You might enter any of them, but my recommendation is to choose the AMM protocol as the first connector due to the order execution being slower than centralized exchanges. Filter. I always withdraw profits and start again with 1 ETH at the start of every week. If there is still a potential profit, the order is executed. A transaction on Balancer smart contract will use around 50k gas + 100k gas/pool used on the swap.

It seems pretty simple since we only have 3 equations now, we can get the representation for ${\Delta_a}'$ in ${\Delta_a}$, then calculate the derivative of ${\Delta_a}' - \Delta_a$ to find out what the optimal ${\Delta_a}$ is.

The Uniswap protocol is the largest decentralized exchange, with an average monthly trading volume of over 50 billion in the last 12 months [1]. Since they know they have purchased at least as much as the current price dictates, they are able to instantly withdraw that amount (although it is likely they will actually have purchased more than that amount in total at a lower price). \Delta_c = \frac{\frac{rR_1R_2}{{R_1}'+R_1r}r\Delta_a}{\frac{R_0{R_1}'}{{R_1}'+R_1r}+r\Delta_a} \tag6 Arbitraging with 1 ETH, the blockchain transaction cost will be: We add this number to the total trading fee on both legs (0.1% on Binance and 0.2% on Balancer).

If you know Javascript, you could use web3 to calculate how much gas a smart contract interaction would use and incorporate it into your trading.
