Trade Failure Check

1. Slippage Ratio

   • Manual buying/selling: It is recommended to set to automatic slippage, no manual adjustment needed.

   • Automated buy/sell orders: Recommended slippage setting is 30%-35%.

   • For new or highly popular offerings: It is suggested to set the slippage to 50% or higher.

2. Priority Fee

   • Transactions without speed requirements: Recommended setting is 0.002 SOL.

   • Automated buy/sell orders: Priority fee should be set to 0.006 SOL or higher.

   • Transactions over 1 SOL: Priority fee should be set to more than 0.01 SOL.

3. Anti-Sandwich Mode

   • Enable anti-sandwich mode: Effectively prevents sandwich attacks by MEV bots.

   • Note: Once enabled, the priority fee should be set to at least 0.002 SOL.

4. Possible Reasons for Abnormal Trade Prices

   • Sandwich bot attack: Trades manipulated by MEV bots, leading to abnormal prices.

   • Too high slippage settings: A high slippage ratio might cause the trade price to deviate from expectations.
