This indicator allows you to view a moving average (EMA or SMA) of your choosing on other time frames than what you are currently on.
The reason I wanted to develop this was for use as a filter. Let's say you wanted to make sure the daily time frame was trading above a certain moving average so you could be sure you were playing with the trend. But you wanted to make your entries and exits on a smaller time frame. This Multi-Timeframe Moving Average indicator can then be used to keep an eye on that daily moving average while looking at the shorter term time frames on the same chart.
