|---|
| Simulated fill models (AtMidPrice/AtBidAsk) | Not applicable | Live uses broker executions; paper trading uses user-entered fills. See Settings. |
| Simulated slippage | Not applicable | Live executions reflect actual fills; MesoLive does not apply a simulated slippage model. |
| Simulated commission models | Not applicable | Live uses broker commissions; paper trading commission is configured per paper account. |
What replaces this in MesoLive
- Live accounts: orders are sent to the broker; fills/partials are reflected from broker executions.
