Show a Simple Moving Average from a different timeframe to your chart.
In the example above I am using a 1hr chart, with 3 moving averages on it - The 10 period MA from the 3D timeframe, the 50 period MA from the 1D timeframe and the 100 period from the 4hr timeframe.
It really lets you keep an eye on key moving averages from multiple timeframes, on a single chart.
