# 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.

## 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.

    Morningstar Marketplace API functions getPrice(), getPrices() and getCurve() using your own Morningstar credentials. Current feeds included:

    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.

## Data Sets

    expiry_table: Historical and forward futures contract metadata.
    holidaysOil: Holiday calendars for ICE and NYMEX.
    tickers_eia: Mapping of EIA tickers to crude and refined products markets for building supply demand balances.
    usSwapIRDef: Data frame of definitions for instruments to build a curve for use with RQuantlib. Use getIRswapCurve() to extract the latest data from FRED and Morningstar.
    usSwapIR: Sample data set output of getIRswapCurve.
    usSwapCurves: Sample data set output of RQuantlib::DiscountCurve().
    cancrudeassays contains historical Canadian crude assays by batch from Crudemonitor. cancrudeassayssum is a summarised average assays version.
    crudeassaysXOM for all publicly available complete assays in Excel format from ExxonMobil
