>>I wonder what is better: support/resistance breakout or reversion to
mean. <<
There is no better, just different.
Let me 1st define what S/R means to me, it is a place where prices
have previously stopped and reversed direction. S/R points frequently
get retested. They are not exact numbers, over shooting and under
shooting a little bit on a retest is common.
If S/R is penetrated, it reverses its significance, i.e., S becomes R
and vice vesra. If S/R gets pentrated in both directions, it looses it
significance as S/R.
Breakouts of S/R work best for trading range breakouts and in strong
trends, in the direction of the trend, especially early in the trend.
The later in the trend, the greater the risk the breakout won't work.
Reversals at S/R work best in a choppy sideways market and when
trading pull backs in the direction of the prevailing trend.
There are also many techniques (Fibonacci projections, Gann
projections, floor trader pivots, O/B O/S indicators like LaguerreRSI,
statistical measures, etc) to help decide when a market is ripe to
regress to the mean.
