What is sidus_app?

sidus_app is an MT4 signal tool that prints arrows where two SSMA lines cross. The original notes that more than ten tools in the sidus series have been confirmed, that they do not come from a single developer and that many variants exist.
The original describes the logic as a simple combination of a moving average cross and an RSI filter. The FastEMA and SlowEMA settings set the calculation periods of the two moving averages.
How to use sidus_app

Arrows appear when the two SSMA lines cross. The original describes the RSI filter applied to those crosses as strict.
The area between the two moving averages is filled in, and the original explains that the fill is drawn as bars when the chart is zoomed in to keep the tool light. The timeFrame setting selects the timeframe used for the moving averages.
