BMY -7%

Daily setup: Gap up on news, into resistance, fade from premkt
Entry/play: tested high, few min base, shorted breakdown
Management: Initial stop above day high. Then trailed stop. I considered stop of .86 or .93. The .93 would have kept me in, but that gets back to picking good stops and honoring them. .86 seemed like a good point bc the level2 I watched for entry. 
Psychology: Why short a gap up? I'll allow that for gaps into resistance and weak market conditions.
Later, after a struggle, this broke down like I hoped. But I traded the plan and that was the exercise of the day. 
Take the small losses according to rules bc yanking stops is more harmful overall

TSLA -9%

Daily setup: Gap up, but looking for a fade. Market gapping up, but so technically damaged from Friday that I don't think the gap up will be for upside.
Entry/play: waited for upside failure, then short via long put
Management: trailed stop. stopped out. 
Psychology: I came in today bummed about last week's wipeout. There were no good setups, or at least none of my standard setups. So I stabbed at this one with small size. Should have gone for a walk. 

Lesson: when it's not my setup, I shouldn't expect it to play out in my "usual" way. I am not an expert in this setup.

Bouncing back

The end of last week was a disaster in which I yanked a stop and I suffered the well-known cascade of terrible events. I'm still reeling.

It is much better to take a stop than to suffer the worst. It is RARE that stops don't save me from disaster, so I need to set my ultimate stop and never touch it.

Something else to consider is on Thursdays and Fridays if I should trade same week or next week expirations. When I'm right it's so good, when I misbehave it's so bad.

I am considering paper trading today, but know I won't. I'm still wounded, even after the weekend. But with the lesson fresh, I will NOT yank stops.
