Can you elaborate a bit on the time series thing and fast Fourier?
Thanks!
The pitchfork i guess measure the median of the cycles!?
Median Lines (or your referenced: Pitchforks) DO NOT measure cycles.
Median Lines show the probable path of price and price targets. It is a leading indicator. It can be used to assimilate market structure, trade location, entry points, risk management, and price targets.
See attached example slide. The median line and analysis was performed, Before the trade, and the price action shows the results. Notice how price action hits the upper median line and then retraces. It was at this time, that TSLA released news.
Average True range is only used to evaluate volatility.
This goes back to the likes of Roger Babson, founder of the NQB.
