Bumping this! I would also like to know more information about this chart/metric. What exchanges does it look at? Is it for the entire crypto market or just BTC (or is it even for crypto)? Does it take into account the size of the buy and sell orders or just the number of them?

Binance, Bittrex, Poloniex on all trading pairs. Based by size of the order. You can also go back and see how it tracks the past quite nicely.
