1. When you get a very huge move with a stock that doesn't have any good news, you're going to get a big crash.
2. If you're dip buying after a huge fast crash, you have to understand that a bounce will be just as fast. And you gotta know that if it doesn't bounce, you get out immediately.
3. If you want a perfect dip buy, it has to be an earnings winner that drops to support, not just a random stock soaring.
4. On biotechs when you see big gap downs in a recent past, go and see what news it was, because there has been other biotechs that crash on drug failure and then spike again on doing some further analysis.
5. When you see a claim hat a common drug or vitamin "kills cancer cells in a petri dish", keep in mind : so does a handgun. ( So does gasoline and bleach)
6. Different setups are worth different size.
7. Wait for pullbacks to cover your short.
8. If you have a strong opinion about stock - go ahead and trade it then, but otherwise don't let your opinion be guided by what the stock is doing.
9. When you have a double top midday, it's a potential short. But it has to be a spike into further resistance.  If a stock is slowly grinding, it is more likely to break out. A spike that ends in a double top - that's good.
10. Any time you have big oil disruptions, it's going to reduce supply and affect global oil price.
11. After double top, the more times you get a stock to test its resistance level, the better the chance that it breaks.
12. Chart premarket doesn't matter that much, because it has such a low volume compared to what it gets like at the open.
