Beginners should learn three facts first: a standard XAUUSD lot is 100 ounces, gold often moves $20 to $40 in a day, and lot size must be calculated from the stop distance.
A workable first 90 days: two weeks learning the gold specification and sizing on demo, two weeks marking the Asian range and London open without trading, six weeks trading one setup in one session while journalling every XAUUSD trade, then a review of expectancy by session before any live capital.
