Build software that be used to buy and sell stock to midgate loss

so I have failed to make my own code to buy and sell shares to mitigate loss and make it mostly profit with close to no losses, someone that knows how stocks work as well as coding is preferred. these are the parameters I've set

- watch bitcoin stock price live as it changes through alpaca API
- sell all the stock if the stock starts losing value
- buy the stock if the stock starts gaining value using all the money earned from selling
- needs a GUI to show profit, losses, and total money made, aswell as how many times the program issued and sucsuesfully bought and sold stock.
- using alpaca API or any software that allows me to connect to market software to buy and sell with a program.
- and I would like it to refresh every 5-10 seconds to watch the price and let the algorithm decide if it needs to buy or sell.
- can be in any code format that is deemed fit for this project
-stop-loss mechanism - keying into buy/sell in referencing lines #2 #3 #6
- the GUI doesn't have to be special but if you see a feature you think would be good to ad go ahead and add it.
