This supertrend does not use a multiple of current average true range (ATR) as the distance to median prices. Instead, the distance of the supertrend line to median prices is only a fraction of the current price (close * factor).
In sideward phases, when average prices do not change, this supertrend will stay constant. The “normal” supertrend (using ATR) will reduce its distance to the median price in sideward phases, when volatility and ATR decrease.
This simplified supertrend can give better results in certain cases, for example in long-term charts, when prices show highly different values falling in a very broad range (e.g. DAX prices between 4000 and 13500).
The indicator behaves more like a traditional trailing stop, because volatility is not considered. The risk of curve-fitting and over-optimization is reduced, because only one adaptable parameter (“factor”) is used.
As always, it should be tried out in every single instance by optimizing a simple trading system whether this indicator or the “normal” supertrend work better.
The indicator should be added to the price window by selecting “settings price – add indicator”. You can colour the indicator or change line thickness yourself using the box “settings simplified supertrend”.
