To summarize this Alpha trading competition on the S chain, the cost-performance ratio is maximized, provided that you use limit orders (limit orders have no slippage and points x2).
The rules of the event also need to be clearly understood in advance. The trading volume for the Alpha trading competition includes the buying volume and the selling volume, so the total trading volume is the limit buy volume x4.
Based on my different times and amounts, I processed N transactions of 2500U total buying volume and found that the loss on a 2500U limit buy (which corresponds to an actual trading volume of 10000U) is around 7.5U, while the three prize pools are approximately between 200U and 250U (shadow, anon, S). This means that even if you process a trading volume of 20WU, the loss would only be 150U!
