Market price often comes back to popular chart levels like Round Numbers / Pivot Points and frequently penetrates them to trigger mainstream trading signals and to run for stops. Particularly, market Highs and Lows are important Manipulation points, where false price breakouts (false first breakout) occur to clear stop loss orders and to trigger breakout limit orders before market reverses back. Be careful with these mainstream trading strategies. Moreover watch out for pure stop runs at these chart levels, which can lead to a strong market turn around. In general, the first price breakout at important chart levels is often a false one.
Moreover, a clean break through a striking trading level without an immediate price retest is seldom and if so then the chance of a retest in near future is likely to catch stop orders of the breakout traders and to minimize the chance of an easy trade with a small stop lose at important price levels. Furthermore, the reiterating stop triggering process at striking chart levels would be in favour of a clean breakout to happen more often in the absence of any market price manipulation.
