Volume Support/Resistance

An Indicator which shows the potential resistance/support level at K bar with significant trading volume.

The logic is stated below:
(current K-bar volume - the past average trading volume of 48 Ks) > 4 *standard deviation of trading volume
When this condition is met, it is considered that the trading volume is particularly enlarged, which may be an area where support pressure is possible

If the K is an ascending K-bar, then draw support at the lowest point; if the K is a descending K-bar, draw resistance at the highest point.

You can change the length and the number the standard deviation in the input section.
