currency-tracker

Description : A currency exchange tracker based on Boursorama Website.

The idea is to gather information is order to feed a dataset in a first step.
Detect and study the algorithme that lead to influence each currency
Produce a model.

HOW It WORKS

The exchange dict store the revelent value and condition to trigger a notification, ex when a currency is higher or lower than a certain value (bestrate)

exchange = [
    {'devise': 'EUR-MAD', 'condition': '>=', 'bestrate': '10.97', 'weight': 0},
    {'devise': 'EUR-USD', 'condition': '>=', 'bestrate': '1.1944', 'weight': 0},
     {'devise':'USD-MAD','condition':'<=','bestrate':'9.3529','weight':0},
      {'devise':'JPY-EUR','condition':'<', 'bestrate':'0.75166','weight':0},
      {'devise':'CNY-EUR','condition':'>', 'bestrate':'0.12832','weight':0}
]

Rotation : Random but the last one :

This algorithme avoid to check the same currency twice, so the idea is to rotate over other currency randomly.

        while index == last:
            index = random.randint(0, len(exchange) - 1)

The configuration is inside the python script :

Sleep between checks :

In order to do a clean check and not subcharge the server side, we do a sleep between every check the value is the modulo the variation, as the variation could be negative then the higher the shorter the sleep is , long when the variation is negative.

        while index == last:
            index = random.randint(0, len(exchange) - 1)

The configuration is inside the python script : Requierements

This code could be run on a linux machine :

this is systemD configuration to set it up as a deamon :
