Hi all. I haven't been this frustrated in a long time. I've been doing this shit for a long time (August was my 25th anniversary), and I've done very well. My best strategies have been automated mean reversion (haven't done this in a long time) and systematic momentum trading based on relative strength and weakness, and very simple S/R and tech analysis. (This is what I still do, and it's actually very fun and profitable.) First of all, what did I lose today to satisfy everyone's curiosity? 130 bucks. That's it. A molecule in the bucket. But I feel like I left a gallon on the table. I worked out yesterday, slept great, ate well, and sat down at my desk with a great and relaxed attitude at 6:00 CDT. (2 and a half hours before the open, for those of you over seas.) I thought it was going to be a great day because of the volatility pre-market. So, what is the source of my frustration? I traded like an absolute idiot right out of the gate. One of my rules is "If you miss the first one, don't take the second one". I missed the first bid at 210 on BA off the open for a quick huge probability scalp, and took the second one a couple of minutes later and it blew right threw me. Luckily, I only took a 40 cent hit, because I knew I was an idiot. Of course, I should've been looking at pre market support. Wasn't doing that. The second was in ASAN. Same rule. I missed the break of 114, so I offered the short when it came back up to it. (This is actually a very good strategy IF a lot of volume has occurred at that price. It hadn't. Ironically, one of my favorite trades is a failed support break and buying when it comes back up through. Didn't do that either). Again, I took a 60 cent loss because I knew I was trading like a moron. It went up to 117 in the next 10 minutes. I tried not to trade my P/L and scalped my way back, trading very small to manage risk, to a "reasonable psychological tolerance". (I made that up, and it's a bad thing to aim for, but it's what I was after today). I know how to do this well, but there are better opportunities out there every day. And I'm too old to do that shit all day every day. I was exhausted. Then I brought up an old window on my scanner in the last half hour for some reason and tried and old volume spike mean reversion play. (This can also be a great strategy if you do it right). Bought GREE just above 31.50. Thank goodness I was still trading small. I'll look back at this and laugh, but only because the losses are so small because I managed my risk based on knowing how badly I was trading. Tomorrow is another day. New Guys: Knowing what to do and how to do it is not enough. You've probably read it in a few books, but knowing yourself is paramount to success in this business. You need to know when to push and when to pull back, regardless of how those around you are doing. Experienced guys: This is my first "opportunity cost" related frustrating day in quite a while. How often do you have these? Sorry for the novel, Brandon. Thanks for any responses.
