Pre-Monday's stock markets openings - here is the Nasdaq100 index on a week to week basis, and day to day basis. Both presented in Heikin Ashi terms. 

NASDAQ100 WEEKLY

There is no doubt the weekly chart is showing extreme strength. Until markets violate the 14.476 level, marked in the diagram, the medium term upside could still be intact. 

On a daily basis. The pattern is quite different. Let's have a look below.

NASDAQ100 DAILY

This Nasdaq100 chart is sited intraday by intraday. Friday closed a Red bar, which signals upcoming weakness (read the oposite in the pic for Blue). Now, the 'only' reference point seems to be 14.991 whcich is marked in Red. If the level is violated, there is a greater chance the upside will again resume. Until proven, indications are pointing lower for the index.
