Need Help Coding an Indicator MT4

Please code this idea into MT4 indicator as i do not understand MQL4 despite my trying for it.
The idea for weekly and daily bars is (May be applicable to all TFs)

Sellers=High-Close
Buyers=High-Open
1. Sellers/Buyers may be indicated as percentage of whole bar length that is High-low of the bar.
2. Same data may be shown against last 20 bars against each bar in the mathmatical form.
3. the indicator should also average out buyers and sellers of last 20 bars over the last lowest low and higest high of last 20 bars as a percentage of of 20 bar total range.
4. The number of bars should remain variable so that can be adjusted by individual trader as per his own needs.
5. The indicator may please be developed in indicator form in the lower pan or may be developed in mathmatically form with price.
6. Any developmental idea will be appreciated
Thanks and help will be highly appreciated.

Hello,

Check MT4 built-in indicator named William Percent Range (Insert-indicator-oscillator). To understand the underlying math of this indicator, see Help on MT4. Select Search tab, and type William). Based on your description, I think this indi does exactly what you need.

Hope this help

no body seems ready in helping me out as this is not my own idea and its the combined idea Larray Williams and TDM and in turned into some indicator can greatly enhance the viability of that idea and definitly trading too.
so please step forward and help in making this indicator

Youve got to be willing to spend money to make money. And if you arent willing to spend money on a super duper indicator than I guess it just isnt that good of an idea, now is it.

Try going to scriptlance.com there are several mql programmers there and will also code it, for a fee of course.
