Ask HN: What software/services/apps to you use for stock market trading?

I've been wanting to invest in the stock market for a while now, but I don't want the overhead of having to go through a traditional bricks-and-mortar brokerage firm to buy/sell stocks.

I've looked at a few online services such as Robinhood[1] however it requires US residency which is unfortunate, as it looks like a great solution. I've also seen Drivewealth[2], which only exists as an iOS app.

I'm wondering if anyone has suggestions on what they use, be in in the US or not. Are online services worth it? Or is it best to just go down the traditional brokerage line?
