fxtracker

This is a package created as a group project for DSCI_524 Collaborative Software Development of UBC Master of Data Science (MDS) program 2022-2023. Based on the foreign exchange data in Yahoo Finance, this package allows user to perform currency conversion based on the latest available exchange rate, lookup a target exchange rate from historical data as well plotting exchange rate history and profit/loss percentage history by specifying a currency pair (and other input parameters).

The full documentation of this package can also be found on https://fxtracker.readthedocs.io/en/latest/

Function Description

• fx_conversion
  Convert the input amount of currency 1 to currency 2 based on the latest available exchange rate.
• fx_rate_lookup
  Lookup for the most recent date on which the input target rate of a currency pair is within the day's high/low.
• price_trend_viz
  Plot the historical exchange rate of the input currency pair for a specific period of time.
• pl_trend_viz
  Plot the historical profit/loss percentage of the input currency pair for a specific period of time.

There is a python package (forex-python) relevant to foreign exchange. That package is basically for retrieving exchange rates and bitcoin prices in plain text as well as performing conversion. It does not provide visualizations and lookup function like fxtracker does. fxtracker allows user to visualize the trends and understand if a target price of a currency pair of interest is within a reasonable range.

Installation

$ pip install fxtracker

Usage

If the package is installed successfully, users then need the following nine input parameters:

curr, target_px, start_date, end_date, chart_type, option, curr1, curr2, amt. The output of the functions will be in forms of a datetime string, a float and interactive plots from the "altair" package.

fxtracker can be used to convert a specific amount of money from one currency to another, find the most recent date on which the target price falling between day high and day low of that day, visualize the trend of the exchange rate of a currency pair and the trend of the profit and loss of a currency pair between the selected start date and end date.

The functions can be imported from the package as follows:

from fxtracker.fxtracker import fx_conversion
from fxtracker.fxtracker import fx_rate_lookup
from fxtracker.fxtracker import price_trend_viz
from fxtracker.fxtracker import pl_trend_viz

To convert a specific amount of money from current currency (curr1) to desired currency (curr2):

fx_conversion('EUR', 'USD', 150.75)

163.68

To look up the most recent date on which the target price falling between day high and day low of that day:

fx_rate_lookup('EURUSD', 1.072)

'2023-01-10'

To visualize the trend of the exchange rate of a currency pair between the selected start date and end date:

price_trend_viz('EURUSD', '2018-12-01', '2022-12-01', 'High').show()

To visualize the trend of the profit and loss of a currency pair between the selected start date and end date:

If a line chart is specified in the input:

pl_trend_viz("EURUSD", "2020-01-01", "2022-01-01", 'line').show()

If an area chart is specified in the input:

pl_trend_viz("EURUSD", "2020-01-01", "2022-01-01", 'area').show()
