The question is simple – there is an adviser, tested for each necessary asset separately. It seems that everything is good and beautiful, but: when testing for one asset, the margin calculation is not particularly taken into account. The yield curve depends again only on one asset. How can I run an expert Advisor on 3-5 assets at the same time? So that there is a complete analogy with the real – there is a drawdown, there is a profit, a yield curve, etc….
