Hello Leonard,
Welcome to the Forum. I would suggest you first complete the course, and I am sure you will find the answers to most of your questions.
However, here are the answers.
1. You can use the Robot and the NLF with any loss you wish. obviously, if you use smaller lots, the profit will be smaller. For example, if you trade with 0.1, the profit will be $21 instead of $210(trading a complete 1 lot).
2. You can trade in both directions, it is up to you. In the course, I show how I combine it with the trend, so the entries are stronger.
3. This robot is designed to work with the NLF. That is why it has a TP of $210. Also, there is not SL, because we use the NLF. This is why you might see the loss because there is no SL and you didn’t use the formula to exit.
Cheers,
