Timber-Online's editorial team does research on global prices of sawn timber, manufactured products and wood residues. These are then used to calculate the sales indicator, according to a system developed by the University of Natural Resources and Life Sciences. The sales indicator's goal is to reflect the market situation of the European sawmill and manufacturing industry. 100% correspond to a normal sales situation. Values over 100% reflect a positive, values below 100% a negative market situation. The sales indicator is published on a monthly basis.
