stockstream

I'm quite certain its ok to share referral codes in that way- I've referred probably thousands of people though my project.

Shameless plug: https://stockstream.live/

There are no protections against trolls. At this point a dedicated group of less than a hundred could probably take over the vote.

I'd actually love to see more dedicated troll attacks. So far the main attack seems to buy $SEB since it's so expensive, but sometimes it later gets sold at a profit.

Personally, I've mentally written off the $50k so, I'll just be enjoying the show.

Actaully the pubsub part is pretty core to system overall. Basically I have a set of 'operations' modules each operating independently (gathering news, tweets, votes, stock quotes, etc). They publish that data over the pubsub system, so that all the subscribers (mostly in-memory caches) read and update accordingly.

Game events also get published through it (round end, trade placed, new round, etc)

Thought a lot about this during the development period, but nothing materialized. I might do it someday but would probably need to ramp up the scoring algorithm first.

One of the reasons I decided to do this project in the first place is because nobody has ever done this before (at least based on my research), and I wanted to be the first. There are plenty of stock simulators out there, so fake money didn't sound appealing to me.

Actually, those two bits are pretty small. Theres a ton of code all over github for interacting with Robinhood. The twitch chat API is really just IRC. Glueing those together was the easy part.

The more interesting and complicated components are the UI and the scheduling and a publish-subscribe module that I created, tho no plans to open source it anytime soon.

Thanks! Seems word spread through the extended family pretty quickly.

We should stay in touch though, add me on LinkedIn if you use it:

If you'd really like to, just scrape the twitch chat yourself, count the votes and invest accordingly!

Yeah did some initial research, but didn't find a good platform with an API and no fees.

No idea. Was bearish at first, but lately a lot more bullish. Only time will tell.

Just gonna hire someone to do it for me.

Yep, I use OBS. Its awesome, thanks for all your hard work on it!

The $50k is all mine. I was not given anything from Robinhood except for approximately $500 worth of free shares for referrals.

You can learn more of the $25k rule here: https://support.robinhood.com/hc/en-us/articles/217072366-Pa...

Actually, there kind of is. It will stop you from placing trades if you daytrade with less than that. Your account will be suspended.

I found a bit of code on github to access the robinhood api. That bit was actually not too difficult to implement.

The regulation bit not special, just a restriction on what trades are allowed.

Yes

Ah yeah, hey, how's it going? I remember you from the YYZ office.

Heh, well I definitely don't consider myself to be super wealthy. $50k is not a small amount for me, but not the end of the world if I lose half.

Some shares were gifted for free by Robinhood for referrals.

Nope. It actually is my real name.

>And home much can you trade at once?

As of current rules, you can only make one trade of one share every five minutes.

I will likely change and tweak these rules over time.

StockStream was launched independent of Robinhood. I really like their platform, so am glad to include links to their site.

Hey everyone! Glad to see you're all enjoying the project. I'd be glad to answer any questions you have. Let me know!

Unsure, though would guess probably not. They apparently have a nontraditional method of executing orders, see https://archive.fo/hf0rt

Using the Robinhood App allows trading with zero fees. Additionally, Robinhood has a feature called RobinhoodInstant where trades are settled immediately so funds don't get stuck in pending settlement.

Only 1 share can be bought or sold every 5 minutes. In some fairly naive simulations this system was ran against, it would take weeks and months to fall below the 25k mark.

Voting weights can be introduced to mitigate spamming and round lengths can be adjusted to mitigate other issues.

It could turn out a complete disaster, but it will be a disaster in slow-motion.

Effectively allowing anonymous strangers on the internet to control my brokerage account containing $50,000.

OP here. I re-registered to reflect new branding.

The backend is actually not too complex. Commands are processed from Twitch using PircBotX. Then, that and other data is vended through simple APIs created using SparkJava (http://sparkjava.com/).

It's effectively an API + Web server connected to by OBS Studio Browser instances.
