In order to test the accuracy of our forecasting, we designed a special method which allows us to calculate level of prediction ACCURACY (go to Forecasting Basics to learn more about forecasting accuracy).

The main reason for calculating ACCURACY is to scientifically analyze the quality of prediction. FORECASTING ACCURACY is an actual accumulated record of statistical difference of the forecasting price on a trade and the actual fill price.

For instance: "open" quotes hypothetic company XYZ was predicted at $20.50, but actual opening was $20.00 in the same trading day. The ACCURACY of the "open" price prediction calculates as 1.00–abs(20-20.50)/20, and will be equal 97.5%. ACCURACY is calculated for open, close, low, high and average quotes, for every day of trade, going back 50 days from the last day of trade, to the same trading day of the actual historical quotes. The next step is to add all 50 historical days "open" prices ACCURACY together, statistically forming a single number AVG ACCURACY. Finally, the program will calculate AVG ACCURACY for "close, high, low and average" the same manner with the investor being able to view the results printed on the last row of the forecasting table.
