Maat LOW HIGH Order is an oscillator based on volume weighted RSI and it can show local lows quite nicely (green arrows). The red arrows can indicate a local overbought area and can be uses as a sell or take profit signal. The length of the arrow is defined by the time frame. Highest time frame -> longest arrow. Arrows can also overlap to indicate a stronger signal.
Shorting on red arrows is not reliable yet.
Huge part is the multi time frame addition, so you can get a confirmation from multiple time frames on one screen.
Check the settings I used for 1h chart. Lower TF also possible, just change the settings accordingly.
To make this even more precise I incorporated my HORUS script as a filter. The HORUS checks the spread of two tickers and may indicate oversold / overbought conditions compared to one or the other (Eg. BTCUSD and SPX500).
That way you will only see green / red arrows when HORUS is also showing some overbought / oversold signs.
