Free Quotes request

Postby danilo » 28 Jan 2009

Dear Marina,

I have discovered that MC when import data from yahoo doesn't adjust the quotes for dividends or stock splits, if you give a look to the ETF FXI on the 23-Jul-08 the was a 3:1 stock split, in MC for this date is shown a big gap that doesn't make sanse. TS Support should add an option to adjust the data when are imported from the Free quotes.
The logic is the following: every time that the Close is different from AdjClose MC should adjust the data i.e.:

Open = Open * (AdjClose/Close)
High = High * (AdjClose/Close)
Low = Low * (AdjClose/Close)
Close = Close * (AdjClose/Close) = AdjClose

I hope that this fix will be available for the next release.

Regards,
Danilo

if you look at Yahoo's quote, you will see the adjusted price is sent along with the unadjusted price.

MC should be smart enough to read the adjusted quote and give user a choice to select those.

Hi guys,

Regular providers, such as eSignal, for example, provide stocks that are adjusted already.

Locally, it will be possible to adjust stock splits in future versions of MC.

Marina,

It's necessary to adjust even the Open, High and Low. Since the information is available for free during the Yahoo's quote download, the adjustement should automatically performed by MC.

I still hope that the fix will be available for the next release.

Regards,
Danilo

Hi Danilo,

Not being able to perform stock split adjustments in MC is not a bug. We are talking about bugs if a functionality's behavior is different from the intended one. What you are talking about is classified as a feature request.

As for Free Quotes, the sources where the data is pulled up from are limited in so many ways that it doesn't make much sense for us to add functionalities to work with those free sources, especially since real data feeds already provide adjusted stock split data. We regard Free Quotes as a secondary source of data.

Dear Marina,

The new feature could be implemented just inside the FreeQuotes plugin, and to adapt MC to perform the adjustement for Yahoo's quotes, should be necessary to add the folowing 4 lines of code (2 minutes of programming resources):

Open = Open * (AdjClose/Close)
High = High * (AdjClose/Close)
Low = Low * (AdjClose/Close)
Close = AdjClose

Regards,
Danilo

P.S.: IB provides only 1 year of historical quotes, Yahoo much more

Hi Danilo,

Implementing this feature will take much much longer than two minutes. At the moment, we cannot fit it into our development schedule. But it will be implemented in one of MC future versions.

Regards.
