risktools 0.2.8.1

Python implementation of the R package RTL

risktools

Python implementation of the R package RTL.

See CRAN for original R version

https://cran.r-project.org/web/packages/RTL/index.html

Purpose

Purposely designed functions for trading, trading analytics and risk practitioners in Commodities and Finance.
Build to support delivery of Finance classes from one of the co-authors of RTL at the Alberta School of Business.

Version Notes

Note that the latest version will require compilation on Windows for python version 3.11 due to the 
dependency on arch. Arch does not come with binaries and must be compiled on Windows which can be
avoided by installing numba, however numba is not yet available for python 3.11.

Features

Historical forward curves charting.

Calendars and expiry dates data objects for a wide range of commodity futures contracts.

roll_adjust to adjust continuous contracts returns for roll adjustments using expiries above.

chart_zscore() supports seasonality adjusted analysis of residuals, particularly useful when dealing with commodity stocks and/or days demand time series with trends as well as non-constant variance across seasonal periods.

chart_eia_steo() and chart_eia_sd() return either a chart or dataframe of supply demand balances from the EIA.

chart_spreads() to generate specific contract spreads across years e.g. ULSD March/April. Requires Morningstar credentials.

swapInfo() returns all information required to price first line futures contract averaging swap or CMA physical trade, including a current month instrument with prior settlements.
