This TradeStation indicator is based on the idea that the more often the price hits a support or resistance level, the stronger that level becomes. This indicator plots a horizontal histogram at different levels on the price chart, and the longer a histogram bar is, the more often that level has acted as support and resistance in the past.
 
This indicator can be customized to show a combined profile for both support and resistance, or to show either support or resistance separately. You can also choose whether to show the histogram in the expansion area on the right of the chart, or to overlay it over the price data.
