I want to write an indicator defining the Value Area (VA) (zone that is about 68.2%), but I cannot find the calculation algorithm.
I guess that exist several standart algorithms.
Could you help me to find them?
I'll be grateful for links or algorithm description here.
What's the input data?
What should be used TPO - Time Price Opportunity or POC - Point of Control?
How is calculates Value Area Low (VAL) and Value Area High (VAH) correctly?
