Thanks, I have to admit that the Investopedia article still left me puzzled, but I found a YT video which helped me to understand it better, from the institutional investor's point of view.
Oh my, this guy likes to talk. Bore me to death saying the same thing 10 different ways without actually presenting any real examples of where PAIN works.
Here are my basic rules:
A. From my experience, MaxPain doesn't work reliably with most individual stocks.
B. To be labeled a useful tool it needs to be back tested for years. I need it to be successful more than 70% to be considered. It needs to be spooky accurate for me to add it to my tools. Plus, there will need to be recognizable parameters for it to work reliably. You need to know what they are. That sounds simple, but anyone who takes MaxPain and tries to apply it to Meta is wasting their time. That's not its forte.
C. The next step is identify where Pain does offer an edge. There are zero tools that will give you 100% wins all the time. If you understand that, you look for tools that show you when you are moving with the tide versus against it. Combining those insights with a single strategy can improve odds.
D. From my observation, the S&P 500 is one of the
few places where MaxPain works reliably to identify high opportunity dip buys. I look for situations where price is lower than PAIN by 6 to 12 points. Over 10 SPY points and you almost always see a bounce within a short period. Those opportunities happen typically less than 10 times a year depending on how volatile the market is.
E. It's unusual for a down market to be saved on a Friday. So many times when a MaxPain opportunity occurs it's a patten of Wed, Thurs. down and Friday puke. That type of activity can reach a price 10 points under PAIN.
F. Using PAIN to get out when price is 10 points over MaxPain is NOT reliable. The market can simply keep going higher - so don't expect it to time PEAKS.
G. MaxPain can change and usually does as the week progresses. A flexible strategy which changes with data is required.
