BTC One of the better "indicators" this cycle are ETF flows to determine strength or weakness at local tops or bottoms. Generally, when we see big inflows after a big run, but price is refusing to move up further, we tend to make a local top. The opposite is true when we see big outflows after a large correction and price is not dropping further on those outflows. In both cases this means that there's a lot of absorption going on and there's participants using these ETF flows to fill only for price to reverse when the buying pauses. So yes, ETF flows can be good for momentum, but also be on the look out for price actually following through. tl;dr Big inflows and no price continuation up = Bearish Big outflows and no continuation down = Bullish
