Because some markets are very "expensive" and do not offer a mini or micro contract, many traders have to stick to a single contract once in a while.
In this case, you might trade a single-lot strategy. Finding the right target for a single-lot strategy is tricky and depend on your general trading strategy. You have to study your results to see what target gives you the best performance. You need a Trading Journal with all your trades and you need to go through your numbers to see what target will work best for you. For my own trading, the second target (T2) plays the most important role. It is about twice the initial risk and it gives me the best performance on the long run. That's why I am focusing on T2 even when I trade multiple lots.
You might also want to use a simple trailing stop without any targets at all. But with this strategy you need a couple of nice runners during the trading year because very often you have to give back some parts of your paper profit.
But as I already mentioned above, you need to check your own trading results to find out which one-lot strategy gives you the most profits.
