I'm sure this subject has been discussed many times but I still would like to know how others are doing it today.
AIMS manual states that the lot size should be calculated based on AIMS levels. I'm using this approach at the moment. For a long time I have thought that it's causing a headache for me because when the AIMS box is very tight, you will get bigger lot size, even the slightest move will stop you out and eventually bigger loss. Of course you will get more easily 2:1, 3:1, x:1 trades. But for me I don't like this approach.
Based on journals I have a feeling that some of you are using fixed 10 pips when calculating initial SL. With this approach the losses really would be minimal. This approach is the one that really would fit to my brains.
Or am I understood everything wrong

What approaches you are using?
