Over-leveraging refers to excessive leverage that brings the account's Margin Level to 150% or lower. This can significantly increase the risk of large losses, especially during high-impact news events.
This typically involves taking on a trade (or multiple positions at the same time) on a single Symbol or Instrument that is too large, surpassing the leverage limits set by CTI, causing an account to reach a Margin Call.
Such practices can lead to rapid account depletion, and are generally not allowed to maintain responsible risk management.
