Uniswap V1 for the longest history. For current trading you should Chart HEX on V2 now.
ethHEX.com is a uniswap front end. The price of HEX there is just the ratio between the ETH and the HEX in the pool there. If someone doubles the ETH in the pool, they get half the HEX that was in it. This would 4x the HEX price. If they 3x the ETH, it 9x's the price. If they 4x the ETH it 16x's the price. if they 10x the ETH it 100x's the price. This works the same in the other direction as well. The price moves as a square.
For example, at writing, if someone traded 4,310 ETH ($2.5M) for HEX on ethHEX.com, HEX's price would go up 4x. If put $25M in, the price would go up 100x. It's awesome to know exactly the effect a single order will have on price. In centralized exchanges, hidden orders and spoofing prevent that kind of simple math.
You can see how much HEX and ETH is in the pool at the top of the v2 HEX chart
Understanding HEX's price movements
Because the most liquid market and dominant pair for HEX trading is the ETH/HEX pair on Uniswap, HEX's price movement will be identical to ETH's price movement unless trades are made on the HEX/ETH pair which shift the chart's shape up or down. If other pairs become more relevant then the charts will begin to diverge to reflect that.
