The problem is to calculate the cash flow schedule for a simple fixed rate loan where principal amortization periodicity is not equal to interest payment periodicity. For example, amortization is every 6 months and interest is paid every month. The key difficulty in implementing this via TradeType = Bond is that the ORE will pay interest on each amortization date

Has anyone solved a similar task?

  • $\begingroup$ I'm a little confused by your question: are there some dates where some principal is paid, but not interest - this happens in practice, and is hard to do in many libraries - or just some dates where interest is paid and zero principal is paid? $\endgroup$

  • $\begingroup$ OK, it wasn't clear. Yes, it's pretty common with loans, but many libraries, including Quantlib, which ORE uses heavily,don't bother implementing this feature because it's tricky: the interest accrued over a period duing which the outstanding principal varies. I mentioned it here quant.stackexchange.com/questions/58919/… $\endgroup$
