ING DiBa Stock Watchlist Scraper

A script which uses CasperJS and PhantomJS to scrape the contents of a ING DiBa stock watchlist into a CSV file.

Optionally, you can enable prom output in the config file and then it generates a metrics file for Prometheus.

Prerequisites

• create stock watchlist at ING DiBa website
• add some stocks to watchlist

Installation

• install PhantomJS
• git clone https://github.com/mjaschen/ing-diba-stock-scraper.git
• cd ing-diba-stock-scraper
• make install
• edit config.js (fill in login and password values)
• verify/update file permissions of config.js (you may want to remove file permissions for everyone but yourself)

Starting a scrape

• make

The current values of the watchlist will be saved as a CSV file in the data sub-directory.

The script is quite silent with default settings, but it's possible to make it more chatty:

• make CASPERJS_OPTION_LOG_LEVEL="debug" CASPERJS_OPTION_VERBOSE="--verbose"

Example of CSV output

timestamp;id;isin;name;count;quote_watch;quote_current
1472978211;24299486;NL0000235190;Airbus Group;250 St.;57,479 EUR;53,011 EUR

Example of prom output

#HELP stock_price The stock price, either watched or current
#HELP stock_count The number of stocks in the watchlist
#TYPE stock_price gauge
#TYPE stock_count gauge
stock_price{type="current",id="23590133",isin="US88160R1014",name="Tesla",currency="EUR"} 260.82
stock_price{type="watch",id="23590133",isin="US88160R1014",name="Tesla",currency="EUR"} 197.586
stock_count{id="23590133",isin="US88160R1014",name="Tesla"} 1
stock_price{type="current",id="23561025",isin="DE0005089031",name="United Internet",currency="EUR"} 39.231
stock_price{type="watch",id="23561025",isin="DE0005089031",name="United Internet",currency="EUR"} 13.114
stock_count{id="23561025",isin="DE0005089031",name="United Internet"} 2

Example of Prometheus query to see the current value of all the stocks with a specific ISIN:

stock_count{isin="US88160R1014"} * on(id, name, isin) stock_price{type="current",isin="US88160R1014"}
