Build yourself a trading plan that will guide you in the market, and this is actually the most effective way to actively remove the loss transactions due to emotion. 
This cannot totally remove the losses but atleast will be lessen the opportunity Plans are required in each action we do,and most speci specially if this includes our hard earned money so we must be ready to increase the chance of profits by creating a plans
You will not go to war without any plans on how to win unless you wan to suicide. Same as in trading when you should always have plans on every action or decision youve made. With this you can increase the probability of making the right desicions because you even have a plan B for failing.
well, in this matter of course we need a plan to avoid big losses. besides, without a plan, we can get a big loss. some people don't know what they should do when prices become unstable. it certainly makes them a loss.
