When you place trades through Tradester, the orders are mirrored across your linked accounts. The actual order routing and execution are handled by your trade host (for example, Rithmic or your broker).

Because of this, you may sometimes see small differences in fills (slippage) between the main account and the copied accounts. This is normal across all trading platforms and is part of how orders are executed at the exchange level. In most cases, the differences are minimal.
