#macro #weekly #cycle analysis #FLD #Hurst
JM Hurst proposed using the tool called Future Line of Demarcation to identify underlying cycles. In essense FLD is price of a stock shifted by n bars forward. That lets a trader quickly identify potential turning points.
My favorite periods are 8 and 21.
Let’s look at how SPY weekly has been interacting with its weekly 8 FLD this year:

SPY and its 8 weekly FLD have been perfectly inversely correlated.
Note how well weekly FLD 8 has been pointing to turning points in SPY.
Note the acceleration starts when price cross over or under the black FLD line (the classis way of using FLD).
