The user can select tye type of moving average ( , , or ).
For example, suppose you select a 200. Then you can see on the chart the 200 for the following timeframes: , M5, M15, M30, H1, H4, 1D and 1W, independently of the current timeframe.
Notice that plotting the 200 doesn't make sense in a H4 or , since it would overlap with the candles. It's not worth plotting it.
Thus, smaller timeframes moving averages are removed automatically from higher timeframes.
