## Capital Injection

A capital injection is a significant addition of funds to an account to improve its financial health or to expand its capacity. This is often necessary when an account is under-collateralized or when the investor wants to increase their leverage.

It is a direct and effective way to restore margin compliance or to scale up trading activities.
