Solana automatic trading bot

I want to create an automatic trading bot on Solana (build in Javascript). My strategy I want to be something like this:

• track all the tokens that show up on pumpfun

• filter tokens by certain criteria (website, tw, luquidity). I don’t know here which filters would be better but still reading. If you have some advice please share with me.

• and buying strategy to be something like this Set Auto Sell to 10% profit, 5% loss

• and have a number of trades open at the same time.

Do you know if there is something already implemented?

If you jave any sugestion fell free to share.

Thanks.
