Demo journal versus live journal: what the gap is made of
Posted: Fri Oct 30, 2026 9:35 am
Trading one strategy on a demo and a live account in parallel for a few months, and journaling both, tells you what real money adds to the cost.
What to compare:
Execution. Demo fills tend to be cleaner. Live slippage of a couple of tenths of a pip is common, and that adds up over hundreds of trades.
Hesitation. Even an "automated" system often has a manual step somewhere. With real money people hesitate more, so live misses entries demo takes.
Costs. Some demo accounts show tighter spreads than live, especially in quiet hours.
A worked example: if demo makes 0.20R per trade, live slippage costs 0.03R and missed winners another 0.02R, live is at 0.15R, a quarter lower, with the strategy unchanged.
So demo results are a useful upper bound, not an estimate. Measure your own gap and plan with that discount.
Have others compared demo and live directly? What gap did you see?
What to compare:
- Win rate.
- Average slippage on entries and stops.
- Missed entries, especially where any manual confirmation is involved.
- Net R.
