Intro

This is a DeGiro analytics platform. DeGiro is a low-fee Dutch investment broker that, sadly, offers limited account analytics functionality. This project leverages DeGiro's private API and provides some investment performance analytics tools.

Requirments

pandas>=1.4.2 requests>=2.27.1

Installation

pip install degiro_analytics

Docker

If you prefer to run the project in Docker, I made an image available in Docker hub. It contains a Jupyter Notebook with getting-started examples.

docker pull dpokidin/degiro-analytics-notebook
docker run -p 8888:8888 dpokidin/degiro-analytics-notebook

Just copy the link with an automatically generated token and plug it to your browser to run Jupyter.

Hint: Make sure you don't have any existing notebooks running on port 8888.

Description

degiro_analytics/DegiroWrapper.py contains API to retrieve current portfolio information and product search. It does not include trading API. There are open-source projects implementing trading API.

degiro_analytics/utils.py contains various methods for portfolio analytics.

Examples

import pandas as pd
from degiro_analytics import DeGiroWrapper
from degiro_analytics.utils import irr, analytics
DGW = DeGiroWrapper(True, True, base_curr='EUR') # you will have to provide your credentials (and possibly multi-factor auth code)

Insights into your portfolio

pf = DGW.get_current_portfolio() # retrieves your current portfolio

Get price history of your portfolio constituents

P = DGW.get_prices(pf.index)
P = P.pivot(index='date', columns='name', values='price')
P = P.apply(lambda x: x/x.dropna().iloc[0]) # normalize by starting price
P.plot(title='Portfolio constituents perfomance', figsize=(15, 7))

Perfomance of your account

start_date = '01/01/2020' # use any date
T = DGW.get_transactions(start_date) # trasactions history
P = DGW.get_prices(T.productId.unique()) # get price history of all products from T
P = P[P.date>=T.date.min()]
P = pd.pivot_table(P, index='date', columns='productId', values='price', aggfunc='mean') # product per columns
P.fillna(method='ffill', inplace=True)

Q = pd.pivot_table(T, index='date', columns='productId', values='quantity', aggfunc='sum') # number of shares purchased, product per column
Q = Q.reindex(P.index.append(Q.index)).sort_index().fillna(0).cumsum() # portfolio quantities per day

idx = P.index.get_indexer(Q.index, method='nearest')
matched_P = P.iloc[idx].values

The following cell computes portfolio returns as $R_t = \frac{Q_{t-1}'P_t}{Q_{t-1}'P_{t-1}}$.

numerator = Q.shift().multiply(matched_P).sum(axis=1)
denominator = Q.multiply(matched_P).sum(axis=1).shift()
R = numerator/denominator

IDX = R.fillna(1).cumprod() # index (or normalized price) of the portfolio
IDX.plot(title='Account Portfolio Perfomance', figsize=(15, 7))

Some analytics

analytics(IDX)

{'Mean return': 0.00027660251717962994,
 'Std': 0.010483131903391498,
 'Risk Adjusted Return': 0.02638548477007559,
 'Number of drawdowns': 28,
 'Maximum Drawdown': 0.25730401117784857,
 'Max drawdown duration (days)': 320,
 'Mean drawdown duration (days)': 26.035714285714285,
 'T': 570}

Cash Flows analysis and money weighted return (IRR)

cf_df = DGW.get_account_cash_flows('01/01/2000', fees=True, dividends=True)
cf = cf_df.set_index('date').CF
cf.loc[pd.to_datetime(DGW.today, dayfirst=True, utc=True)] = pf.Q.multiply(pf.price_base_curr).sum() # current portfolio value

mwr = irr(cf)
print('Money weighted return is', mwr)

Money weighted return is 0.008600000000000003

Search products

search_text = 'Microsoft'
product = DGW.lookup(search_text, limit=1)[0]
print('The current price of', product.name, 'is', product.closePrice, product.currency)
p = product.get_price_hist(convert=False).set_index('date').price
p.plot(title=product.name, figsize=(15,7))

The current price of Microsoft Corp is 229.25 USD

search_text = 'Apple'
product = DGW.lookup(search_text, limit=1)[0]
print('The current price of', product.name, 'is', product.closePrice, product.currency)
p = product.get_price_hist(history='1D', resolution='T1M', convert=False).set_index('date').price
p.plot(title=product.name + ' (intraday pricing)', figsize=(15,7))

The current price of Apple Inc is 140.42 USD

Search and analyze ETFs from core selection

etfs = DGW.search_etfs(only_free=True, limit=200) # returns all ETFs from DeGiro core selection

Loop through the ETFs and analyze the prices

out = []
for etf in etfs:
    p = etf.get_price_hist(resolution='1M')
    a = analytics(p.set_index('date').price)
    a['name'] = etf.name
    out.append(a)

pd.DataFrame(out).sort_values('Risk Adjusted Return')
