A while back I was approached to build a user interface for a web-based Bitcoin lottery. That client moved on to a different project, so I was left with what I think is a pretty snazzy front end ready to be bolted to a back end. So I went ahead and created the back-end.    I am reaching out to try and find 10 people or so willing to test out the app. If you are interested in help test, send me a PM. I know there are dozens of others here looking for testers also, so I am hoping that the fact that I am going to fund the pool is a little incentive. I won't open it until I can find enough people. As for the future of the app, I am still undecided. I am open to discussing sale of the application if someone happens to be interested. - Single page web application. - Log-in only requires a valid Bitcoin address. - Laravel backend. - MySql database. - No sensitive data stored on site. ( no passwords or private keys) I can arrange a demo for those interested. Just send me a PM. Other then the stuff that comes with Laravel, the game code and account management code is mine. |

It is not cumulative... if you hit more than one time a second, you can be banned at any point. Exchanges have to limit traffic or they will get DOSed out of business.

I guess most exchanges will ban you, if you fetch prices every second? Bitstamp will ban you if hit their server more than once a second, unless you can convince them to whitelist your IP. |

I do professional design and development, I would be happy to discuss your needs via PM if you wish. I have board references. Otherwise there seems to be plenty of people on the forum with the skills that you need. You might want to start your own thread though so your needs do not get buried in this thread.

So here is the interesting thing.... when I initially tested the code, I wrapped it in a jquery on-ready, and it didn't work in any browser. I redid the code without the on-ready, and now it works in Chrome and Firefox, but not IE (v 11.0.9600.16476). lol... strange. Using the following code, IE displays 'error, no transport'. <!DOCTYPE html>
<html>
<head>
<title></title>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
</head>
<body>
<div id="BTCPrice" style="height:40px;margin:auto;position:absolute;top:-20;left:0;bottom:0;right:0" /></div>
<script>
$.getJSON("https://api.bitcoinaverage.com/ticker/global/USD/", function(data){
$("#BTCPrice").text(data["last"].toFixed(2));
}).fail(function( dat, textStatus, error ) {
var err = textStatus + ", " + error;
alert(err);
});
</script>
</body>
</html>
I cannot figure out why an on-ready should make a difference, or what about this code makes IE unhappy, but the code does indeed work on at least two browsers. |

Interesting. It is behaving exactly as I expect, which is to not allow the request. Let me ask a question. I understand that bitcoinaverage will explicitly allow requests from anywhere, but I don't understand how that translates into the browser accepting that data. It seems to me that if it were the case that all one needed do to allow cross-site scripting is to have the other site set the origin flag. In my head, whet the server allows has nothing to do with what the browser allows. Now I am going to have to revisit some docs, because your example goes counter to my understanding, and it doesn't work in any browser. I know a couple of different ways to circumvent this issue, but not like you did. So here is to me learning something new......  |

Yes. |

@talkcrypto, That example should not work for you due to do browser security issues ( and it doesn't work for me either). That represents a cross site scripting request since the domain is not the same as yours. The code is actually retrieving the values, but it is just discarding them. Due to browser security restrictions, most "Ajax" requests are subject to the same origin policy; the request can not successfully retrieve data from a different domain, subdomain, port, or protocol.
Script and JSONP requests are not subject to the same origin policy restrictions.
http://api.jquery.com/jQuery.getJSON/If you are trying to run your code from your localhost, then this will and should fail. |

You also need an element with an id of 'price' somewhere in your HTML. There are a ton of ways to do this, but it can be something as simple as: <div>Current BTC Price:<span id="price"></span></div> Is that what you are asking? Or is the javascript not returning any information? With the exception of the jquery import, you really only need two things; some javascript, and a little html, and that is really it. If the data is not coming back correctly, then something else is going on. I don't see anything wrong with your code though. I can help, I just need to know where you need it. |

Didn't Google. Discovered the quote via Iron Maiden, and was drawn to Lovecraft. Yeah, I'm a little older than the rest of the crowd. Sorry BlackMarketKarma; wasn't trying to hijack your thread. I just recognized a bit of culture, so I had to ask. |

And with strange aeons even death may die. Lovecraft fan, or Iron Maiden fan? |

Can you open the file with a text editor and see if your key is in there. Multibit only imports plain text files as far as I know, and JSON is a text representation of a javascript object, so maybe that is all you need to do.

I am happy to announce Modobot.com, a simple web-based trading bot for Bitcoins. I designed the bot for me, namely someone that does not have sophisticated trading know-how, but would still like to participate in automated trading. Modobot uses a simple buy-low, sell-high strategy that is easy to understand. The bot can be configured to create automatic transactions based on margin, or can be configured to make one-off limit orders. Sign-ups are free. Live accounts will be accepted on a rolling basis. Trading on live accounts will be limited to 1BTC per transaction. Membership will require a valid email for account recovery and validation. The support forum will require an email validation also. I apologize. If I do otherwise I am at the mercy of spammers. I also added a public test account: name: ModoBot pass: modobot_demo The bot is locked in testing mode. Other than that it is completely functional.  | Modobot.Com |Features: - Sandbox mode for testing trading strategy and bot functionality. - Calculator to check spreads. - Record of starting balances in USD and BTC. - Rolling status log. - Bot transaction history. How it works: - A valid Bitstamp account is required. - With a valid account, create an API key, and configure your account to allow Modobot to initiate transactions. - Upload API key and credentials to Modobot.com. - Configure bot for live trading. - A background process periodically grabs data from Bitstamp and processes each of the bots. Security: - Modobot does not store member passwords. - Bitstamp Api credentials are hashed on disk. - Api access can be controlled by IP address, so only the Modobot server can access the account. - No data on the Modobot site can be used to leverage unlimited access to your Bitstamp account. Privacy - Modobot does not store or require any personally identifiable information. There is some logging in place for security purposes. - Emails addresses are stored for account recovery purposes, and for any site related announcements. | Modobot.Com Support | |

I started working on a mobile companion to the website. Eventually it will be able to monitor one's bot from a mobile device, but right now it is just a simple ticker with Bitstamp and BTCe, and includes conversion for USD, AUD, GBP, and EUR. It updates every 10 seconds. I am trying to work out a theme for the app, and this is the result so far.  Does anybody have any strong thoughts regarding the design so far? |

I was recently contracted to create a simple web app to facilitate cash-for-bitcoin/bitcoin-for-cash transactions. Basically the app works like this: - On the website, the user chooses the type of transaction, Western Union to BTC, MoneyPak to BTC, etc. - Depending on the selection, instructions are presented to the user on how to send Western Union, or how to send Money Pak, along with the necessary bank account information. - Once the user deposits the cash, the user then completes a validation form and submits it. - On receipt of the information, the seller then deposits Bitcoins into the buyer's account. The app is a single page web app with a tiny amount of PHP on the back end. There is no database component. All notifications and information submitted into the website are emailed to the appropriate recipients. Price is pulled from Bitstamp. With minimal modifications, the code can be up and running in minutes. It is in dire need of someone with an eye for graphics. The original client made a partial payment, but has since gone unreachable. If anyone is interested in purchasing the now completed software, please PM me. I have the final working version that can be viewed. Escrow only. Min  |
