Just curious! Why would you consider this a "mastery of MQL4" and why is such an article a necessity?
There are plenty of existing indicators that implement multi-symbol & multi-time-frame and in a variety of ways, many of which are also to scale with the current chart. Also (in my opinion) it is not "ridiculously hard to fake". Obviously, it is more difficult than normal indicators but, but like everything in life, some extra work my be necessary. I would say that an average coder can accomplish it with some extra research and experimentation. He/she may need to dedicate some extra time and effort to getting it right, but it is no way "ridiculously" difficult to accomplish.
There is also plenty of discussions on the forum about the very subject and the problem areas as well as the solutions (for example, dealing with the data update delays and the usual 4066 and 4073 errors).
Besides, there are already several articles on the matter for both MQL4 and MQL5 and the current emphasis right now is more towards MQL5 and not MQL4.
It rather looks like you are attempting to have someone code you something for free (and disguising it as a competition, with no actual reward), instead of actually contemplating what I wrote!
Anyone wanting to write such an article can do so on their own terms and does not need your "baseless incentive" to do so!
