1	getDailyOHLC(searchDates, isin, input_df)

`searchDates`	- vector of charachters with different (formats see examples) Date requests: e.g. 20.09.2014-22.09.2014 (normal time period between two dates) // 08.2014 (short for one month) // 2014 (short for one year) // 20.08.2014 (short for one day) // 2013-2014 (time period between two years) // 08.2014-09.2014 (time period between two months)
`isin`	- vector of characters with the id number of the stocks (ISIN = International Stock Identification Number)
`input_df`	- data.frame with dates(as character in format dd.mm.yyyy, e.g. 21.02.2008 (

data.frame : date, isin, open, high, low, close, currency, volume, turnover This method crawls through the ariva.de website and grabs the daily price data out of the html tables. You can get OHLC data from specific dates for specific stocks (ISIN required). Either on putting the different stocks/isins and different dates for prices in a data.frame (input_df). This is good to get different prices on different dates and different stocks. or by delclaring a vector of dates/intervals and stocks/isins. This is good for comparing the prices on different time periods within a stock or with other stocks. The date must be in the right format (dd.mm.yyyy) as a character. It is not checked if the date is a correct trading day. It is also not checked if the date intervals are correct.

Status Quo: - Only Xetra price data - price data is cleaned up from stock splits (clean_splits)

The method strictly depends on the website structure of ariva and GET request of the csv file!
