I have a new site that allows you to write stock trading applications and see how they would perform. Its in beta but I would love feedback.

You need to have examples for the backtester and screener ASAP... I can't even figure out what language these should be written in... are they written in Javascript?

Also, it was difficult to figure out how to create a new application... Put a box around the "Create New" button to make it more obvious that that is a button.

Overall, the concept has merit... You need to make clear that this is a PROGRAMMABLE stock tracking website, since that seems to be the innovation here. Might be something I would use, once it's more polished.

Note that you app somewhat limits users to "programmers who are also stock traders", which could be a smallish niche... The barrier to adoption of your tool are high as well- Steep learning curve. Also, many such folks may not trust you enough to store their trading strategies on your site.

...You're going to have to create a _fantastic_ implementation of your idea before a critical mass of people will spend the time to learn the system- Long way to go.

But I can see what your trying to do and I think there is potential in this direction.

It is javascript...thanks for your feedback

Is the backtester "script" executed server side? Why javascript?

Both screener and backtester are executed client side. Its very opensocial style of development. Also since this is private funded I dont have money for servers on server side.

Also for the non programmers...the applications can be made public so non programmers can use the public of applications.. Also the app developers like in opensocial can throw ads on the screeners.

Could you upload or paste a (complete) example backtest script?

The following code is for a backtester. I created the application on tickmarkt. It checks when an exponential moving average with 5 day lags crosses over the 10 day moving average and will open a trade. You might need a large time period for this to work or you can lower the lag and it will fire off sooner. I have some technical analysis indicators built into the system that I will soon open source as well.

here is some example backtester code:

var hasTrade = false;

function Init() { }

function Tick() { //5-day exponential moving average var ma5=analysis.Technical.ema('AAPL', 1 , 1 , 5 );

//10-day exponential moving average var ma10=analysis.Technical.ema('AAPL', 1 , 1 , 10 );

//invalid time data because of weekend if (ma5.length == 0 || ma10.length == 0) return;

if (ma5[0].value > ma10[0].value) { //open a trade if we dont have one if (hasTrade == false) {

      api.Broker.OpenTrade('AAPL', 
                           100,
               'open trade on cross'); 
     
     hasTrade = true;
   }

} else if (ma5[0].value < ma10[0].value) { //close a trade since we have one if (hasTrade == true) { api.Broker.OpenTrade('AAPL', -1100, 'close trade on cross');

      hasTrade = false;
   }

}

function Destroy() { }

can I email you at any particular address?

Sorry Edit its tickmarkt not tickmark

I'm not a professional stock picker, but I found the interface confusing. After I made an account and logged in I was not sure what I should be doing or where I should go.

I managed to click around and find google, but then accidentally clicked a trade button and now I have an open trade for 3 shares of google at 100.17! I have no idea how that happened or what it means.

Your site is also a bit slow, but I'm assuming that is because you are under provisioned and this is an alpha.

Good luck.

"I found the interface confusing"

That's my experience as well. I'm not sure what the site is trying to do. I had to sign in just to find out.

Care to explain the site for us? I'm not a trader, so I might be missing something.

The site is basically a website where you can write backtesters and screeners and there is a bit of social network/trading thrown in. Screeners and backtesters work on algorithms to actually find and trade stocks. I have traded in the past and always wanted something like this. There are software packages but they are expensive and you need a lot of money for them and the data feeds are expensive as well. My goal is to bring all this information in an easy to use way.

The big part of this site is the backtester and screener. Its basically the place that you can write applications against our data. http://tickmarkt.com/app/documentation tells you the apis for both. Hope this helps a bit.

Please let me know what you think of the site. Its currently in stealth and I wanted to share it with the community.

tried to sign up twice and got a "change you wanted was rejected" message
