Many people may have some misunderstandings about why I want to calculate the probability of $Invesco QQQ Trust(QQQ.US). Many think it's gambling. What I think is, once I have dozens or hundreds of voting indicators, a consensus can be formed, which can increase the accuracy of evaluation. Whether it's a positive indicator or a negative one, it's very useful. Compared to the hundred-fold leverage of doomsday options, if this indicator can be more accurate, it will bring huge profits and has very high reference value.

And if you only look at these few days, it's meaningless. Once a consensus is formed, everyone who can see this indicator will find it easier to judge the direction than those without it. I'm doing this for everyone's future, not just the present!

You must look further ahead! There are also people who bought stocks and ask what to do as soon as the price drops a little. If you don't understand at all, just sell it. Holding it for one more minute is unnecessary!
