Pattern Day Trader (PDT) Rule
The Formal Definition
A FINRA regulatory rule classifying any margin account that executes four or more day trades within five rolling business days as a Pattern Day Trader, requiring a minimum equity balance of $25,000.
PDT Requirement: Minimum Account Equity ≥ $25,000
Cole Barrett's Reality Check
The Unvarnished Bottom Line"The PDT rule is Wall Street's velvet rope. If your margin account balance drops below $25,000, FINRA locks your account from opening new day trades for 90 days. It was designed to protect retail traders, but mostly it traps undercapitalized accounts."
