This indicator is coded to run on Trading View which was originally created by traderathome (TAH), qFish, and all other respective contributors for the mt4 version.
You can select to display the lines (SR) using either the Daily or Fibonacci formulas.
The Fibonacci displays five levels.
Normally, the Daily displays only three levels but is extended to include five levels.
Due to the short TF it displays, the indicator would only appear on TF 1H and below.
