A trader needs to create rules and follow them when the psychological crunch comes. Set out guidelines based on your risk-reward tolerance for when to enter a trade and when to exit it. Set a profit target and put a stop loss in place to take emotion out of the process.
In addition, you might decide which specific events, such as a positive or negative earnings release, should trigger a decision to buy or sell a stock.
It’s wise to set limits on the maximum amount you are willing to win or lose in a day. If you hit the profit target, take the money and run. If your losses hit a predetermined number, fold up your tent and go home.
Either way, you’ll live to trade another day.
