Copilink depends on the PnL and account updates that NinjaTrader receives from the broker/data connection.

Rithmic PnL updates are slower than Tradovate, so risk rules based on PnL/equity, such as daily loss limits, daily goals, account goals, and trailing drawdown, can trigger later on Rithmic.

For Rithmic accounts, use a small safety buffer on limits and goals instead of setting them exactly at the prop firm threshold.
