Are there any services out there that allow automated trading, but as a game? There are many services that let you do manual trades as a game, but I've never seen automated ones.
Interactive Brokers also offer a paper trading account that can be traded via their API just like a regular account, although you need to have an account with them.
There are some limitations on specific order type/venue combinations, but most things are supported.
Nah bro. You can try their demo account. The login is 'edemo/demouser' and you can use it via their API as well. The only issue is that the demo account is not persistent, so you'll lose your positions the next trading day lol. Plus there are tons of peeps sharing the account trying to test their trading bot as well after-hours. But if you're just doing daytrading QA, it's pretty good.
