We need to be able to half-span the Hurst Bands – Historic (price bands). We have been using Esignal’s Hurst Bands for several years but believe they would be more effective if we could half-span them. In other words, we’d like to be able to push 120 day Hurst Band back in time 60 days, or a 60 day Hurst Band transferred back in time on the chart to 30 days from the last day of trading. We’d like to be able to do this on monthly, weekly, daily, hourly, and down to 3 min charts.
