Are swaps and commissions included in backtest?

Don't know about all brokers, but every one I've used, the tester has simulated commission and/or swap.

However, do not count on OrderCommission and OrderSwap. Some brokers don't use those fields. (Maybe related to Government required accounting/tax laws.)

If I understood your question correctly:

In MT4 (MQL4) during backtesting:

  • Only the spread can be changed.
  • Commission and swap cannot be adjusted in the Strategy Tester and are not reflected automatically.

In MQL5 (MT5):

  • The Strategy Tester is much more advanced.
  • You can directly adjust spread, swap, commission, and even slippage, making backtests much more realistic.
  • Equity graphs and reports accurately reflect all costs.
