Exactly, that's the only measure that matters - funded, of course, like what's shown on Bittrex. Think about it - do you really care what the current "market price" is or what you end up getting per coin on average if you sell or buy "x" amount? That's the only price that really matters to you - what you get on average per coin when you sell (or as a buyer, what you pay on average per coin that you buy). In many cases, after you buy or sell, the market price clearly turns out to be just a mirage.
In many low-liquidity coins, there is a massive difference between the market (initial) price and the order-queue-determined (average) price. Many dying coins still trading are effectively worthless - they're the walking dead.
Notice that this seems to be the focus of the whale pump-and-dumpers. They focus like a laser beam on the order book. Once buy orders get really fat at a high level at or near the market price, they dump to maximise their earnings. This is why you often see a massive BTC windfall even when the price chart doesn't show much of a drop off in price - yet (the sharp drop off is often revealed later on in the dump stage when others subsequently dump after the whale has into a devestated order book where pricing has been eaten up and destroyed by the whale).
That's why you see the massive excitement over relatively small % price changes in BTC - because those % changes actually mean something. There's a lot more BTC behind them. Back in the old days, DRK, VRC, etc., when they were high-liquditity coins, the market price was or was close to what you got on average per coin when you sold.
The current market price means nothing if there's less than a BTC of buy orders left behind it, sustaining it.
And that's the story of the current market collapse - it's worse than what it looks like if you look at prices alone. There's no real buy support, no real demand, for many of these coins.
