I want to use the IB Api, but cannot figure our how the request a complete symbol list and information.
In the Documentation i found: reqScannerParameters() - but it is not clear how to get a list for example of nasdaq stocks ?
Is there a better way ?
As far as I am aware IB does not offer a symbol list. But the good news is it is easy and free to get elsewhere. Eoddata.com is a good source of it and you can download them, or automate it rather easily.
Go here and just click the download link at the top right of the table: EodData Symbol List
Not sure what language your using for the IB API but I have simple tutorial in C# that covers reading the tickers for stocks and options on my website: Get Real-Time Stock Data from the Interactive Brokers API
It is fairly easy to implement a piece of code scraping all stocks symbol from IB's website.
NYSE stocks are available from IB website
Just replace 'nyse' with another exchange's name like nasdaq or amex.
If you go to their products listing you can drill down to find lists of the entire universe of products (in case the link expires, I just googled "IB Product Listings")
https://www.interactivebrokers.com/en/index.php?f=1563
For example, I went to their NYSE product and scrolled through a few pages to find everything I needed. Here's an example of what I found
https://www.interactivebrokers.com/en/index.php?f=2222&exch=amex&showcategories=STK&p=&cc=&limit=100&page=3

I'm helping develop an online ordering process for a local business, and they are offering food delivery to their location from specific partnered restaurants. The problem we're looking to solve is making the experience as smooth as possible for the user, so we're aiming to fill out these specific data fields to make the process smoother. They have QR codes on their tables, that link directly to their websites ordering page, from there the user can select from a few local restaurants, and are linked to their online ChowNow menus.
Does anyone have any experience using ChowNow, and knows if there is any way to pass off specific delivery instructions to ChowNow, specifically an address, from the link provided to the users from the QR code on their table?
We haven't found anything too helpful on this problem from ChowNow's official documentation or support. There are alternate ways that we have in mind to solve this problem if need be, but this is the desired solution from the client, and we would like to have stick with this method if possible.
I'm using the Rally SDK 2 to manipulate user stories from Javascript in a "Custom HTML" application.
I can query a story and retrieve its attributes.
I can update some of the attributes, like the Name of the Iteration for instance.
How can I add a successor to my story?
If I understand well, I should edit the "/HierarchicalRequirement/.../Successors" of my story, but I don't understand how to do that.
Would someone have an example, please?
Unfortunately, I don't have an exact example you can use, but the successors (or predecessors) are 'collections'. As such, you need to 'add' to the collection. There is an explanation of some of this here: https://docs.ca.com/ca-agile-central/saas/apps/2.1/doc/#!/guide/collections_in_v2
Built into the model for the artefact are routines to handle all the details. If you want more details, then you can download the sdk-debug.js file from the Rally server. To get to it, open up the developer tools in your browser and have a look where a custom app would get the sdk.js file from. The debug variant is formatted for humans to read and a very useful source of how to do things at the low levels. The definition of Rally.data.wsapi.ModelFactory has some good tips.
One of the recommendations I make to people starting out writing custom apps, is to use the developer tools in the browser to watch the network traffic that the Rally UI makes - and then work backwards to code.
I'm doing my final project for a coding school that will be a deep song search app that returns every detail about a song (composer, personnel on the track, lyrics, studio, media uses, images, etc). I'm using React frontend/Rails backend API. I'm new to API's and have tried Discogs and Musicbrainz but find the Mediawiki to be the easiest to traverse. Messing with their sandbox using Query, I feel like I'm getting closer but wondering if anyone with more experience out there could help me get precisely what I need.
I would like a music search to return a list of matches (could be same title but different songs or same title but different recordings). A user can click on the results to see the details. I would like the API to return links and hopefully images (album cover, etc). Does anyone know the best way to go about this?
I've also tried using the Ruby Gem wrapper Mediawikitory https://github.com/molybdenum-99/mediawiktory. I like the clean interface but can't quite find the right parameters.
The closest I've come to what I'm looking for in the Mediawiki sandbox is an example like this for the All Star (Smash Mouth):
https://en.wikipedia.org//w/api.php?action=query&format=json&prop=&list=search&continue=-%7C%7C&srsearch=star%20(song)&srlimit=5&sroffset=15&srqiprofile=engine_autoselect&srwhat=text&srinfo=totalhits%7Csuggestion%7Crewrittenquery&srinterwiki=1
This gives a list of songs (I'll have to concatenate '(song)' in every search unless there's a specific category parameter I don't know about).
So with further research I was able to drill down to specific song searches (and this will work for any thing this specific). You have to use srsearch and then search option in lists. So an example for a list of songs based on a given title:
https://en.wikipedia.org/w/api.php?action=query&formatversion=2&format=json&prop=info%7Cpageimages&generator=search&inprop=url&piprop=thumbnail%7Cname&gsrsearch=I%20love%20you%20(song)&gsrwhat=text
Make sure you choose version 2 as it gives you a better formatted Object to map over.
The Mediawiki API is very robust. You just have to spend a little time with it. The sandbox is great.
Am trying to create a program that fetches data from yahoo finance all stock data.
I found one rest API that gives me a stock price but I have to pass two parameters ex. if I have to get Apple stock price I have to pass Apple and stock name but I want all stock data so how do I get ??
can anyone help me thanks in advance
Unfortunately there isn't any official source of tickers or method of getting them.
You can use this script link to download tickers but as creator mentioned:
it is not possible to get all the symbols due to limitations set by
Yahoo. About 75%-90% of all symbols are gathered using this script
depending on type.
And it also downloads some no longer existing or inaccessible tickers.
From this site link you can download list of almost all tickers but about 30% of tickers are either in wrong category or aren't working. Checking whether ticker exists is easy because when API returns no data then we can deduce that ticker is incorrect. But checking if category is appropriate is a bit more complicated.
I've filtered tickers from the second site but only ETFs and Mutual Funds, you can find them on my GitHub. Those files contain about 99% of ETFs and Mututal Funds avaiable on Yahoo. I might consider filtering stocks later and then I'll upload them with script too. Be aware that filtering tickers is impossible on one run without for example VPN because Yahoo limits request to about 10k-20k per day and there are about 20k tickers per category and checking each ticker requires 2 requests.
Try with IEX api, it's free, and it provides very complete data, a very simple implementation and a very neat documentation
if yu want AAPL real-time price you just have to request
https://api.iextrading.com/1.0/stock/aapl/price
Here's complete documentation
https://iextrading.com/developer/docs
I was searching for a solution to a similar question for a long time. and at last, I got a solution to my problem.
there's a library in python that does this for you!
All you have to is pass the right symbol for the stock (for ex: the symbol of Infosys is INFY)
Here's the link to the documentation of the library
Dynamic Stock prices :

Historical Stock Data :

I hope this helps! All the best
I've seen sites like this (http://www.tradename.net/) on the web that seem to be nothing more than a collection of news articles pulled in from different places - all seemingly automated... I would like to know how can I create something like this that:
(a) either automatically, one its own pulls data from different news feeds and creates these articles/news-conent, OR
(b) I run a program periodically to update all its content
I am looking for a ready-to-run software / module that I can take and put in either the keywords or links to news feeds and get it to work... I'm not interested in one of those paid template sites.
Another example: http://www.limitedliability.org/
You can just make your own website like that. Just use rss-feeds from topics / newswebsites that you like to show your users. Customize your website like how you want it yourself using one of the scripting languages. It's not very hard to loop through all news flashes in a rss-feed and show them to your users.
You can use PHP
Or .NET
Or Javascript
Ans obviously there are more ways to do this. Just take a good look around and check with what scripting language you feel most comfortable.
Create a script that parses the rss-feeds from the news sites, and only store the ones that you are interested in.
Or just create your own Google News feed and add it to your site. There are free feeds for non-commercial use.
