Hello sir. I'm a senior blockchain developer and have rich experiench in smart contract, forking token and so on.
I have done trading bot using Alpaca API few days ago.
If the bot receives signal from indicator in trading view, then call buy/sell action in Aplaca. The user can set his security and account info.
I can provide you user interface to set up a liquidity and dev wallet and swtich these for testing.
I'm pretty sure that I can help you with your project.
We can discuss more detail once you contact me.
Thank you, sir.
