Comprar datos historicos

Mensajepor Dalamar » 07 Mar 2015 06:45

Dos fuentes de pago interesantes son:

http://www.premiumdata.net/
https://www.quandl.com

Alguna otra recomendacion? En general busco datos de fin de dia, que tengan calidad, splits, dividendos, fundamentales, datos macro, opciones etc... No suelo ir a mas granuralidad que el diario pero cuanta mas a mejor precio, mejor!

Por supuesto entre varios podemos repartir costes.

Una fuente interesante gratuita: (Para advance/Decline)

http://unicorn.us.com/advdec/

Yahoo
Volumes, new highs, and new lows seem consistently wrong for NYSE and AMEX, OK for NASDAQ. All other data looks OK. The page always displays the current date and time, not the date associated with the data.

BigCharts
All data OK except for volumes, which are occasionally reported as negative numbers, so it's hard to trust when they aren't negative.

eTrade
Pretty good data source, although new highs and new lows aren't reported. No longer used here, requires customer login.

DailyStocks
The numbers reported here used to be obtained from barchart.com, with different numbers from Yahoo's but exhibiting the same problems with volume data, new highs, and new lows. They now appear to use data from NASDAQ directly, which we already get.

Financial_Post
Seems to be OK for everything except NASDAQ data, for which unrealistically low values are reported.

MarketVolume
Seems to report unrealistic unchanged issues for all markets, and exhibits similar problems as Yahoo with volume values for NYSE and AMEX. This source often reports values at the extreme end of the range of values reported by other sources. We have dropped this source for that reason, about the same time their data became subscription-only.

NASDAQ
This is the official NASDAQ source, so it's likely reliable for NASDAQ data. It seems to report reasonable values for NYSE and AMEX also.

SmithBarney
If you round the Wall Street Journal values to the nearest 1000, you get results identical to SmithBarney's. Assuming the WSJ reports "correct" values, we count SmithBarney twice to bias the median somewhat. Unfortunately, although data for Monday through Thursday are posted in the afternoon, SmithBarney sometimes waits until Monday to post Friday's data.

Wall_Street_Journal
This source is what we consider most correct, and, like SmithBarney, rarely (if ever) shows outlier values.
