int Stock::LoadDictionary

(

std::string

dict = ""

)

Load the dictionary of Stock, see ServerPortfolio.

int Stock::UpdateStocks() { std::cout << "Entry Parser UpdateStocks in StockwrapParser.cpp" << std::endl; Py_Initialize(); PyRun_SimpleString("from ParserStocks import ParserStocks\n" "import DictStocks_Parser\n" "parserstocks = ParserStocks( 'CAC40', 'Yahoo_CSV' )\n" "parserstocks.myparser._SetCodeYahoo('^FCHI')\n" "dict_stocks=DictStocks_Parser.Init()\n" "retour = parserstocks.UpdateCSV()\n"); Py_Finalize(); std::cout << "Exit Parser UpdateStocks" << std::endl; return 0; }

Load module DictionaryStocks and call its constructor
To call after PyInitialze() ( to check, seems logic ) name of the txt file, now use default only

Parameters

dict	name of the dictionary

Returns

status, 0 for ok, -1 for error

int Stock::UpdateCSVFromWeb	(	const std::string &	source,
		Utils::firstlast_dates	opt_dates = Utils::get_fldate_default()
	)
throw	(	StockException
	)

Normal use case : Get missing daily data, call Yahoo and then save to file.

Precondition

If the List is already loaded in Stock, the last data must be => Header.last (else return -1)

Postcondition

Should not loose any data in loading new data and saving to file.

Parameters

source	which website to use "Yahoo" (or "Boursorama" other function can combine later?)
opt_dates	optional, limit the range of the data to retrieve, default [last data(header or memory)+1, today]

Returns

number of new data added to the list, 0 means nothing new , -1 CANNOT_UPDATE

Exceptions

StockPythonException

in case of problem in loading modules
