Fulcrum / fulcrumlend.com offers copy trading. I copied a top trader. The copy trades often executed at worse prices than the original. When I asked why they said it was due to latency and liquidity. So the feature is broken or they are skimming. Either way I stopped using it.
Pros: Low minimum deposit|Intuitive for beginners
Cons: Charting tools need more indicators|No fractional shares
