Open up (revisited)

Okay, so I'm eager to try that ritual where I wait until my stock opens UP by (say) 1%. Then I BUY at the Open (I can do that 'cause my finger is poised over the Buy button.) I stick in a SELL order at 1% higher than the Open. I also stick in a SELL order at 1% below the Open ... just in case the stock don't rise to the occasion. Then I pray. So, in order to convince meself that I got me a good ritual, I try it on historical data since (as everybuddy knows) the future is a replica of the past. Indeed, I try it on one of my favourite coal stocks: 'course, this is fiction ... but great fun, eh? P.S. I include a $10 trading fee, else the 2-year gain would be 236%. I might mention that, sometimes, it ain't that good: and sometimes it's even worser: Note: Wanna see what would have happened with DOW stocks? Click! I might also mention that I ignore the case where the stock drops 1%, then I SELL, then it rises to the occasion. But, as a world famous writer of Science Fiction, I know that I can make anything happen (in my imagination). P.S. I've put in an offer on Gates' mansion.
