Post From: Offering To The Community: Up/Down Volume Ratio With Limiter By Tick With Filters

I've been programming some indicators from my base tool kit and am offering them to the community. I request they be added into the main SC distro once checked over.

From the "Display Study Documentation" button:

Up/Down Volume Ratio With Limiter By Tick With Filters. To properly use this indicator, Sierra Chart must be set up in tick by tick mode with intraday bars. If all "Input Data" options show a straight line at 0.0, then tick by tick data is not available or not enabled. Note that some volume data is only available when the market is open.

This indicator uses the traditional Up/Down Volume Ratio but adds a limiter to reduce the value on low volume. This helps reduce the large ranges on low volume that can blow out the scale. With the limiter in place, this is not a ratio with a 100% scale. It is very similar to Up/Down Volume Difference but much slower to calculate because of searching for the Highes Value average. The Highest Value average takes the selected number of highest values for a time period and averages them to a high value line. Anything above the line is ignored. Anything below the line gets the output ratio scaled proportionally by the limiter. Despite the higher number of calculations per bar, this helps identify which of the big peaks/dips are real or not. This indicator solves the problem of the ratio line jumping on each new bar with little data. This also makes it easier to use with automated trading systems.

This indicator version has a second smoothing option. The ratio data is very choppy and extremely noisy. The second moving average can be of any type and will help clean up the line. Smoothing with a larger number isn't as effective as double smoothing with a number half that size.

This indicator version has a Volume Filter option to handle cases when a volume spike smashes the indicator making it hard to read. Large institutions sometimes do this to hide their activity afterward. The "Straight" option passes volume data through without any filtering. The "Log" option runs each volume bar through the log function making a type of "log scale". The "Square Root" option runs each volume bar through the square root function making a type of "square root scale". The "MA Clip" option will clip volume above a chosen moving average.
