referencing the RhodesRept posted by be, the ratio rept. note Rhodes used INDU/COMPQ I am using INDU/NDX as it yields more TA info in the short term. and NDX is a surrogate for QQQ's
it would begin to fill the Gap in the chart above. and in the chart below, it would be cause a Turn, a new line of "O" signally, the mini-rally of "X's" is over and a new line of downers, requiring at least 3 boxes of downs before any Up can be EXCLAIMED.
So, if QQQ's are to remain Bullish, this ratio must stay above 7.00.
