If a cash account customer is approved for options trading, the customer may also purchase options, write covered calls, and cash covered puts. Short selling, uncovered option writing, option spreads, and pattern day-trading strategies all require extension of credit under the terms of a margin account and such transactions are not permitted in a cash account.
