Detailed Description

Source file for the library wrapPyStock.so imported by the python modules to access Stock functions.

wrapper to functions:

• LastCSVUpdate() get the last update from the header file (used only with DAY)
• UpdateCSV() update DAY historical data, with the Yahoo parser
• SaveInst() save Instantaneous data to file, respect format and update the header

Not a API to Stock.
Ideally Python should have equivalent python functions to be able to be used without this module.

static PyObject* wrap_LastCSVUpdate ( PyObject *  , PyObject *  args  )

Get last date available from file (only DAY at this stage).

Called by python: wrapPyStock.LastCSVUpdate()
Call from python:

date_time = wrapPyStock.LastCSVUpdate( self.symbol, GlobalDicts.TEST_MODE ) 

symbol name, symbol of the stock
boolean true will read file from data_test directory, false from data

Here is the call graph for this function:

static PyObject* wrap_SaveInst ( PyObject *  , PyObject *  args  )

static

Save instantaneous data into file.

The data are written in the format defined by C++, the header is also correctly updated.
Updated file : historical/SYMBOL.INST.csv

Call wrapSaveInst( symbol, [date,value], bool_test )

Parameters

args	: symbol, data consists of [date,value], boolean tmp will uodate the file in data_test directory

Returns

Python wrapper to Stock::wrapUpdateCSV().

wrap_UpdateCVS(symbol,list_data)
Call need symbol and a list of DataCVS
include volume in data, will be split in the function list_data format = [ [date,op,pl,mo,cl,vol],[date,op,..] ]

Here is the call graph for this function:

long int wrapLastCSVUpdate	(	const char *	symbol,
		bool	btest
	)

Get last date available from file.

Here pure C++, called by wrap_LastCSVUpdate which translate python argument and return
Create a stock, call stock::LastCSVUpdate and delete it at the end

Now call static function, read only ETime::DAY, need to extend ?

Parameters

symbol	name of the stock
btest	boolean variable to read data in data_test/historical and write in data_test/historical_tmp

int wrapUpdateCSV	(	const char *	symbol,
		std::vector< DataCSV > &	new_csv,
		std::vector< SimpleData > &	new_vol,
		bool	btest
	)

Uses to add data from yahoo (DAY) for StockCSV and Volume.

From Yahoo we get historical data in DAY, want to save permanently.
Boursorama Inst data, python adds by itself / send to the server, could also call a function of Stock test version, write complete data in tmp subdirectory.

Todo:

writing data with option, directly in /csv

check the order of the data and consistent with ListDataStock

Parameters

symbol	of the stock, given by dictstocks.txt
new_csv,new_vol	vector with new data
test	if test in true, read data from data_test, writes output data_test/historical_tmp
