It looks good but what I would like is to have 2 lines when loading this indicator and choosing the levels where they should be on the percentage oscillator - for example 60 and 40 or 80 and 20. I know I can add lines from the toolbar but I add/remove this indicator sometimes and its really unpleasant to draw them lots of times per day.
Please tell me if its possible to happen

Cheers

Is it possible to add percentage lines to this indicator to represent the percentage increase in the Bandwidth. For example a line that indicates a 20% increase in the bandwidth for the current time frame used on the chart?

Hi Apprentice. Thanks for your response.

What I'm looking for is the traditional Bollinger Bandwith Indicator, but instead of it showing over bought or oversold, I would like to be able to see the percentage increase of the the Bollinger Bandwidth over a set period. for example Number of periods: 75 and the scale on the indicator is calculated/represents the percent increase/decrease of the Bollinger Bandwith . The BB_WIDTH.lua caluculates the the output as price percent, Price points and Traditional. Is it possible to add a fourth option that calculates the percentage increase/decrease of the Bandwidth over the specified number of periods?

Thanks,
TraderK
