Post From: ACSIL market depth / market-by-order data consistency and OrderQuantity semantics.

No definitely not:
do sc.GetBidMarketDepthEntryAtLevel() / sc.GetAskMarketDepthEntryAtLevel() and sc.GetBidMarketLimitOrdersForPrice() / sc.GetAskMarketLimitOrdersForPrice() read from the same internal market depth state?
These are completely separate from each other. And separate streams of data.

There is no recommended way and there is no guarantee they would be consistent:
is there a recommended way to obtain a consistent view?
But the degree of inconsistency if it exists is not known either.

And also market by order data for quantities below 3, are not even included.

We are not sure about this:

2) Does n_ACSIL::s_MarketOrderData::OrderQuantity represent the displayed quantity of the order as disseminated by the market data feed, excluding any hidden or reserve quantity that is not displayed?
It is what the exchange is providing in the market data feed.
