TRIN when all stocks up/ down

Generic

Hi,



When we caculate the TRIN for some index, with less constituents, say Hang Seng Index, how to handle the situation when all stocks up or down?



Thanks.

One solution could be, you can calculate the TRIN on higher frequency data such as 30 minute or 1 hour.  Then take the moving average to smooth it out. The cases where declining stock are zero you can default it to 1 and when advancing stock are zero you can default to the highest value the range or to the previous value.



I hope this helps.
