Demo versus cent versus tiny live accounts for forward testing
Posted: Sat Oct 31, 2026 7:00 am
Forward testing on a demo account is free, but demo execution is usually better than live. Fills are clean, slippage is small, and rejections are rare. Results often flatter the strategy.
A cent account or a tiny live account runs through real execution and shows actual costs. The money at stake is small, and the psychological pressure is partial but real.
For scalpers, live testing with minimum size is the only way to see the true effect of spreads, slippage, and rejections. Even a few hundred trades at micro size provide a much better picture than a demo run.
Some brokers treat demo and live differently in terms of liquidity and latency. A strategy that appears profitable on demo might lose on live due to those differences.
The progression from backtest to demo to micro live to full size takes time, but each stage filters out weak ideas at lower cost.
What was the biggest difference between demo and live results for the same strategy?
