infer_conforming_time_grid {ragtop}

A time grid with extra times inserted for coupons, calls and puts

Description

At its base, this function chooses a time grid with 1+min_num_time_steps elements from 0 to Tmax. Any coupon, call, or put times occurring in one of the supplied instruments are also inserted.

Usage

infer_conforming_time_grid(min_num_time_steps, Tmax, instruments = NULL)

Arguments

min_num_time_steps

The minimum number of timesteps the output vector should have

Tmax

The maximum time on the grid

instruments

A set of instruments whose maturity and terms and conditions can introduce extra timesteps. Each will be queried for the output of a critical_times function.

Value

A vector of times at which the grid should have nodes
