Is there limit on number of Covered Calls Transactions?

There is no limit on the number of transactions you can perform. Some firms are high frequency traders which use computers to open and close positions possibly thousands of times per day.

There may be some limits, depending on the type of account you have, where the money you receive from closing the position may not be available for use until the next business day, or until the position has settled.

The pattern day trader rule may also apply if you have less than $25,000 of equity in your account and your broker is regulated by FINRA (a US self-regulatory organization - most US firms are).

There is no direct limit on number of transactions you can perform as long as you conform to day trading and settlement rules. Where you may run into a problem is:

• You are trading in a margin account and you violate the Pattern Day Trader rule. This would occur if you did more than 3 day trades in a rolling 5 day business period and did not have $25k of equity in your account.

• It's a cash account and due to T+1 settlement for options, you do not have enough settled cash to transact a BTC
