The reasons for the big gap between the double quotation and the firm offer are as follows: First, the double quotation is a double quotation, and the trader is a trader, so what is summarized in the double quotation is useless. Second, simply look at the data after the resumption and summarize the rules by memory. In order to achieve good results, you need to list the discovered rules one by one, and then repeat the game for at least five to ten years according to each rule, and count how many times you have succeeded and how many times you have failed, so as to get the statistics of winning percentage. Only by doing this, can we achieve a real resumption, rather than simply looking at the data. I made a new statistical table for your reference.
