Could you also tell us what your zorro version is?
I think I started with 1.74 and upgraded to 1.83 a while ago.
Skipped trades just means there was a trade signal but it was skipped because of insufficient margin. It's not abnormal, but it may mean your capital slider is set to high in relation to account equity.
Re: assetfix, just add symbol overrides if needed (and that is broker specific). There's no need to mess with anything else for live trading. The rest of that stuff is for backtesting.
If you want accurate backtests for your broker, use the download script to create a csv specifically for your broker with the right spreads, lot amounts, margincost, and so on. The manual has instructions for this.
