Contracts will only infinitely expand the greed and desire of human nature. No matter how good the strategy is, once people get carried away, they will become leeks. To invest, you must continue to do things with a winning rate greater than 50% and constantly improve and improve the winning rate to obtain positive feedback. I will still work on my robot grid. Reporting the battle situation in the past two days: After the contract on the 10th was liquidated with 5000u, the TST short grid went from 70u to 600u with 7 wins in one day; from 1000u in the afternoon of the 11th to 3300u at noon today (a small episode in the middle tried the layer with 200u, but fortunately I was scared off by the high funding fee before 4 am and stopped the loss). Now keep 1000u in the capital account, and continue to fight with 2300u. In the future, bn will only work on robot grids, and will continuously update the results. Please supervise and urge the manuscript. If you need strategy parameters, you can comment in the comment area. I will reply to you privately when I am free. $TST
