Potential resistance after historic high

It is a challenge to know when to take profit  after indices broke  historic high, therefore I am using HLY's theory (Hu Li Yang) as a guidance.

HLY's theory is potential resistance at every 15% interval from the previous historic peak.

For example. Dow peak in Oct 2007 at 13,407
The potential resistance levels are 15,418, 17,429,  19,440, 21,451, 23,462 and so on

S&P  also peak in Oct 2007 at 1,576.  The potential resistance are  1,812, 2,049, 2,285,  2,522, 2,758, ...

Nasdaq 100 peak in Mar 2000 at 4,816.  The potential resistance are 5,538, 6,261, 6,983,  7,706, 8,428, ...

Russell 2000 peak in May 2011 at 868.  The potential resistance are  998, 1,128, 1,259,  1,389, 1,519, ...
