Repair and Improve Level Sensor Indicator

Hello,

I found an indicator online. I installed it and it is not working perfectly.

There appears to be just a small glitch in the code somewhere.

The indicator is supposed to report volume on the right edge (vertically) by price. Right now the indicator displays in the middle of the chart and covers everything behind it.

The repair would be to resize the bars and make sure they display on the right edge.

It would be best to have no overlap of the chart and the volume bars. 

We could also think about an overlap but the volume would need to be in the background so the bars over it can be clearly seen.

I would also like someone to be able to explain exactly how the bar is calculated since there is no volume data available that I know of. I am assuming it is counting the number of ticks at each price level which maybe all we can do.

I would like to be able to improve this indicator by being able to choose different ways to display the data.

For example

How many days or hours of data to include in the bar depending on the chart used

such as,  on a daily chart 365 days worth of data would be advantageous but on a 5 minute chart perhaps only 3 days would be chosen.

I should be able to determin how many days or hours worth of data should go into each charts volume bars.

 It would also be cool to be able to break this data up by session Asian London New York giving each session a different color. This could be displayed on a single graph on the right edge or at the end of each session.

I would also like to be able to turn on or off the display (by a labeled line) of each sessions high and low. Line Asian High, Asian Low, London High London Low, New York high New York low. There should be an option to change the number of days highs and lows to display.

I am looking forward to working on this project with someone. I am easy to work with, no pressure, lets just get it correct. :)

I have included a couple files that may be used to borrow code or give ideas about ways to do this.

I do not spend all day every day at my computer so if I do not respond right away, I will as soon as i can.

If my budget is not realistic, let me know what you think is. 

Cheers
