Excellent!
The following questions are probably premature, given that your plans for this "language" are in the making, but bear with me...
I am wondering if it will be possible to access the L2 order book data from within the language (it would put MT at the top of the pack in terms of capability)
Also, will it be possible to access account-level data (margin use, open orders, etc.). If yes, will this be event-driven, or will polling (snapshots) be necessary?
I am thinking along the lines of being able to develop entirely automated trading strategies, which would need feedback on what is going on with the account and also order status, etc.
Can we look forward to all of this?
