Show HN: Guess whether a stock will rise or fall - and get instant feedback
- unclegene 14y agoParse error: syntax error, unexpected T_DOUBLE_ARROW in C:\wamp\www\fakemoneyrealstocks.com\register_popup_complete.php on line 5
- ssanders82 14y agoWhoops, fixed!
- ssanders82 14y agoThis is a re-launch of a web app I made a few years ago. I'm operating on the freemium model: pay a small one-time fee for access to premium features such as trade position size and price/volume indicators. Feedback needed, thanks!
- mikeevans 14y agoThe chart images are broken for me. Also, when I click buy/sell, nothing seems to happen. But when I refresh the page, I seem to have made money! Seems like a fun an addicting idea though.
- ssanders82 14y agoHmm I've gotten a few errors come through with a blank user agent, perhaps that's it? What browser are you on?
- burke 14y agoAfter getting 10 wrong in a row, I've decided to start buying more mutual funds.
- daemon13 14y agoTechnical analysis chart looks cool, i.e. like a real one. What lib did you use for charting? Excellent idea - shall indulge some folks, if you go the app way. Better kill time with this than some MonsterCatJumpingDrawing app...
- ssanders82 14y agoCharting library is Telerik (http://www.telerik.com/products/aspnet-ajax/chart.aspx http://www.telerik.com/products/aspnet-ajax/chart.aspx) - expensive but powerful. Thanks for the kind words.
- daemon13 14y agoYou are welcome :-) What are your plans with it?
- tgrass 14y agoHow far back does your data go?
- ssanders82 14y agoI have data for all US stocks since 2000. At this point I limit the web app to the past few years or so, and only for S&P 100 stocks. I'll eventually open up more data for the premium users.
- tgrass 14y agoIt seems the data is from the last four years...you'd be safe to just buy.
- netvarun 14y agoIts seems like a really cool idea. I have one question: Where do you get all the previous financial data? You scrape from the financial sites? -- Shameless plug: There is a site I recently built which is kinda related. (I just finished it last week. Still doing some testing, but would like to gather some feedback) Its called QuantHunt (http://www.quanthunt.com/ http://www.quanthunt.com/) Basically you write a forex trading bot using a simple API and your progress is tracked in a leaderboard. Real world ticker data is used for the prices. [Invitation code for registration:qKMqNj]
- ssanders82 14y agoThe historical data was free from finance.yahoo.com. I'll check out your link, thanks!
- marcusrobbins 14y agoI'd be interested in getting my hands on the data generated by this app. It would useful in building a stock prediction AI.
- maeon3 14y agoAre you serious about that? If so contact me.
- raldi 14y agoNice. You should post benchmarks comparing the player's return to that of some well-defined AI's, like one which is always an optimist, one that's contrarian, and one that's a monkey throwing darts. It would be a real eye-opener to those who do worse than the monkey.
- user24 14y agoA simple guide to how to read the graphs for a noob like me?
- ssanders82 14y agoThe art of reading stock charts is called technical analysis (http://en.wikipedia.org/wiki/Technical_analysis http://en.wikipedia.org/wiki/Technical_analysis). It's disputed whether it works or not, but it's fun to try!
- Luc 14y agoHere: http://www.amazon.com/Evidence-Based-Technical-Analysis-Scientific-Statistical/dp/0470008741/ http://www.amazon.com/Evidence-Based-Technical-Analysis-Scie... Bottom line (but very controversial among any diverse group of investors): it doesn't work. I always try to steer people away from it if - it's one of those big choices in life (like choosing a good wife or husband) that can have a major impact a few decennia down the line.
- maeon3 14y agoNeat idea, it worked perfectly on the samsung galaxy s2 with android. I did a bunch of trades and lost money on most and got up to the screen to hit the user with the "pay me or go away" screen. On that screen, clicking "close" link makes the entire frame popup blink once, indicating failed click and no action taken. Reloading the page brought me back to the main screen for 14 more trades. Clicked buy now to see if that worked, pondered throwing you the 10 bucks. Paypal says: This recipient is currently unable to receive money.
- ssanders82 14y agoThanks for trying. Paypal shut me down because they think I'm a financial services provider and are asking for all my professional membership licenses :( Ssssh: If you click the paypal button now, I've redirected it to upgrade you for free! I haven't tried this on my Galaxy Nexus so I'm surprised that it worked as well as it did on your phone.
- steve8918 14y agoPretty fun, but not very realistic in the sense that the trade is taken exactly after 10 or 20 days. You don't allow setting stop losses, etc. Chartarcade.com is a really good stock simulator. It's been around for a while, also uses real stock data, and allows you to buy and sell while incrementing on a per-day or per-week basis. It's actually a really good tool for learning how to buy and sell stocks on a swing basis.
- ssanders82 14y agoThanks for the link - that's a very polished tool. My advanced mode lets you step through day-by-day in a similar manner.
- adventureful 14y agoIf you're getting your data free from Yahoo (scraping or API), aren't you limited by their non-commercial use clauses? That is, if you try to make money off of it without buying the data, doesn't that open you up to a huge liability risk? Pretty sure that's stipulated all throughout their service (that you may not use any of their data for commercial purposes without their permission). Acquiring that kind of data for commercial purposes normally costs a lot of money (relatively speaking).
- maeon3 14y agoTried to throw you $10 there bub, but I after I clicked the "paypal" round button to buy, It sent me here: "https://www.paypal.com/us/cgi-bin/webscr?cmd=_flow&SESSION=8WHSr8scea1JaUOz4KUeRFbjkAEI-R4BqQidi1fxlgNi0Bd5uq__yhADmk8&dispatch=50a222a57771920b6a3d7b606239e4d529b525e0b7e69bf0224adecfb0124e9b61f737ba21b081981856b91947e5c600b2b0863f9534cbec https://www.paypal.com/us/cgi-bin/webscr?cmd=_flow&SESSI...

- dnc 14y agoI've just made $2,180,000.0 :) (169 trades). Simple, nice idea. Congrats!
- beej71 14y agoI never recovered from trade one. You should quit your day job. ;-)
- zackmorris 14y agoI also got to almost $2 million after a couple hundred trades, but then just started pushing buy every time and went back down to $100k. I helped my dad get up $40k on etrade in the 4 months just before 9/11, pleaded with him to collect his winnings in August, and then it all trickled away in the weeks afterwards. Stock trading is just a casino where the odds are 2% in your favor each day, but only the rich can play. I think hackers make good traders because of their contrarian nature, and ability to stay cool and read signs that most people are too impatient/impulsive to see.
- daemon13 14y agoSam, you got some cool stuff under your belt [this and prior projects]. You definitely need to make smth out of it!
- cocoflunchy 14y agoIs it really unthinkable to trade for more than 20 days? Does anyone play long-term in this game?
- losethos 14y agothe Bible is full of people begging God to act. You mostly don't hear what happens. Life is a journey. What happens to someone who peeks in their 20's and declines from then on? God says... and that the cloud was taken up in the morning, then they journeyed: whether it was by day or by night that the cloud was taken up, they journeyed. 9:22 Or whether it were two days, or a month, or a year, that the cloud tarried upon the tabernacle, remaining thereon, the children of Israel abode in their tents, and journeyed not: but when it was taken up, they journeyed. 9:23 At the commandment of the LORD they rested in the tents, and at the commandment of the LORD they journeyed: they kept the charge of the LORD, at the commandment of the LORD by the hand of Moses. 10:1 And the LORD spake unto Moses, saying, 10:2 Make thee two trumpets of silver; of a whole piece shalt thou make them: that thou mayest use them for the calling of the assembly, and for the journeying of the camps.
