Frequently Asked Questions
1. What is a day trader?
The NASD and NYSE define a Pattern Day Trader (PDT) as one who effects 4 or more day trades (same day opening and closing of a given equity security ("stock") or equity option) within a 5 business day period.
Please note that Futures contracts, Futures Options and Single Stock Futures are not included in the SEC Day Trade rule.
2. What is the definition of a "Potential Pattern Day Trader"?
A potential pattern day trader error message means that an account has less than the SEC required $25,000 minimum equity with loan value AND the number of available day trades (3) has already been used within the last 5 days.
The IB system is programmed to prohibit any further trades to be initiated in the account, regardless of the intent to day trade that position or not. The IB system is programmed to protect the accounts with less than $25,000 so the account would not âpotentiallyâ be flagged as a day trading account.
Please note that if an account receives the error message âpotential pattern day traderâ, there is no PDT flag to remove. The account holder will need to wait for the 5-day period to end before any new positions can be initiated in the account.
