So TIA as a proper technique for forecasting the oil price is described and applied here. The results of this forecasting which was included oil price in period of 2007 up to 2008, has been registered before in 2006 as a scientific paper, and now after about 18 months, we are comparing the results of the forecasting and actual data. Validation of the technique is the aim, which we got to it in this paper.
