Post From: Understanding Bid/Ask lines in relation to market depth

I've read through the documentation at Bid & Ask Prices - and from my understanding these lines are drawn from the point of the last trade.

So my question is, it is intended that these bid and ask lines wouldn't always match the best bid/ask according to the DOM, correct?

It seems to always highlight the best bid/ask when using level 1, but in level2 there are many inside levels (even at the time of a trade) that are ignored by the bid/ask lines. Meaning, limit orders that are inside where the lines are drawn. In reverse, sometimes the bid and ask lines are drawn where I don't see any levels located in the DOM.

Just trying to better understand how this works, especially in relation to level1 vs level2 data and DOM. I've also tried using -BID_ASK_TRADE_SYNC with proper chart settings but still see the same scenario. So assuming that's not related.

Also, FWIW, this does not happen on a CME market like the ES. the bid/ask lines align with Dom best bid/ask levels.
