Average value. Average true range for a given number of periods can be calculated after calculating the true range values for all those periods. The popular number of periods for ATR is 7 (proposed by the indicator's author in his book New Concepts in Technical Trading Systems) and 14 (used, for example, in MetaTrader default settings).
The rate of return calculated by IRR is the interest rate corresponding to a 0 (zero) net present value. The following formula demonstrates how NPV and IRR are related: NPV(IRR(A2:A7),A2:A7) equals 1.79E-09 [Within the accuracy of the IRR calculation, the value is effectively 0 (zero).]. number that you guess is close to the result of IRR. Microsoft Excel uses an iterative technique for calculating IRR. Starting with guess, IRR cycles through the calculation until the result is accurate within 0.00001 percent.
