Yesterday I bought weekly 195 puts at $2.56 and sold them for $4.40. I held a few contracts overnight and sold them this morning for $8.00.
I primarily use weekly options. When I feel highly confident about a trade, I am willing to hold overnight, despite theta loss. To counter the higher risk, I usually hold overnight on Monday or Tuesday and only for one night, and it will be a small amount of capital. Also I have to be ready (mentally) the next day with my exit plan.
In this example, when the price dropped at open, I decided to take advantage of any IV increase and sell the rest of my puts. I needed to be aware that the daily trend is still up, and the stock can bounce of 20sma back up towards 10sma.
Now I can use 30 min and daily chart to buy puts again, because I expect more downside as per weekly chart.
