Community.Providers is a new, open source library of data providers developed by the Wealth-Lab user community.

The initial release contains a static provider for historical Google Finance data. You can use its source code available for download as an example for building your own data providers.

Excellent! Thanks a lot for this one, Eugene. I was in the process of reverse engineering the MQS provider, but this simpler and just saved me a lot of time.

These initiatives are very much appreciated.

FreeStockChart (http://www.freestockcharts.com/platform/v1 )as intraday/EOD data provider

This provider (in free version ) allows downloading 500 data points in all time frames (1 minute to years) for whole universe of symbols ( 500 data point limit is maintained in paid version for intraday but not for EOD (which is unlimited, though their is a way to obtain the EOD history beyond 500 data points for free). Their T-series indicators allows monitoring AD line, U/D Volume and many other "Internals" type reads on intraday basis.

Downloader is 2nd button on the right of Settings ( as seenn on opened chart page).

I wonder if it is possible to incorporate this provider in WL.

Thank you for your suggestion. Unfortunately, 500 data points is not something to consider. Especially when it requires an extra step of decompiling the SilverLight application behind their price feed. Any given provider from our showcase has more. As limited as it is, even Google Finance intraday data offers 5K+ data points for 1-min and ~4K+ for 5-min. The sentiment indicators can be created through the multitude of built-in and additional IndexDefinitions using Fidelity intraday data.

QUOTE:

Disregarding this provider purely on this ground is bit naive, IMHO.

First, the vendor have a large customer base who make use of these 500 points in making day to day decisions.
Second, 500 data point limit (at least for EOD data) can be overcome rather easily.
Third, if you start collecting intraday data, within few months you will have tones of data in your hand.

Having spent tens of (if not hundreds) of hours in trying to produce sentiment indicators using intraday data and WL, I can eliminate this option in a second. Try creating A/D and U/D volume line (using Index lab) for 500 stocks in SP500 on 5 min bars, you will know what I mean.

Sorry, not good points to justify the investment of developer's time and effort into a crippled data kludge.

But if 500 bars of downloadable data aren't stopping you, here's a workaround to your I-L index update speed concern. Impose a similar limitation on the accumulated Fidelity intraday data by backing up your FidelityStaticProvider folder first, then truncating all bars in your S&P 500 DataSet before a selected date using the Data Tool. Try creating your index in I-L, and then restore the static data from backup. If you have further questions, feel free to raise a forum thread (as this one's dedicated to making MS123 data provider announcements).

#49
MS123 Data Providers, August 2016:

* BBFree provider has been taken down due to demise of the free data feed that once powered it
* Quandl provider: added support for CBOE/VVIX

NOTE! Important update to Yahoo provider:

As Yahoo! has recently started adjusting stock volume for splits, there would be discrepancies between your cached historical volume data when a new split is processed. Therefore an important update is made to the Yahoo! provider 2016.09 which we recommend its every user to apply. If split adjustment is not activated in provider's settings, Wealth-Lab will reverse adjust the cached volume. It is recommended that Y! data users refresh their cached histories which is easy to do using the Data Tool's "Remove all data" feature and then updating the data the usual way.

+ Quandl provider: support for ECRI index data
+ IQFeed: automatically capitalizes typed symbol names in New DataSet Wizard

+ Yahoo: During this Summer, the order of columns in Yahoo data changed back and forth. One day this broke v2017.06 the next week 2017.07 and so on. We attempt to fix it in v2017.08 by adding detection of the order of columns. UPDATE 08/03/2017: It seems that Yahoo Finance's behavior is to change the order of fields periodically to break automatic downloaders.
