Mi Mike,
I am trading EURGBP.
Q1) I currently have the 1H bar chart displayed on the screen. I do it “for a year” at 1M bar for parameter optimization. My question is, is 1 year the correct period?
Q2) In Q1), I optimized to 1M bar while having a 1H chart screen. Should I display 1M bar on the screen to match together?
Q3) What is the fixed value of spread of EURGBP?
Q4) There is something called “Download historical data for additional symbols to accurately convert profit to account currency.” What are the advantages of choosing this? Won't selecting this slow things down?
