Never got a verification email. So I don't know what it offers, but I'd say it should allow shorting, if it doesn't already.

It does not as of now, but I’ll be working on shorting soon. The goal was to initially find good long term companies to invest in.

Regarding the verification email, I’m using Firebase Auth now, will figure out the cause. Thanks for letting me know! Have you tried resending the verification email?

oh hey this is cool, I'd like to start investing some time so this seems fun to play around with first

I’ll be writing some articles as posts on the site in the coming days, hopefully it’ll help you get started!

I did check my spam folder and it didn't get any messages. But now, the third email got instantly delivered, into the spam folder (hosted by Fastmail), and I marked them as Not Junk.

Some more question/feedback:

- Is it a design decision that the commissions are high? I got 13 cents per share (on a stock priced at 49.89). I would expect more like 0.35 cents per share. I suppose that is forcing more long-term holding...

- I already find my trading in this website is not representative of my positions held in my actual portfolio. It's a lot less well balanced.

- I could trade when the market's closed -- at 3:10 AM ET. But S&P, Dow, Nasdaq, and Russell 2000 futures are running overnight. So that opens up a possible arbitrage. There is a similar one on individual stocks for any after-extended-hours news -- such as selling TWTR before pre-market hours on Friday (Oct 21).

- When I search for "BA" in the ticker lookup, the option "The Boeing Company - BA" was way down the list. The search box should prioritize exact match ticker lookups over company name lookups.

What's up with the "get paid" page? Are you selling real subscriptions to insider knowledge for people's fictional portfolios?

Actually, I'm not selling anything. The authors themselves get to sell subscriptions to their readers when they gain reputation. Yea, it's fictional, but hopefully it will be a better proxy to their value as compared to outright selling a newsletter subscription. Plus, authors can only start selling subs after 6 months, and no one would subscribe if their ideas are bad. I'm trying to build a skin-in-the-game kinda sy…

FWIW I understood it pretty easily.

IMO a big thing these sort of simulators always lack is a notion of tax consequences, which is always a big factor in real decision making.

Could you explain a bit more? Do you mean that the decision of what to buy and when to buy/sell is informed by the tax consequences? Interested to learn more.

The most obvious one is holding for at least a year to avoid being qualified as short-term capital gains. There are other relevant rules too, for example look up "wash sale rule".

You’re right. Currently high frequency trades are penalised by commissions which has a fixed component. I’m still banging my head trying to figure out a simulated tax environment, but I’ll get it done.

The goal is to make it as perfect as it can as an imperfect proxy to investor skill.

Firebase is annoying damn. Will figure it out.

(1) yes high commissions are designed to promote long term holdings (hence the name of the platform). I’m still trying to figure out simulated taxes.

(2) hmm, do you mind elaborating? For me, it’s not an exact replica of my personal portfolio, but moving forward it should be a relatively good proxy to it.

(3) I think the commissions itself will eliminate profits from minor arbitrage, but large deviations are possible to arbitrage successfully. Thanks for this, I’ve added a ticket to solve this issue. Will implement open market timings for trades.

(4) Search is far from optimal for now... super rough MVP. Will improve of course.
