SL trailing class

Hi.

I am looking for a MQL4 programmer that is familiar with object-oriented code and would design a trailing class (in MQH format) for me to use in my own EA.

The class should take a ticket number as parameter and ideally is should be designed with reusability in mind, meaning that a base trailing class should be designed with core functionalities and then inheritance would be applied for each variance of the trailing method to be used. This way, I could add new trailing methods in the future.

I will provide further details to the selected coder, but basically you must at least implement these 6 trailing methods: SMA, ATR, MA cross-over, bar High/Low, Heiken-Ashi, Fractal and provide a working demo and some sample code. 

 Thank you.
