Guideline 27. You need to be trading a size where you are comfortable with any decent signal and remain comfortable if you lose two or three times in a row

Guideline 26 Guideline 28

If you find that you did not take a couple of Emini trades in a row and they worked, you are likely trading too large a position size. Switch to trading 100 to 300 shares of SPY and swing for at least 20 to 50 cents. Even though you won’t get rich, at least you will make some money and build your confidence. If you think that you can comfortably trade three Emini contracts per trade, then you should trade just one. This will make it much easier for you to take every signal. If you trade three Eminis, you will let many good signals go because you really are comfortable trading only three contracts in the rare case of a perfect signal. You need to be trading a size where you are comfortable with any decent signal and remain comfortable if you lose two or three times in a row. One indicator of this comfort is your ability to take the next trade after those losses. If you feel too uncomfortable and are really waiting for perfection, you are still trading too much volume. Once you start cherry-picking, you are on the path to a blown account. Your emotions are a burden and give an edge to your opponents, as is the case in any competition.
