There are no specific restrictions on the amount of investment orders you can start.
However, it's crucial to be aware of a limitation related to "day trading" of stocks, as mandated by US regulators, specifically the Financial Industry Regulatory Authority (FINRA).
This restriction is in place to discourage excessive trading practices and is enforced when there's evidence that a customer qualifies as a Pattern Day Trader (PDT).
A "day trade" refers to buying and then selling (or selling and then buying) the same stocks within a single trading session.
If your account activity is identified as Pattern Day Trading by the brokerage firm we use for buying and selling US stocks on your behalf, certain restrictions may be applied to your trading for up to 90 days.
We will make efforts to inform you if your trading behavior might trigger this restriction. However, we strongly advise all customers to avoid engaging in Pattern Day Trading to prevent any inconveniences.
