Price follows volume.
No transaction(s) = No price print(s)
This is not clear to me. Can you show with an example how price follows volume?
The way I understand it - price moves because of liquidity imbalances, i.e., market orders (liquidity takers) overwhelming the available limit orders (liquidity providers) at a given level.
If the supply was unlimited at a given level, say 4700, price would never move higher regardless of how many market buy orders were hitting the market. So, high volume, but price won't move one tick.
However, if the available liquidity is thin - the market will frequently move quickly higher on even low volume.
In fact, this is how I've come to understand how markets work. It's nothing other than matching of orders day in and day out.
In markets that are less liquid than ES you'll have price gaps where price will actually jump between levels with no traded prices in between. And maybe the last quoted price won't be traded either. But that price can still be there as a quoted price, i.e., price can exist without volume. But volume can't exist without a price traded.
Thank you.
