indicator.

The quantmod and TTR packages and price series SPY have been loaded into your workspace.
