No arrays/vectors, just one data type (floating point numeric) and no OOA.
It’s a very easy language to learn even for people with no previous knowledge of programming languages, a subset od the BASIC language.
Indicators are actually functions.
The lack of arrays and string data, along with runtime interaction with strategy and/or the user, are the improvements that would be much acclaimed and all of us hope they will be supprted in the future (not shortly, I fear).
