    build me an arbitrage bot 1 Tag left

    I need an arbitrage bot that needs to be developed so that it can utilize flash loans to make arbitrage trades on platforms like Uniswap, Sushiswap, Balancer, and other reliable DEXs. The bot should have the ability to scan for opportunities and detect price differences between exchanges. Once an opportunity is identified, the bot should swiftly execute flash loans from Aave or Dydx to execute trades. The bot should determine the necessary flash loan amount (collateral) and execute flash loan arbitrages with the appropriate gas fee to avoid being outrun by other bots. The bot should also automatically and simultaneously repay the flash loan, pay the gas fees, and send the profits to the wallet address of the owner.
