Take the GomiLadder or Market Delta for example. Lets see if I`m understanding this correctly:
Simply adding up the total Bid/Ask for any bar does not equal the actual volume of that bar as Bid/Ask may tick at different prices but not trade at some. Please correct or expand upon this, really like to understand it better.
The Delta of the same bar above would be any traders that hit the bid or lifted the offer. Trades that happened between the Bid/Ask (reasonable frequent in the CL) would not be counted.
