Uniswap is today's volatility flag:

Uniswap is seeing the most action, with 7-day realized volatility at 81 percent, the wildest major right now. Price is pinned around 3.671, right on resistance and the 200-day moving average, with a tightly defined level. It's coiled for a break, but the tape has failed to pick a side so far, expect fast moves once it does.
