Hey AlexeNP, I've been following you with passion for your 1000 different ways to play with math. The markets suddenly started selling heavily today, and I thought I'd ask you a question that may or may not require a lot of math. Do you think it is possible to determine in advance with the help of some mathematical model / equation whether there can be such dangerous movements in short-term trading as today? In this way, large drawdowns can be avoided. Can you address this specific help for us? I believe that you can make any algorithm because I have seen 1 million indicators, but your indicators are much more complete, powerful and original than others, so I wanted to make this request directly to you.
