It has taken me months and months to be able to use the Dom with success, but perhaps in not the ways of what most are trying to use it as a scalping aid. I never use it when I am in a trade as smaller timeframes offer me better views of when to close out a trade, but it will tell me when not to enter after an established trend has occurred, Since most of my trades are counter-trend, and I am not a good trend day trader, the Dom can show moments of when the trend is not your friend. I don't look at total contracts on ask/bid sides but each price levels, levels should look like a Christmas tree on bid side, small volume on nearby and increasing as level get away from nearby price, asks are inverted Christmas tree, when these levels get different and depending on number of points in ES from last major low of the day if Price in uptrend is first clue to me that trend is showing it's hand that it will be reversing and that will stop me from taking any trend trades. It is just a small nuance for me to remember, but a loss or two saved each day is huge, difference of having a grand day or fighting to get back to breakeven on the day.
