You'll see this a lot today.. you can find this indicator on TradingView called "Hash Ribbons" use the Daily TF.
This implies we have put in a Macro bottom. Does NOT mean prices rises today or this week. But, overall it's time for a bull market.
In 2018, Hash Ribbons flashed red and we saw a 50% drop followed by macro bottom. Once it said Buy, it took 28 days of slow grind lower until we saw the beginning of the Bull rally.
