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.
This indicator helps to enhance the visuals of the current price at the whole, half and quarter levels.
From time to time when there is a surge in price, the indicator might produce diagonal lines. If that occurs, simply switch TF and it should disappear. Otherwise, refresh or restart the indicator.
Hope you understand!
