Re: Recognizing a series function based on how it's called. Possible?

All charting packages have the similar indicators and functions generally so there is no problem if you write them from scratch.

But converting lines of code, initialization sequences, detailed functionality, etc., from the original even manually is clearly an infringement. 

I am not a lawyer but I do know that this is not a simple area. I do know that companies who do generate such competing software products take great pains to make sure that the staff they use in the development has not even seen the competitor's code to avoid any possible violations of intellectual property rights.

Writing all that stuff from scratch and properly testing it would take a several man-years of effort if you were lucky...

You can use TradeStation functions lots of ways:

  Avg = Average(Close, Length);
  Avg = Average(Close[10], Length);
  Avg = Average(Close, Length)[10];
  Avg = Average(Close data2, Length);
  Avg = Average(Close, Length) data2;
  ...

You get the idea. Not real simple to duplicate without a lot of testing.
