Downloading fundamental data extra from Yahoo Finance

Hi Tomasz,

I think there may be a way to get what you need in less than 1/100th the time.
I've been using this method to get yahoo fundamentals data it allows you to bypass the parsing of java script etc.

The result is in the form of JSON response instead of HTML and is easily parsed.

Example query:,recommendationTrend,financialData,earningsHistory,earningsTrend,industryTrend&

Replace or add modules to what you need; can add all modules but sill still be fast.

# list of Modules for query:
#     [
#        'assetProfile',
#        'summaryProfile',

#        'summaryDetail',
#        'esgScores',
#        'price',
#        'incomeStatementHistory',
#        'incomeStatementHistoryQuarterly',
#        'balanceSheetHistory',
#        'balanceSheetHistoryQuarterly',
#        'cashflowStatementHistory',
#        'cashflowStatementHistoryQuarterly',
#        'defaultKeyStatistics',
#        'financialData',
#        'calendarEvents',
#        'secFilings',
#       'recommendationTrend',
#        'upgradeDowngradeHistory',
#        'institutionOwnership',
#        'fundOwnership',
#        'majorDirectHolders',
#        'majorHoldersBreakdown',
#        'insiderTransactions',
#        'insiderHolders',
#        'netSharePurchaseActivity',
#        'earnings',
#        'earningsHistory',
#        'earningsTrend',
#        'industryTrend',
#        'indexTrend',
#        'sectorTrend']

Thanks, it was my plan to eventually remove all "built-in" sources at all and leave only user-definable ones. That way you could quickly change the way how data are retrieved if data source changes their layout and/or API.
So, if that proves to be complete replacement for old method, then built-in fundamental downloader will be removed and user-definable data source will be added for that.

I am sorry but I do not understand how I can solve my problem to download fundamental data of more than 5000 listed stocks. Explain me in a simple way. How can I use that program code inserted above? Many thank for a clarification. Fredrick

Hi Federico,

This will require a change to AmiQuote to use the new method of fetching Yahoo data. I don't think from the above that it will be implemented. Alternatively if you're techsavvy, you can write a program in JAVA, Python, etc. and fetch the fundamental data for a list of stocks and load it into the AmiBroker DB.

No, it does not require change in AmiQuote because AmiQuote 4.10 features user-definable data sources WITH Javascript parser. So you can define your own data source that will use URLs provided in this thread.

If I have well understood, you are telling me that in the new release of Amiquote, I will be able to define the fundamental data that I am willing to download for all the stocks I am used to work with. Then I will download these fundamental data quickly (for instance 2-3 hours). Is this correct? I suggest you to insert all the fundamental data already present in the last version of Amiquote. A trader may choose to download them all or only a part of them. I ask you for a confirmation of my reasoning. Thanks.

Yes, you can DEFINE any data source in AmiQuote 4.10.
I took time to prepare a new Yahoo Fundamental user-definable data source.

The ready-to-use file is here:
[OBSOLETE - Removed. Download AmiQuote 4.14 instead]

You can download it, save to disk, then use Data Sources->Import menu to import it into AmiQuote. Once you do that a new data source will appear at the end of the list called "Yahoo Fundamental Extra New".
Now you can use it instead of old Yahoo Fundamental.



Thank you @Tomasz for taking the time to do that!

I just tried to run this and kept getting this window to pop up and had to shut it down....

I just tried on WL DJI with no problems

@MCassICT Again and again, ANY error displayed by AMiQuote is not coming from AmiQuote but from YAHOO (or any other provider). In case of error returned by YAHOO AmiQuote just passes it "as is" and displays to the user. One cannot do anything if error occurs on server side except REMOVING symbols that are NOT present on YAHOO.

As for Javascript error, it is because Yahoo for that particular symbol misses several fields and script attempts to read certain object by name and found none.

I have modified the script to handle such situation:
[OBSOLETE - Removed. Download AmiQuote 4.13 instead]


Thank you Mr. Thomazs for the update, this new menu is very helpful. Gbu

Sorry, I automatically typed Mr. Tomasz name

Please help add ONE_YEAR_TARGET to csv and "FD/targetMeanPrice" to field.
Is there a way to disable the pop-up windows? (please ignore this. The later script has already fixed the problem.)

Thank You Tomasz,,

but now I need to use "Symbol Translation" for my symbols
how can I do that now?

all my symbols are same but I have to add at the end of any symbol ====> .SR

Very helpful @Tomasz .....thank you

@sahir001, I suggest to take a look at this article.

In any case, before attempting this operation, be sure to have a BACKUP copy of your database.
