Recently I switched from spot Forex to Futures trading. I understand that one of the advantages of trading Futures is the Transparency of the book and of the actual volumes traded at each price. I understand that the DOM shows the book and that Numbers Bars charts (Footprint charts?) show how much was traded at each price but I’m struggling to understand the difference between the values that I see on the DOM and on the Numbers Bars charts. Also I keep on bumping into the expression “Order Flow”.
Could anyone here please direct me to some good instructional material about those subjects?
