Show HN: Trade stocks from the command line with no commission
(Disclaimer that I'm working on an open source FIX engine in Lisp.)<p>This is a really cool project! But alas I couldn't use it as I'm not in the US, and I don't trade with Alpaca. And I feel like this plays into a negative trend I'm seeing.<p>The retail brokerage market right now is treading on similar 'mistakes' in institutional markets 15ish years ago. Proprietary APIs were prolific, and therefore increased switching costs and lock-in (looking at you, Reuters and Bloomberg).<p>On the one hand, retail brokers need to support popular programming languages and paradigms to gain traction. So, they are releasing http-based APIs, or popular language-specific libraries/bindings for their proprietary APIs. But, they are doing this instead of pushing well-publicised battle-tested standards such as FIX[1], that would normalise the playing field across brokers. So my gut feel is that they are banking on users coding against their APIs and having some lock-in effects. Notable exception is that any broker that supports cTrader will have a FIX API, because cTrader provides that for them.<p>The problem is: if I write a bunch of code to work against Alpaca, TD Ameritrade, or whoever, that code will likely need to be revisited for some other broker like Robinhood. Granted, market connectivity code _should_ be well abstracted from my model if I'm following good design principles. But at least with FIX, the core concepts, fields, and messages remain the same across most FIX endpoints (NOS, ExecRpt, etc), allowing for a more uniform code holistically.<p>[1] <a href="https://www.fixtrading.org" rel="nofollow">https://www.fixtrading.org</a>
