Be willing to stop trading and re-evaluate the markets and your methodology when you encounter a string of losses. The markets will always be there. Gann said it best in his book, How to Make Profits in Commodities, published over 50 years ago: “When you make one to three trades that show losses, whether they be large or small, something is wrong with you and not the market. Your trend may have changed. My rule is to get out and wait. Study the reason for your losses. Remember, you will never lose any money by being out of the market.”
