No matter what kind of deviation, it is a phenomenon of uncoordinated times. For example, the price has hit a new high, but the index has not hit a new high.

Generally speaking, the deviation may indicate that the price will turn around or there will be a correction. Using this, we can form an opening signal and build a trading strategy.

However, like all other trading strategies, any signal used to open positions should take into account the countermeasures when the market is inconsistent with expectations.
