Buying a cBot because the equity curve screenshot looked smooth is how accounts die quietly. cTrader gives you a proper Strategy Tester — use it before you spend €40 or €400.
Get the file the right way
Legitimate sellers deliver a .algo or compiled cBot you import via Automate. On AlgoScriptX you download after checkout; trials may give you a time-boxed license. Never run a cBot sent as a random ZIP from Telegram.
Strategy Tester settings that matter
Open Automate → select the cBot → Backtesting. Match these to how you actually trade:
- Symbol — EURUSD is not XAUUSD. Test the pair the seller documents.
- Timeframe — A scalper on H1 stats will lie on M5.
- Spread — Fixed minimum spread is optimistic; variable spread hurts grid and scalping bots hardest.
- Commission — Add what your broker charges. Prop firm rules often differ from retail.
- Date range — At least 12 months, ideally through a volatile period (2022–2024 had plenty).
Run twice: once on demo spread, once pessimistic. If profit disappears on the second run, you learned something cheap.
Stats worth reading (and one to ignore)
Profit factor above 1.2 over a long sample is a conversation starter, not proof. Max drawdown relative to account size matters more for prop rules. Win rate alone is useless — a 85% win rate with huge losers is still a blow-up bot.
Sellers on AlgoScriptX can publish backtest fields on their listing. Compare those numbers to your own tester run. If they diverge wildly, ask why before you activate a license.
