Wrong method.
You need to use :
value1= average( expression)
value2=vaerage( value1..)
value3=average(value2..)
According to the context , a different average user function is used ( see the average function listing in the power editor).
Thethe calcuations are faster than what you expect.

What is a multidimentionaml array of series!!??!
A mutidimentional array is de facto containing series if you update the matrix cell when necessary!

EL is not C++
You have he right to compile a DLL tat use pointers and call it from EL if you like it.
I cannot see a difference in compiling a pointer code in C and compiling a DLL using pointers in it , then calling it from TS EL.
Suffice to say that the need of this kind of calcuation is above the average trader and even seldom used by a proficient EL user.

Old time was so good and sweet to my memory when grand'ma have explained to me the subtle paperwork of grand'pa using point and figures for trading on brown paper bags.
Then she gave me a piece of cake with a lot of maple syrup...

No.
We cannot expect the intelligence of TS3 users
