In my Algo, Probability Boxes once started remains (dashed lines) until they be broken in the opposite direction with the counter trend continuation.
This would be the case with S&P500 INDEX reached up again the 3,654/3478 -83% Short Top Probability Zone, targeting 3,345.80 (3,357/3,238.00).
As it is normal, count is not clear so far. That´s why I rely on probabilities.
