There are no mistakes only lessons.  Well, I learned some really good lessons.  I had bought $DUST at $6.35 on 2/9/16. On 2/10/16, when I awoke then next morning it was at $8 and falling.  Although it was premarket, I had that take profits mantra going through my head.  I was expecting a morning spike and my instinct said to wait for the morning spike, but I didn't listen. I tried to sell and missed, I tried again and missed, finally I set a price of $7.55 which was 10 cents below the current.  SOLD $7.55.  the price was at $7.65, but sold mine at $7.55 then continued right at $7.65. AND of course went up right away. By market open, it was back down to just below my sell price and yes the morning spike happened.  So for the next 2 hours, I berated myself, for being sooo stupid. So what did I do next?  I did something even worse.  My instinct said the price was going down.  The charts said the price was going down.  I even knew it was going to be hitting the low around 1:30.  So what did I do?  I bought at $7.69 at the first green up tick at 12:38.  Then I watched it fall.  Yes, I just watched.   Did I cut losses? Hell NO! that would have wasted a day trade. Besides I knew it would go back up eventually.   Then the price consolidated. Here I thought was the new bottom.  So I should buy here.  It was like I totally forgot that I bought earlier and was holding a loss.  I bought at $7.34.  And watched it continue down.  Then the truly stupid came out.  The price had gone back up to $7.40.  I sold 200 of the 2000 shares I had.  I still have no idea why only 200.  It wasn't a typo.  I had it in my mind that I needed to sell 200 shares and I did.  The thought of "the price will go back up" was running my mind.  The thought of cut losses quickly was being pushed aside.  I saw the price at the end of the day was $6.99.  "It will go back up, don't worry" the dominating thought in my head said. Only to wake the next day with the price at $5.50.  I was over $4,000 in the hole.  My biggest loss to date.  I still haven't sold.  I was unable to do anything yesterday but worry.

Lesson 1: Listen to your instincts

Lesson 2: Cut Losses quickly (To hell with a Day trade)

Lesson 3: Don't add to a bad situation

Lesson 4: Know exactly what you are doing and why

Lesson 5: (for everyone else) Do as I say, Don't do as I do. Learn from my mistakes, so you don't make the same ones.
