Paper trading and demo accounts measure different things on gold: paper trading marks hypothetical entries on a chart with no bid/ask spread, no slippage and no order execution, while a demo account routes real orders against a live XAUUSD spread and real-time price movement.
Because gold spreads run $0.15 to $0.35 in London and New York hours and $0.50 or more at rollover, and because slippage on stops during the 13:30 UTC CPI/NFP window can reach $0.50 to $3.00 per ounce, paper-traded results systematically overstate expectancy on tight-stop gold strategies.
The practical sequence is to paper trade a new gold idea first for fast, low-cost screening, then finalise the rule set and demo trade it for a full sample under real execution conditions, before ever considering a small live allocation.
