thank you for the kind words.
The spreads from your broker look just fine I think. It is all right to place any link, only we do not allow broker’s links (affiliate links).
Keep in mind that Portfolio Expert Advisors with EA Studio are allowed only with Meta Trader 4. If you are thinking about placing different EAs on different chart windows than you can go for MT5. Anyway the Portfolio trading with one Expert Advisors is only for MT4. This is not restriction in EA Studio, but in MT5. Simply, the broker do not provide hedging in MT5.
Your strategy equity line looks very good!
