At present, my main robot is a neutral robot with a price of about 2900. Recently, ETH suddenly increased by 20%, so there will be more short positions.
Although I know that robots are a good choice, I continue to experience, think, and improve. If it falls below 3,000 next time, I may open a bullish robot between 2,500 and 3,500, and each bar is still 0.5%.
When it rises to 3500, open 2800~4200, one bullish and the other bearish robot. When it rises to 4200, the bullish robot will end, and then open another bearish robot between 4200 and 3500.
Fine-tuning in this way seems to be able to reduce the cost a little, without significantly increasing the risk. The main idea is that ETH will not easily fall below 2,000 or rise above 5,000.
If anyone has a good strategy, please share it for discussion
