Percentage ZigZag indicator needed programming in MQL4

Hello

I am looking for an MQL4 programmer fluent in English and preferably a native speaker who can program a Percentage ZigZag indicator with a number of inputs. The details of the kind of indicator i want can be found here: https://school.stockcharts.com/doku.php?id=technical_indicators:zigzag 

At a later date i will also want this programming in MQL5.

The indicator takes its movements from a percentage amount of a previous open, high, low or close.

The inputs of the indicator are:

1. (Heading) Percentage amount

(inputs) 0.1% - 100%

2. Points at which the percentage is measured against

(Heading)  Previous Highest

(inputs) Open - High - Low - Close

(Heading) Previous Lowest

(inputs) Open - High - Low - Close 

3. (Heading) Movements taken by:

(inputs)

Tick

Close of current time period

Open of next time period

Any questions please ask. 

Many thanks 

Graham
