Choosing the right money management for the expert advisor

If we know the answers, then we will know how much we can trust the expert advisor.

For example, let's say we have an expert advisor that trades a forex pair with big interest differential.

We analyze the expert advisor and find that it trades only on the positive side of the swap, and it is winning because of it.

This means that there is a high chance for our trading robot to work until that swap number is in a specific range.
