You need to know what you are trading, what direction you want to be trading in, where you would buy and sell and where you would get out at a loss or a profit. You need to know all of this before the market opens and before you take your trade.

If you start to analyse where to get out at a loss or a profit when you are already in the trade then you can only make an emotional decision based on how much money you are up by or down by.

Write down your trading plan, like a business plan and every day, or week, you should be reflecting on how well you executed your plan. Not how much money you made or lost
