Hi, is there an API end point available to pre-borrow stocks before the market open of a day, or a day before?
I’ve asked the same thing before, and currently Alpaca doesn’t support hard to borrow stocks. There is an ETB list for stocks that currently fall under the easy to borrow bucket; those can be shorted via Alpaca.
I currently use TradeZero for shorting HTB, and Alpaca for everything else. TradeZero doesn’t have an API, but I’ve hacked together a Python library that piggybacks on their web app’s websocket endpoint to provide an automated way to locate shares and place trades. Happy to share the code if you’re interested; just reach out.
