Modification of support and resistance indicator

Hi,

I would like to make a modification to the attached support and resistance indicator. It’s working by painting support and resistance levels onto the charts (the lines / dots in the image below). 

As an additional, I would like to incorporate a moving average (EMA) into this indicator (which can be adjusted in parameters). The aim of it is that once the support and resistance signal is painted, it will also give the value of the moving average on the charts. For example, please see 4 example candles below:

Careful: It is NOT the support and resistance level, but the level of the moving average at the time the support and resistance level is printed.

As an additional step, I would like the indicator to compare each resistance signal to the last resistance signal that was painted and check if the value is smaller or bigger. If the value is smaller, the number will be printed in red, if the value is bigger, the number will be printed in green.

EXTRA Feature if possible:

As another additional step, I would like to compare each resistance signal to the last resistance signal that was painted and include the percentage increase or decrease of those two values, rounded up to the third decimal place) Please two examples below:

Any questions please let me know.

Thank you
