The “Pattern Day Trading” (PDT) rule is only applicable to the US market. The Singapore and Hong Kong markets do not follow any PDT rule. 

The PDT rule states that the customer should not execute four or more "day trades" within a rolling 5-Business Day period. By default, the fourth pattern day trade will be blocked to avoid PDT violation. A day trade is considered the opening and closing of the same position within the same day.

FINRA rules define a “pattern day trader” as any customer who executes four or more “day trades” within five business days, provided that the number of day trades represents more than 6% of the customer’s total trades in the account for that same five business day period.

Your day trade count includes pending orders that you have placed. For example, if you’ve purchased a stock and then set a sell limit order on that same stock on the same day, that order will count as a day trade in our system, regardless of whether or not it gets executed. However, if the trade is not executed on the same day, it won’t be counted as a day trade for regulatory purposes, and your day trade count will be reset on the next day.

What is “good faith violation” and how does it affect me?

A good faith violation occurs when you buy a security and sell it before paying for the initial purchase in full with settled funds. Only cash or the sales proceeds of fully paid-for assets qualify as "settled funds".

Liquidating a position before it was ever paid for with settled funds is considered a "good faith violation" because no good faith effort was made to deposit additional cash into the account prior to the settlement date.

If you incur 3 good faith violations in a 12-month period, we will restrict your account. This means you will only be able to buy assets if you have sufficient settled cash in the account prior to placing a trade. This restriction will be effective for 90 calendar days.
