4.0 / 5
For active day traders and short sellers with $27K+ in capital who need multi-source HTB locates, true DMA without PFOF, and a human picking up the phone. Not a fit for buy-and-hold, beginners, or anyone who wants a polished mobile app.
4.3 / 5
Best mobile-first broker for beginners, casual options traders, IRA contributors who want a 3% match, and 24-hour stock access. Significant gaps in OTC, mutual funds, and bonds.
Each broker scored 0–5 across the same 8 dimensions.
