no data for today. any one also facing this issue.
any reason

You mean Yahoo data? Will need to check it

 

[traderniftybull]

yes, yahoo data
vaise, PyD downloads only Yahoo data.

Yes. IEOD as well as EOD data for 29/03 for IN Equities is not available on Yahoo site/ servers. In technospeak its called a Data Holiday!!!

Hopefully, whatever may the reason be for it (whether technical/ licensing agreement etc), will get sorted out over the weekend

@rmike I was testing this wonderful utility and was wondering if you can provide an input-ouput format capability for the scrips.

Maybe TickerList.txt can have a special separator as an identifier
So currently its one symbol per line can be
^NSEI=NIFTY
Then the downloaded files will be named and formatted accordingly.

I think in most cases it just works as the suffix exchange is dropped but any other suggestions for this one?
But capability of renaming add per user choice would make it free of lot of things like having secondary ticker etc

Thank you

If you are using amibroker, the issue can be easily addressed by Symbol Merge and assigning of Alias. By doing this, the data from both sources (Yahoo (IEOD) and the one you are using as RT feed) will be assigned to the same ticker! You can look up the 'how to' for both procedures in amibroker help

Am sure that a workaround on these lines would also likely exist for other TA platform(s) too which you may happen to be using. You can query the support of these platforms for the same!

Unlike Investing dot com wherein the site ticker nomenclature is vastly different and a facility for user renaming is essentially required, Yahoo follows similar ticker symbology as of the exchange barring the spot indices (which are not trading tickers in any case) and a couple odd exceptions. Hence introducing the facility of user renaming in PyD would unnecessarily waste precious millisecs as the logic loop of query-read-transform-write would have to necessarily repeat (needlessly) for each ticker! Since the utility is aimed to be a lean bare bones tool for backfilling intraday data on the fly even during market hours, even a small inefficiency of the process would lead to undesirable incremental ramifications!

Thank you, I understand. It makes sense.

Well ................. All seems to be well with Yahoo on the first day of the NEW financial year .................... AND PyD is back to business, as usual!!!

 

[traderniftybull]

hmmm
but still missing data for 29.3.19

Hey mike, the PY downloader is working at top gear.
Can you link it to open an excel file after downloading is complete? And probably run a macro embedded

 

[rmike]

This can be done by using windows .bat files without the need to modify utility code

Plenty of info on this is freely available on the net. Have a look! Its not all that difficult! You ought to be able to implement this with just a few commands

hi mike,
thanks for your kind effort..your utility working wonderfully..can you pls implement 300 stock limit just like previous pydownloader.. it will avoid manual replacing of file and at the same time wont be subject to abuse.
