The paper concerns real time estimation of the underlying trend of a time series by means of filters that arise from fitting a local polynomial of a given degree with a constant bandwidth. The direct asymmetric filters that arise by fitting a local polynomial at the boundaries are analysed and a new class of real time filters is developed.
