MooMoo has a price index  algorithm built in, I have been using MooMoo for about a year and just discovered this, click on your favorite ticker and scroll or find capital flow. It tracks and plot the "tape" allowing you to see changes in price direction before the candles print. works great for finding exhaustion, bottoms and divergence. When price is going up but the line is going down you can bet price will revert to the line direction
