The purpose of enabling a stop and reverse (SAR) function is because you believe that if your initial trade direction is wrong, the market will go in the opposite direction, and you want to catch the opposite move.
When you are stopped out shortly after your entry, the probability that your initial direction is wrong is very high, and the SAR strategy might work.
What if the market hits your first target, then reverses? Your initial direction might be correct, and you are stopped out by floor traders “running stops”. If you reverse in this case, you might be whipsawed.
The new options available in the latest version allow you to automatically cancel any SAR set initially if the market hits your T1 or T2, saving you from a whipsaw if indeed it is a whipsaw. The new options are located under the Trade Settings menu and is set for each symbol separately.
