If I may post a contrasting experience to @yalgaar's...
I am the newest newbie when it comes to options trading. After being a long stock investor for decades, I decided this year, after the crash, to figure out what options could do for me to provide a hedge. I did some free online courses, listened to a lot of podcasts, and then managed to lose thousands of dollars buying puts on a stock in an industry I am intimately familiar with, learning the valuable lesson (again, but with options this time) that the market doesn't care what a fair valuation is, and that it could stay irrational much longer than my options' expiration. I now realize this is a fairly typical entry for many a new options trader. I then sampled a few trade advisory services and then ended up here, intrigued of course by the returns, but also by @Kim's articles here and on Seeking Alpha.
I joined SO in July. Since then I've done 7 trades: 6 official (BYND, UBER1, UBER2, LOW, BBY, BILI) and one unofficial (XLNX). Only one has been a loser (UBER2)
My tips, all of which have been gleaned from advice from members here:
1) As everyone here seems to repeat Ad Nauseum, "Don't chase the entry!" For me, this means that if I can't get in within 2-3% of margin on official, I let it sit. From a post here I learned how to plot the strategy price so I can see it move during the day. I might place a day order for the first day, or even 1-2 days after the official notice, at the official price (or within 3% of margin if it looks like it will not go down), and then I just wait. If it doesn't get filled, I just walk away from the trade. As Kim has pointed out, the prices do sometimes go well below the official.
2) Once I get a fill, I immediately set a GTC close order because I'm on the other side of the world, and I can't be bothered to sit in front of the computer all night. For an earnings trade, if it doesn't get filled prior to the earnings announcement, I would plan on walking up before market close to close it, but I have not had to do that yet. My average GTC target has been around 10% return on risk, but I'm not stuck on that.
Apart from SO, I'm playing with both VolHQ and ChartAffair, and I realize now that I'm going to need OptionNet to visualize potential trades better. I use IB but their option "Performance" visuals are lacking. But that is all I plan on getting. I am now reading books by Wolfinger and Augen, and I'm fully aware that this journey is going to take years. The more I learn, the more I realize how little I know.
My results thus far: for the 6 winning trades I have averaged around 10% (unsurprising I guess given my target, but very surprising to me given that the average time in market was around 3 days per trade), and I lost 0.5% on the one loser. I'm glad to report that my first 2 months have more than paid for my subs! More importantly, I've learned A LOT in just a few weeks, and the curve remains very steep, but here I feel there's a culture of mentorship, something I'm going to need.
