When the event contract was first released, you could easily win by simply looking at the Bollinger Bands and catching the reversal. But after a few days, it was no longer possible. The price would always stick to the Bollinger Bands for a long period of time. You had to look at the KDJ plus the MACD and enter the market on the right side to barely make a profit. Moreover, if the amount was fifty or one hundred, it was easy to be sniped by the sudden change in the price at the last minute. I was depressed after being sniped for a few days, and I didn't believe in evil, so I changed it to 5 dollars and 10 dollars to see what you can do to me. As a result, now I don't care about salt. Once the liquidity is poor, 5 dollars will give you a precise sniping
