I think it doesn't need a lot of work! I did some work with envelopes and they gave outstanding results. Can be used on any timeframe and gives good trend direction as well as entry points. It gives you an instant picture of how volatile a given market is at any given moment. I have included settings for both when market is ranging via the smaller envelopes settings as well as when the market is expanding and higher envelopes settings are needed to measure the targets.
