I have spent most of my life studying chart patterns and have identified over 20 formations that have over 51% chance of reversing. Most would say not high enough probability of trying the effort, but if you found ways to do so without loss or very small negative percentages, certainly it worth the effort. But is it worth retail accounts, costs money to make money, meaning you need more than small account to act upon for correct hedging.
I had been shorting Indexes for nearly 3 years before virus hit and caught move down on futures and hedged long dividend paying stocks.
Long term and even shorter swing trading is like fishing, you never know when the catch will be a whale or guppy, just got to be a monkey and keep putting on the trades and hedged.
All trading is forcasting, we have no cystal ball with exception of having all the answers in place before the questions. And took over 30 stabs at it and, can make some profits when you don't find overall huge trade.
Have to be patient.
