In an earlier chapter, I mentioned that many trade setups will be violated.
In other words, the market often will not hold above the price level or zone
of one of the buy setups defined in Chapters 6 through 8, or not hold below
the price level or zone of one of the sell setups defined in those same chapters.
We know that these trade setups are important market decisions;
however, we don’t know in advance whether or not a particular zone will
hold. To increase the odds for success in trading using these trade setups,
we ideally want to use trade filters and/or a trade trigger.
