I put a report together tracking the price ratio from past highs to project a possible date for the next all time high.
Basically it looks at the current level (how much has it dropped from the past high) and its trend (up or down) to find dates in the past with the same conditions. Then these dates are scanned forward to the next ATH date and the number of days are averaged together to give a guess for the next. This is to say if the trends continue in similar proportions.
Questions are welcome.
