Simple indicator

Hi,

who would like to create me short term an easy mql5 indicator?

- it should be created for any pair in any timeframe. (only the one which is currently visible)
- colors should be changeable by user.
- all calculations are within the same bar
- the indicator should consist of 3 elements that are drawn in one separate window together:

part 1
- histogram
- default color red
- name "seller power"
- calculation: (close -high) / (high - low)
- this means the histogram always has negative values from 0 to -1
 
part 2
- histogram
- default color green
- name "buyer power"
- calculation: (close -low) / (high - low)
- this means the histogram always has positive values from 0 to +1

part 3
- solid line
- default color magenta
- name "residual power"
- calculation: ("buyer power" + "seller power") / (high - low)
- this means the line can have positive or negative values from -1 to +1

please feel free to ask questions
