Finding best protocol for pair #73

Open spprss opened 2 years ago

spprss commented 2 years ago

Hi, since you recommended not using 1inch anymore I started redesigning the bot. I encountered the problem that we don’t know the „best“ protocol anymore. Executing the bot for every protocol makes no sense since cyclic arbitraging needs more than one pair. So i tried finding the protocol by asynchronously checking all exchange rates and returning the highest rate giving protocol BUT this causes the bot to fail at some point if i set low intervals. To summarize all my tests with different strategies the last weeks: i didn’t quite found the best performing solution for this :) since your private bot is profitable I’m highly interested in your strategy of finding the protocol!

Hey spprss, can you please teach me the step to step how to change the inquire way from 1inch to the defi pool directly, I can read those codes, but really have limited knowledge of how to make a change.

Here is what I found so far, each time there is quite profitable, and with like 7 sec delay, everytime it was unsuccessful. https://polygonscan.com/address/0xf651b785aa4aac0edcf2220ad88a9d2b52f640ff

Thank you for sharing it. That's true. However, that way increases the slippage since it take a little before the flashloan tx. So, even if you find the best routes, you will end up missing the opportunity since the prices changes really fast.

I think it is more important to execute the flashloan fast even it's not the best than do it with best routes and pairs.
