Automatic/progamable Trader Bot for price controlling

Is it Possible to run an Automated Traderbot for the stable operation of a “Tether Coin”?

such a bot would neverendingly have to observe the markets for example token/usd exchange

and then if there is a price drop or price overhike, the Traderbot will buy back or sell the considered Backed token

did someone so far experimented with that?

regards

It’s not difficult to do this, but I guess there is no ready solution.

would be quite useful right? to operate fiat pegged currencies
