I used a small amount of funds to operate a grid trading robot for a few days, and I found this robot to be very stable. It can avoid emotional trading and also allow for some small profits. Even if there are losses, they're not significant, and at times, I could still achieve positive returns through fluctuations. Moreover, these losses were largely due to my own caution, which caused me to incur many unnecessary losses. I opened a short selling robot for Baby, but after cutting losses at the peak, Baby continued to fall until now.
