If your broker does not allow you to short options, such as selling puts, you can still do the "equivalent" of selling a put by initiaing a "buy/write" strategy.
(That being.... simultaneously buying a stock and selling a covered call.)
Thus, just like selling a put, you still get to select your strike, your % otm, your credit, ect.....
And the order will NOT be filled unless all the criteria you desire are met.
That being, strike, credit, date....
However, since this will be a buy/write and not a put, you will place the order as a debit instead of a credit.
You will need your broker to go through the set up with you a couple of times, to be sure you are doing it correctly.
But once you get the hang of setting up the oder, you will realize the end result is the equivalent of selling a put.
And the nice thing is, you will be given permission to initiate buy/write trades with no problem.
If the idea interests you, feel free to ask questions about it here.
