I'd be taking profits mid-morning before the rush out the door going into a 3 day weekend. Its also Easter weekend which could be an open season for terror attacks. Since the odds increase for some terror drama this coming weekend many will want to go home lite.
I think the situation was set up that good for this pop. I postulated we were in the ii of 5 when we dumped at the end of the day, the iii of 5 up would then take us to around NDX 1508, with the iv of 5 back down to maybe 1495 and the v of 5 up to maybe 1512 or 1518 NDX.
