The cancelling.
Your first response, I just finished reading now. It is very hard for me to get it, I need to sit down and go through it bit by bit. The thing is, I am maybe really weak in this discipline. I remember this feeling from math school, where i had to go to a small class with only 5 people and there i was the one who never got it.After I ran away from school I felt so good and free. But back to topic, I will tell my advicer that I am pretty dumb with these things and ask him if he can just tell me where to enter the numbers and then see what happens.
Thanks a lot, I will try to understand but it looks like your explanations is like jewels for the pigs it seems. Who knows, I have the feeling, that with little little steps I could make it and become a trader one day.
