What makes a paper trading platform worth using
A simulator only helps if what you practise transfers to a real account. That means real prices, realistic costs and a balance that makes position sizing feel like a decision instead of a game.
- Live or real historical market data, not invented prices.
- Fees and spreads applied to fills, so a strategy that only works for free is exposed early.
- A balance close to what you will really trade. Practising with $1 million teaches nothing about sizing a $5,000 account.
- A journal and a way to review trades. Most of the learning happens after the trade, not during it.
- Chart replay, so you can practise rare setups without waiting weeks for them to appear live.
