This is a bid-ask pressure indicator for tradestation trading platform. All credits go out to the author of this indicator from the tradestation forum alias lleibfarth.

Here is a description from his post:

Description: This indicator is a smoothed version of the TS indicator Bid & Ask Vol Ratio and works with real-time, intraday charts. The intent is to provide more usable information about the current ratio of bid/ask volume. This indicator will not work on historical data (it must be used during a live intraday market) and is relative to the chart interval on which it is used. I have found this indicator to be most useful in shorter charting intervals.

How it works: The data is smoothed using a double-smoothed exponential average that heavily weighs the most recent ratios. This provides a relatively predictable curve (or histogram) that tracks changes very quickly. In addition, a logarithmic ratio is used to provide a zero-line reference (and color change). "
