Why doesn't my stop loss order get executed after I reach the price I want?

This situation can occur when there is not enough market depth available for that security. For example, you set a stop-loss at ₹90 for a stock & there are 50 buyers and 100 sellers who are waiting to trade on this script at ₹90. Upon reaching ₹90, the first 50 sellers’ orders will be executed, and the remaining sellers will have to wait for new buyers. As a result, your order will not be executed if there are no corresponding buyers.
