A potential impulse may be developing in SPX from the low (Chart 1), potentially to launch wave five up (Chart 2) highlighted in recent weeks. Note that wave four down, if complete, retraced a fib-0.382 of wave three up.
Can it be a bull trap, at least for the short term? Yes and time will tell. By measurement, a potential expanding (solid red line) or contracting (dashed red line) diagonal triangle is a possibility (Chart 3).
