For those interested, here are the calculations for both Negative and Positive price directions.
V Calculation: V = B + (B-C) for Positive and V = B - (C-B) for Negative.
N Calculation: N = C + (B-A) for Positive and N = C - (A-B) for Negative.
E Calculation: E = B + (B-A) for Positive and E = B - (A-B) for Negative.
NT Calculation: NT = C + (C-A) for Positive and NT = C - (A-C) for Negative.
