Just documenting a new trading platform competitor as I don't think it's been noted here. Superhero offer $5 trades and have a mobile app inspired by Robinhood. 

One thing that strikes me as hard to understand is their pricing model and value proposition - the two tiers don't make things feel simple.

Here's a write up from Rask Media a few weeks back:

My sentiment echoes that of the article to see how things play out. In the short term, I'm keen to give this new platform a go.
