Someone says its harder to get a perfect entry than a nice exit. You can enter the market anytime you want and make profit but if you don't have any plan to exit from the market then your profit will only satisfy your eye not your pocket. So we should know when it is time to exit from the project we get in the bear market when everything was dumping. That is the reason a money management strategy is an important part of a trader's life. Everything needs to be according to the plan.
