A common story: a trader practises gold scalping on a demo for two months, sees consistent profits, opens a live account, and results collapse. Part of the reason is often the spread.

How demo and live can differ:
- Demo accounts may use a simplified feed with consistently tight spreads.
- Demo fills are typically instant at the quoted price. Live fills face real liquidity.
- Spread widening during news may be smaller on demo.
- Some brokers use the same feed for both, but execution logic differs.

What to do before trusting demo results on gold:

1. Compare demo and live spreads side by side for a week, at the same times.
2. Add a realistic slippage assumption to demo results, e.g. 10–20 cents per trade on gold.
3. Run the strategy live at minimum size for a month before scaling.
4. Track the difference between demo and live results trade by trade.

Demo is useful for learning platform mechanics and testing ideas. It's not reliable for measuring the true cost of trading gold.

How big was the gap between your demo and live gold results?

Judging a live account from the spreads seen on a broker's demo server is a bad habit. The two servers are separate environments, and nothing obliges them to match.

Demo servers often run on a simplified feed. The spread may be a fixed or smoothed figure, or it may stay narrower during rollover and news, because there is no liquidity provider behind it widening in response. Live spreads, especially on variable accounts, stretch when liquidity thins, and that is exactly when many scalpers are most active.

The reverse can also happen. Some demo feeds widen artificially or lag, which makes a live account look better than it was expected to. Neither direction is reliable, which is the whole point.

What gets compared matters too. A demo account type may not map cleanly to a specific live account type. A demo copy of a raw spread account may not include the commission, making the headline spread look better than the true cost.

A more useful approach is to log the live spread at the moments that matter: the second a signal fires, during the open, around rollover, and near news. A week of that tells more than any demo comparison, since the average spread is rarely the spread actually paid at entry.

Time of day matters as well. Spreads around the daily rollover can balloon on many servers, and a strategy that trades through it pays that cost whether or not the demo showed it.

Does the live spread at entry usually match what demo showed on the same pair, or does the difference only appear at certain hours?
