I was doing these kinds of trades in early 2018 before the coin market tanked. Works great in high volatility. Don't be scared to catch a falling knife with the right research and patience.
1- Find a level - multiple confluence of levels are best 2- Look for divergence for possible change in direction 3- Look for higher volume bars compared to recent preceding bars that were lower volume.
Hit rate is high on these if you are not greedy. Balls of steel also needed to counter against heavy volume, but with the right location, you can grab from the market.
