trade timing signals - using Advance-Decline line tools

great quality review for August 13 RAVI

the NDX 100 A-D line 50,2 BB width continues to decline for several weeks, so a period of lower volatility for the NDX 100 A-D line BB's is in play … when will
this condition change? the BB width is now at the lowest level seen in the May to August 2018 period

the NDX 100 McSum is below its 5-day sma and is recently declining again
AND this McSum is not yet below the early July 2018 low, so the bulls still have a small amount of McSum room for a "save" and a McSum return to the upside … this save will be critical to the future probability evaluation for a future McSum and NDX price advance
