MultiCharts: Trading Software for Automated Trading and Backtesting

I accessed q_bid and q_ask in PL and noted that while the compiler allowed q_bid[1] and q_ask[1], the same numbers are returned. Is this correct? The compiler allows q_bid and qBid[1] but they are equal?

Further how do I determine the size of the bid and ask?

The bids and asks are received from the status line only, so there's no history available for them.

Thanks. Is size supported?
