Here's a link about pattern day trader status:

Excerpt: "Pattern Day Trading rules only apply to margin accounts; a customer trading in only a cash account will not be designated as a Pattern Day Trader...Please note that there is no limit on Day Trades in a cash account."
(What is the "catch"? You must wait 3-4 days for funds to settle after you liquidate a position.)
If you have a cash account, they say, you cannot
ever get pattern day trader status; that only comes with a margin account;
BUT,
you have to wait 3 days for your funds to become available again after you sell a position; if you used only 1/4 of your cash each day for one day trade, you could day trade once every day; if you used only 1/8 of your cash each trade, you could make 2 day trades each day.
IF you had $10k in a cash account,
theoretically, you could make one $2,500 day trade every open market day, and never get the PDT status; or, you could make ten $1000 day trades spaced evenly over every 3-4 days.
Basically, it is impossible to get pattern day trader status with a cash account (with ALL brokerages???)...but you get no margin and must wait 3-4 days for the funds to settle after each sale.
