Other programming language like mql5 -> That permits to analyse the depth of market , order book ?

[theleolight]

I've seen some other languages like mql5 , but they were really basic and did not permitted the study of the order book ; like , they didn't had equivalent for "a=book[0].volume" for example , just to give an idea.

Is there any other trading programming language that has a equivalent for these kind of requests ?
