Ask HN: I want to get into stocks and options

I know this may seem like not a thing to ask in this forum but I think it's the PERFECT place to ask. A bunch of technically apt people seem like the perfect place to pose this. What platforms for stocks and options do you all see as "the best"? Low cost, maybe has a scripting language built in. Trustworthiness. What resources should I gather together and learn? What kind of pitfalls should I look out for? This seems like the perfect system to take apart and learn about.
