QUESTION

Why does the Quantlib::Error class allocate a std::string on the heap?

Asked 2022-Mar-11 at 02:18

In a code review recently, I had some less than kind words for something I thought awful. It turns out that it was obviously inspired by the QuantLib::Error class, which looks like this:

...

ANSWER

Answered 2022-Mar-11 at 02:18

This is following the behavior of standard library exception types.

They are supposed to be copyable without throwing exceptions, since throwing an exception during construction of an exception handler parameter would cause a call to std::terminate (and possibly in some other situations requiring a copy of the exception as well).

If std::string was used directly, copying the exception could cause for example a std::bad_alloc to be thrown. Using a reference-counted pointer instead avoids that.

The canonical way to structure a Class (and to avoid the "name 'self' is not defined") error

ANSWER

Answered 2022-Jan-26 at 23:39

I recommend a reading of the Python documentation about classes.

Q1. What is causing the NameError: name 'self' is not defined error in the class above?

A: self refers to an object of a class. You cannot reference an object before you create one.

Q2. Would someone kindly show me the correct (i.e. canonical) way to write this class?

A: You could add the class properties you defined to the __init__ method, as you did with some properties.

Compare QuantLib bond pricing with Excel functions YIELD and PRICE when doing stress testing

Asked 2021-Nov-23 at 08:29

I calculated bond price and stressed bond price (shocking up yield) in both Excel and Python Quantlib. As the following table shows, weird results were generated: base bond price matches well between Excel and Quantlib but the stressed bond prices have more gaps (1.5% relative difference). Yields also show some gaps. Can you please provide some comments?

brace-enclosed initializer list conversion error

Asked 2021-Sep-29 at 18:58

I have the following old code that used to work on "older" combinations/versions of C++, QuantLib and Boost. While was playing around with the idea of upgrading to newer versions ie C++11, QuantLib >= 1.76, boost >= 1_71 building now throws the following "conversion" error(s).
I am using [options] g++ -std=gnu++11

ANSWER

Answered 2021-Sep-29 at 18:58

The errors are narrowing conversions, which are never allowed in uniform initializers.

That's relevant because aggregate initialization existed all along and did not have that restriction. Now in C++11 world, aggregate initialization is just a form of uniform initialization, with ditto narrowing rules.

You should explicitly convert the respective values (checking that the conversion is safe!)

Pricing a Forward Rate Agreement using QuantLib Python

Asked 2021-Sep-07 at 14:13

Can someone please help with the pricing of the following forward rate agreement using QuantLib Python?

A 3x6 forward rate agreement, with a notional of $100,000, the FRA rate being 6%, The FRA settlement date is after 3 months (90 days) and the settlement is based on a 90-day USDLIBOR.

My valuation date is 30 June 2020.

This is my attempt:

...

ANSWER

Answered 2021-Sep-07 at 14:13

First off (for accuracy) the daycount for USD FRAs is Act/360, ie ql.Actual360(). Also bear in mind that the fixing calendar for FRAs is based on the UK calendar (BBA Libor), which may be different from the settlement calendar (so 4th July is not a fixing holiday, but is a settlement holiday).

The main issue with the OP code is that the FRA start date is the same as the evaluation date. Once you know the fixing, then the FRA is effectively settled, so has a NPV of zero and a cashflow.

The first parameter of ForwardRateAgreement() is the settle date of the FRA. The second, maturity, is the end date. So for a spot 3x6, the start date is 3m from now, and the maturity is 6m from now.

Amending this line to:

dayConvention = ql.Actual360()

and

fra = ql.ForwardRateAgreement(calendar.advance(startDate,ql.Period(3,ql.Months)), calendar.advance(startDate,ql.Period(6,ql.Months)), ql.Position.Long, rate, notional, index, spotCurveHandle)

will give you the dates for a spot 3x6 FRA (30-Sep-20 -> 30-Dec-20).

Output: NPV: -262.08622386063985

NB. In the QuantLib example for FRA's, they use a selection of FRA market rates to build a PiecewiseLogLinearDiscount curve to value the FRA, rather than a zero curve, and I guess it is the subtle differences between the two which is leading to the slight change in forward rate (and hence NPV). The implied forward rate for the FRA comes out at 4.937% ... ie not 5%, which also increases the NPV. In practice, if you are trying to price FRAs then build a curve using market FRA quotes.

Undefined Boost symbol when linking to pre-compiled QuantLib binaries on MacOS

I am trying to compile some C++ that depends on QuantLib, which in turn depends on Boost. I am working on a MacBook Pro M1 (ARM architecture).

I think you're missing a -lQuantLib in your command line? You're telling the compiler where to look for the libraries (the -L switches`) but not which libraries to link.

Also, check whether homebrew also installed a quantlib-config script on your computer. If so, it should provide the switches you need; try running

if(i < 1){

      } else {
        fund_table_xts_fin <- merge(fund_table_xts, fund_table_xts_fin)
      }


In the above section when i = 1 then you are in the else block but there is no 'fund_table_xts_fin' object created yet. You can try this:

`if(i == 1){
    fund_table_xts_fin <- fund_table_xts
  } else {
    fund_table_xts_fin <- merge(fund_table_xts, fund_table_xts_fin)
