Is wave 4 done at a little more than 23.6% retracement? Wave four is a flat and wave 2 was zig-zag retracing 61.8%, so we have alternation. Nvidia is now at the 20-week average so that is an ideal support as well which held in wave 2 too. Wave 5 should follow wave 4. 5=1 then the level is at 300 which should coincide with the top end of the channel. A rising channel has been drawn keeping the most recent low as the pivot. The 20wma is at 418.
