Demo vs live accounts

A demo account is the closest thing to a free trial in trading. It connects to live market data but settles trades against simulated cash. For learning the platform mechanics — placing orders, setting stops, navigating the dashboard — a demo is essentially perfect.

For learning trading itself, a demo is partial. Three things differ silently between demo and live. Execution is usually instant on demo and lossless on slippage; in live markets, large or fast orders move the price against you. Psychology is the second gap: you will hesitate, freeze or overtrade in ways you never would when no money is at stake. The third gap is broker-side latency and partial fills, which most demo engines smooth over.

A useful protocol is to spend two to four weeks on demo establishing two things: that you can operate the platform without errors, and that your strategy produces results consistent with its specification. Then bridge to live with the smallest position size the broker permits — often a £10–£50 round-trip. Survive that for two more weeks before scaling up.

Apply exactly the same protocol to AI bots. Run any signal service or automated bot in paper-trading mode for at least one full month, and compare its live-shadowed P&L to its claimed performance. If the gap is more than a few per cent, the marketing material was optimistic.

The single most common mistake is to treat demo profits as predictive of live profits. They are not. A profitable demo is a necessary but insufficient condition for a profitable live account.
