It is one of those trades where everyone has the same position, the news comes out and then...
...drum roll...
... it goes the opposite way before it plays out.
Get yourself a job as a trader and milk the traders option. That way you also learn about the markets and executing trades. If this is nothing for you quit, else you earn and then at some point you go on your own (THIS IS A FREE CALL FOR YOU).
This assumes complete information about future trading is contained in your past track record. Say if you have a massive-fuckup-potential then the formulas dont hold.
I had something kind of similar. Nearly all big losses due to bad trades gone bad were happening late on Thursdays or on Fridays. I resolved it by taking Wednesdays off and being mentally fresh on Thursdays and Fridays.
