It works well with the Zipline open source backtesting library. Print(df.tail()) # I use tail, beacause of the size of your window. pyfolio is a Python library for performance and risk analysis of financial portfolios developed by Quantopian Inc. Print('In case you want to check the result data\n')

So the code is the following import pandas as pdĭf = df.returns.rolling(180).apply(lambda x: (x.mean() - 0.02) / x.std(), raw = True)ĭf > 0].rolling_SR.plot(style='-', lw=3, color='orange', The dash line is just a Benchmark for the rolling Sharpe Ratio, the value is 1.6.Here I have defined "on the fly" the calculation of the Sharpe Ratio, please consider for your solution the following parameters: I have prepared an alternative solution to your question, this one is based on using solely the window functions from pandas. Is it possible to plot a 6-month rolling Sharpe ratio that changes from one day to the next? In the example plots, they appear to be showing many ratios. This value is the same for all the Dates. The problem is that I am getting a horizontal line since my function is giving a single value for the Sharpe ratio. Plt.title('Rolling Sharpe ratio (6-month)') Return np.sqrt(126) * (y.mean() / y.std()) # 21 days per month X 6 months = 126ĭf = calc_sharpe_ratio(df)ĭf.plot(style='-', lw=3, color='indianred', label='Sharpe')\ Here is the equation I am using: def my_rolling_sharpe(y): The type of plot I am trying to produce is this or the first plot from here (see below). My input data is below: import pandas as pdĭf = np.random.rand(d.size, 1) The examples in this guide will assume that the import statements below are included at the top of the Python script or Jupyter Notebook.I am trying to generate a plot of the 6-month rolling Sharpe ratio using Python with Pandas/NumPy. So the field can be left blank if your holdings do not include this information. The OpenBB SDK can figure out by itself what industry, sector, country and region belongs to the loaded in Equity. The template Excel file also has additional columns but these are optional.
The table below illustrates the required column titles: Date Portfolio or Sell/Withdrawal/0 to remove from the portfolio a search criteria,
Your Excel file should then be one of the options.

How to Use īelow is a brief description of each function within the Portfolio module: PathĪllocation Metrics Compared to the Benchmark Here we are going to create a portfolio whose weights are identical for each of the instruments, not differentiate the type of strategy. This guide will introduce the functions within the main Portfolio module, and walk through examples demonstrating how to work with a portfolio file and object. The Portfolio menu, from the OpenBB Terminal, is wrapped into a Python SDK layer, enabling users to programmatically work with the data in a flexible environment, fully customizable for the needs of any user.
