"(My IWM/RUT chart does not show the CCI 48 crossing above the -100 at the close on Friday, though. . . )"
FWIW Fidelity's Active Trader Pro has IWM CCI48, 15 min at -114.08 on the close. At 3:30 there was a possible HFE at -217.77. Depending on the open Monday I'll probably take it based on the trend line break and leteral support from the 23rd, 24th and 26th.
