Do I have to cancel Exit order from ExitLongLimit() if I need to change the price?

[localappleseed]

I am using ExitLongLimi() with fromEntrySignal provided.

myExitOrder = ExitLongLimit(int barsInProgressIndex, bool isLiveUntilCancelled, int quantity, double limitPrice, string signalName, string fromEntrySignal)

If isLiveUntilCancelled = false, which means this ExitLongLimit only survives for the length of one bar. Then I could repeat to call ExitLongLimit() in each OnBarUpdate().
If isLiveUntilCancelled = true, do I have to cancel this ExitLongLimit() in order to re-submit a new exit with different price?

I printed myExitOrder: no change for the orderId, but price has changed when I call ExitLongLimit() in 2nd time without a cancellation.

Hello localappleseed, thanks for your post.

If you call ExitLongLimit with the same signal name the price of the order will be modified. If it had a different signal name it would submit a completely separate order. We also have the ChangeOrder method:
