Alpaca

Very simple and good platform. I guess even if it's not its core, it's lacking a bit of UI features.

should have summary rows on your total holding positions, how much "real buying power" there are.

Love Alpaca as my broker, I get personal attention as a new business owner. Caring company, no fees, very happy with them

Is a very convenient way to trade in the 21st century!

Great for running my bot.

API is the best way to go for trading.

Love it. As a want to be quant/algo trader it provides all the tools to get started.

A 4 star platform with negative 2 star support. Here are some actual situations: Trading begins at 6AM PST but support doesn't get in until 9AM PST. Alpaca has a bug which doesn't reset the quantity on cancelled orders which leads to insufficient qty when selling. What's support's official resolution to this? Use the "cancel all orders" button. "ALL" orders which cancels Stop Losses and Take Profit.

COOL once you figure it out

API access

It's okay but I can't place a bracket order with my Alpaca account, it doesn't show cash available, and doesn't show number of day trades in the rolling 5 day period. Also can't place trailing stop but that is Alpaca's fault. Overall, not bad. Average. So 3 stars, right in the middle. The only way you get perfect 5 stars from me is to have a perfect interface. Just really really good only gets 4 stars.

It has had some growing pains, but is a really great service, overall.

System goes down too often.

Missing stop loss functionality

good service so far, needs a little more definition on charts

Fast approval, interface is great. EDIT: reliability issues and can't do stop losses at the time of original orders.

so far so good, haven't try with real account yet but so far so good

It's a one-of-a-kind service, and I really appreciate having it. However, the streaming connection seems buggy and disconnects a lot.
