Charles Schwab

Been with Schwab since the TD Ameritrade merger, had a bumpy start but has mostly settled down since then. thinkorswim is still the platform that is most familiar to me so I do feel kinda stuck here, but it's not like my needs aren't served. Stocks, futures, options, forex are all supported. There are some features that other brokers offer that I wish Schwab would keep up with the times on though, e.g. GTH SPX options trading, an official MCP server, not having to renew my API key every 7 days.
