I'm searching for a reliable trading company which exposes a web service for live trade.
Basically I'm interested in:
opening an account (you know, minimum everything for a start - minimum account value
for opening, minimum commissions, etc.) and getting credentials.
Through the web service, provide my credentials and connecting to the server.
Through the web service executing trade operations (mainly buy/sell level 1 stocks under
NASDAQ/NYSE).
Does anyone familiar with such a service and can recommend it?
Cheers
There are a bunch of online brokers that meet the criteria you shared in your comment. An example of a widely used API by retail traders is Interactive Brokers. You can also take a look at Trading Technologies which is more sophisticated in my opinion and have better support. Then there is also TD AmeriTrade. You can also use standard market protocols like FIX to write an execution connector through a FIX Engine. Many brokers support FIX, an example is Goldman Sach's electronic trading platform.
Secondly, from your comment it seems like you are sort of in the testing phase. I encourage you to take a look at some retail trading platforms that are not brokers perse, but allow you to connect to multiple brokers and data feeds. Take a look at NinjaTrader, OpenQuant to name a couple.

I'm trying to choose one of forgerock identity management solution (openAM, openIDM) and wso2 identity server for implementing Identity and Access Management solution.
I'm interested in using following features:
Single Sign-On (SSO)
Policy based access control
Managing user identities
Connecting to central repository like Active Directory, OpenLdap, Oracle Internet Directory etc.
Etc..
Both open source products looks viable. I'm interested in having all of the above features along with good API to implement these features, along with active community support.
Which one would be the best amongst two ?
Thanks.
I am an architect from WSO2 - mostly leading WSO2 Identity Server. I am trying to be not bias as much as possible :-)
Both products bring you a comprehensive Identity Management platform - having support for SAML2, OpenID, XACML 3.0, OAuth 2.0, SCIM, WS-Security standards.
Few unique features that I would like to highlight on WSO2 Identity Server are...
Decentralized Federated SAML2 IdPs (http://blog.facilelogin.com/2012/08/security-patterns-decentralized.html)
Distributed XACML PDPs
User friendly XACML PAP wizard
High scalability (We have a middle-east customer using WSO2 IS over an user base of 4 million for OpenID support.)
Cassandra based User Store ( To be used over 800 Million user base by one of our production customers)
Light-weight and Very low memory footprint. The stripped down version of WSO2 IS can be started with 64MB Heap Size and the standard versions runs with 96MB Heap.
Highly extensible. The architecture behind WSO2 IS is highly extensible. You can easily plugin your authenticators, user store, etc...
Support for multi-tenancy.
Suport for multiple user stores (AD, LDAP, JDBC)
Interoperability.
Part of a proven SOA product platform provided by WSO2.
Also, we are planning to add support for OpenID Connect this year with a set of improved Identity Management capabilities.
You can also read more about WSO2 Identity Server from http://blog.facilelogin.com/2012/08/wso2-identity-server-flexible.html
You will not get an unbiased answer from me for your question :-) "Which one would be the best amongst two ?". You will aso get answers from Forgerock and other folks here. Best would be to evaluate and decide.
I'm a product manager at ForgeRock, but not for the products you're mentioning (OpenAM, OpenIDM).
ForgeRock Open Identity Stack has complete support for all your requirements, based on existing standards such as the ones mentioned by Prabath. It presents a single, common REST API to interact across the platform.
It's easy to deploy, modular, lightweight and yet highly extensible.
But in my opinion the key point is that it's a proven solution, deployed by hundreds of organizations, with built-in internet scale. The solution has been chosen by telecom service providers, medium and large enterprises for internal or customer facing services.
And I agree with Prabath, now that you've got answers from ForgeRock and WSO2, best would be to evaluate and make your own decision.
Regards.

I am currently evaluating WSO2. It has a more permissive APACHE LICENSING Model and a more friendly management model from my having met with ForgeRock people.
Abdul, please share your findings as I am looking at both as well. We implemented OpenSSO in production a couple years ago just prior to its transition to OpenAM. It was an excellent product with thought leadership and decent execution. Unfortunately the pending transition to OpenAM was too unnerving for some of us and we switched to another product at great, unnecessary cost and continue to look over our shoulder. Some downsides at the time were ability to migrate policy through lanes from dev-test-stage-prod, keeping configurations in sync, and issue resolution. Also, fine-grained policy was very new. So my info is a bit dated and I know they have matured since then.
Just starting with WSO2. It has strong thought leadership and good execution with several platforms per other reviews. Their base architecture looks solid and it's allowing them to create and consume/improve open source technology very quickly into integrated, commercially supported solutions.
I am trying to prototype a system that will display a list of choices to a user, and allow them to place an order for the one they select (an over simplification of the prototype, but sufficient to get to the point). I have the users credit card number, billing and shipping addresses, and other contact information, but I can't find any web services that will let me actually purchase something with this information to complete the prototype. I have checked directories such as Programmable Web and Xmethods, but they just seem to point to APIs that let you check for prices and availability, but not actually place an order. Does such a thing exist, or is there some reason (such as security) that I am missing, that prevents such a service from being offered?
The most important thing about online shopping is the security of transmitted information (e.g. credit card data). So the ideal case is to transmit these information directly to the related bank's (issuer of the credit card) payment services, rather than passing it via other service providers. This is what 3-D Secure does.
So when you use a common API this means putting an extra broker between, and passing the secure information to this party which increases vulnerability. Since such a broker cannot use 3-D secure (since it is not the merchant so not possible to make an agreement with the banks) and it should pass the information to online shopping site.
Moreover, an online shoping site can block traffic coming from such an intermediary webservice at any time if you do not make an obligatory agreement and making agreements for each online merchant is practically not very possible.
There is no such free API available the simple reason behind that information like credit card is very secure and confidential and there will security threat on free API's.
here is list of best 10 online payment system
http://sixrevisions.com/tools/online-payment-systems/
and this one who providing live demo
http://www.fastcharge.com/
I think it is possible though I don't know in depth information. I think this is what you see. In next steps you will be redirected to payment gateway of the bank and then you can complete the transactions just by answering some security questions. I think this is a service you should obtain from the bank. And I haven't seen any universal API that can perform the task you have mentioned.

Sorry for the very involved question, but this is something I've been researching for a while now and it is really frustrating me. I feel like in today's age we have a million and one ways to implement services tat are cross-platform (SOAP) and easy to build (thanks to .NET, java, and other frameworks). However, these technologies have been in the community for 5-10 years, but we are (or at least I am) constantly plagued with the same issues:
Identification (Tracking services) - UDDI; e.g., had to remind a co-worker the 3 times this month where a service is at, despite the fact there is a wiki that discusses the service and a PDF version of the same documentation that lives in a repository where we keep our service docs.
Scalability - Out of the box clustering; As organizations, we spend a lot of money on paying our admins just to watch the utilization of our services and make decisions like, does this service need more RAM, more CPU, more interfaces? How do I load balance this?
Monitoring - error logging, etc; I can't count how many times I have to set up tracing on services in order to see why a bug is happening that only seems to affect one customer, or have to code logic into the service to serialize exceptions, log exceptions to dbs, fail gracefully, etc.
Deployment - easy to deploy; none of this deploying DLLs to 5 load balanced servers
Each one of these problems requires some type of custom solution implemented by the organization. Documentation and UDDIs for #1. Virtualization and load balancing hardware / software for #2. Tracing, writing exceptions to databases / logs, etc for #3. Custom deployment software for #4. I work for a mid-sized organization. I can't even imagine how a company the size of Sun, Google, or Microsoft would tackle these dilemmas.
Maybe my vision is unrealistic, but I dream of having a Framework per se that lives on top of a server cluster that manages all of the above. I was ecstatic to read about Microsoft's AppFabric since it really seems to extend some of the functionality of BizTalk to WCF service implementors: Caching, Hosting, Monitoring, etc. However, from what I've seen, I still don't feel it lives up to my dream for an all-in-one solution that assists the developer and organization in writing services that are scaled across clusters easily, deployed into the cluster easily, and identifiable, possibly even version-able.
So, I don't mean this post to be about my dream. I do actually have a question. For starters, is my dream / want completely unrealistic? Furthermore, what solutions are there available that attempt to solve these problems without confining us to a new and more proprietary way (BizTalk) of developing services? An lastly, in concern to a complete SOA / ESB solution, where do we see the most potential in the market right now or in the future?
I think that you are talking about different kinds of problems here.
1). Developers who don't read documentation. This is an endemic problem, not limited to SOA - just look at some questions on StackOverflow. At least the developer is asking you whether there is a service, rather then just duplicating logic in their own code. I don't see any technical solution to these kinds of problems, you've already provided good registries and documentation, but some developers prefer to talk to people. Maybe, even, this is actually a good thing - human interaction has value above the technical content of the interaction. Or maybe, you're too nice: "No, I won't answer that question, look it up."
2). Scaling. There are technologies addressing this issue. (Disclaimer I work for IBM, who sell some, so I'll reference these - I'm not intending to imply that IBM are the only vendor with solutions in this space.) There are products such as this that can provision a new machine, install a software stack and add it to a cluster to address workload changes. Then at a finer grained level of control in the Java EE world the Application Server can dynamically shape traffic and adjust clusters. See WebSphere Virtual Enterprise
3). Monitoring. I don't "get" what you expect here. In all likelyhood such tricky bugs will require application level trace. For some problems such as finding memory leaks and performance bottlenecks there are very good tools, at least in the Java EE world.
4). I can't speak to the .Net world, but I'd say that Java EE app servers do a reasonable job of deploying the apps across clusters smoothly, and in the cases where we use JNI and need DLLs deploying then we can use products such as the Tivoli stack I mention to manage this.
So, in summary, I do think that vendors are trying to address these issues. And I don't think your life would be simpler without SOA. Imagine instead the same problems applied to myriad separate, independent applications.
Here's my two cents.
I've been a developer at a company that used SOA incorrectly. The worst solution they implemented was field level validation of form elements on a desktop app using SOA. To perform acceptably these require very low latency. A 2-4 second wait to change to a new field gets old fast. The service ran over the network on a biztalk server. Everyone hated it.
If you're going to do this you really need to spend a lot of time dealing with network latency, service failure, timing, and timeout issues.
Don't get carried away and think SOA is the solution to every problem. Used at a high level it's great, used at a low level it makes your applications fragile, slow, and impossible to debug.
If you talk to IBM or one of the big SOA vendors, they got a products that cover each scenario.
Identification (Tracking services) - UDDI; e.g., had to remind a co-worker the 3 times this month where a service is at, despite the fact there is a wiki that discusses the service and a PDF version of the same documentation that lives in a repository where we keep our service docs.
Registry and Repository server. Nice thing is that it does governance (promotion, demotion, versioning, approval) and your ESB typically does a "lookup" for the latest and greatest against the register server.
Scalability - Out of the box clustering; As organizations, we spend a lot of money on paying our admins just to watch the utilization of our services and make decisions like, does this service need more RAM, more CPU, more interfaces? How do I load balance this?
Transaction monitoring software like IBM Tivoli Composite Application Manager for SOA. Basically, it tracks things from a horizontal point of view and to see if there is a service disruption from a end user/end app point of view.
As far as your clustering.... you have to pick good middleware and architecture. Personally speaking, get stuff that is "cloud" ready. App Servers with NoSQL connected by MOM.
Monitoring - error logging, etc; I can't count how many times I have to set up tracing on services in order to see why a bug is happening that only seems to affect one customer, or have to code logic into the service to serialize exceptions, log exceptions to dbs, fail gracefully, etc.
Enterprise standards for your developers and for your vendors. Integration of all business and system events into a single dashboard. (Most companies spilt them). This is done already at most enterprise shops.
Deployment - easy to deploy; none of this deploying DLLs to 5 load balanced servers
Ahh.. Microsoft IIS Web Deployment Tool 2.0. You can sync 100s of MS servers by just updating the master. It's really easy.
Web services and web APIs have managed to increase the accessibility of the information stored and catalogued on the internet. They have also opened up a vast array of enterprise power functionality for smaller thin client applications.
By taping into these services developers can provide functionality that would have taken them months perhaps years to set up. They can combine them into single applications that make life generally easier for its users.
Whether displaying information about the music being played, finding items of interest in the locale of the user or just simply tweeting and blogging from the same application - the possibilities are growing everyday.
I want to know about the most interesting or useful services that are out there, especially ones that most of us may not have heard about yet. Do you maintain an API or service? or do you have a clever mash up that provides even more benefits than the originals?
YQL - Yahoo provide a tool that lets you query many different API's across the web, even for sites that don't provide an API as such.
From the site:
The Yahoo! Query Language is an
expressive SQL-like language that lets
you query, filter, and join data
across Web services.
...
With YQL, developers can access and
shape data across the Internet through
one simple language, eliminating the
need to learn how to call different
APIs.
The World Bank API is pretty cool. Google uses it in search results. My favourite implementations are the cartograms at worldmapper.
(source: worldmapper.org)
It's very niche, but I happen to think the OpenCongress API is amazing.
Less niche: Google Translate has an API which will guess the language of something. You'd be AMAZED how frequently this comes in handy (even though it's not as tweakable as you'd like and is not trained on small samples).
I was just about to have a stab at using the SoundCloud API
I know many people who already use for sharing their musical masterpieces and its a pretty good site. Hopefully the api will be as well!
I like the RESTful API for weather.com. It's free and very useful for the new age of location-aware apps: https://registration.weather.com/ursa/xmloap/step1
It does require registration, but they don't spam you or anything - it's just to provide you a key to use the API.
Ah yes - here's another one I've been meaning to check out but haven't tried yet
The BBC offer a bunch of apis/feeds that look very promising
http://ideas.welcomebackstage.com/data
They include apis for accessing schedule data for both TV and Radio listings along with all kinds of news searches. It even looks like they'll be offering some sort of geo-location service soon so it will be interesting to see what that has to offer
Another interesting one for liberal brits! ;)
The Guardian news paper have their own api
http://www.guardian.co.uk/open-platform
MuiscBrainz
Excellent service for music mashups.
Not so many knows that Last.FM initial database was scraped from this service.
The United States Postal Service offers a web service that does address standardization. Quite useful in reducing clutter and cleaning data before it gets put into your database.
Currently using SAS as measurement engine and Business Objects as display layer. Looking to develop a new, faster, slicker solution. Has anyone developed or purchased a campaign measurement reporting system? This solution should measure everything from email stats, web stats, customer activity, lift, ROI, etc.
Ok.. I'm researching and finding nada... We are working with a team from India and they want to re-write everything from scratch.. Any solutions out there at all?
If you are already using SAS, have you looked at their Marketing Automation software?
Update:
Just saw a press release from SAS about a new "Software as a Service" Campaign Management solution. Might be worth checking out for this.
When I was a consultant, we either rolled our own or used SAS (or a combination of the two).
Another vote for roll your own, it's mad that this area is so under served. The expense of building your own solution from the ground up, and the hassle of managing a remote team makes me think you may get further by integrating some existing tools.
Google Analytics for web usage has an API, there are many web log tools, you then need to bolt in the customer figures from your end of things.
I really doubt you could do much better than SAS in this area. Especially if you pick up some of thier specialist packages.
You could have a look at R which is a pretty slick open source statistics package. Unfortunately its not used very much for marketing; most of the examples and freely available code is geared towards biochemistry, genetics etc.
