hi RSprengers. I use one of the introducing brokers of SLK so I use REDI. Using the SP as a short term indicator I buy the put when I think the stock is going lower then buy the stock. I do the put first coz it is harder to put on than stock. If you buy the stock and it prints 5 cents lower, xometimes the market makers adjust right away AND they adjust way too much when they see the quote size favors further donw move so you are really stuck, you'd end up paying 20 cents against you just to stop the bleeding. After I buy the put, I try to buy the stock on the bid.. hopefully SP keeps going down, then I adjust my bid lower,etc. When do I sell the call, depends on the delta of the call the exp date, the way the chart looks. At this point it becomes a market call, either I am right and hit a home run when I sell the call 1-2 weeks later or I eat the 30-80 cent loss being long the synthetic call. Hope this helps.
