I am trying to find out how to calculate performance between two dates (a given start date and end date) for an equity, bond and a fund. Is this something that is available under reuters ? In Bloomberg this functionality is available under COMP and it is possible to calculate the performance between two given dates.
Finally I would like to use that under AppStudio, to be able to fetch this calculation from a given start date, until up to date or until a given end date. I tried to look for some codes, I only found performance since sinception to date or to month end for funds, but this is not what I am looking for.
I apologize if this is not the right place to ask this kind of question, please direct me towards the right person.
Thank you for your help,
