For those of you smart/inspired/lucky enough to foresee this moves the rewards are great but for those with "lights out" stories it can be a tough experience.
If you had losses remember that Jesse Livermore made and lost several multimillion-dollar fortunes (billions in today's money) and he was, probably, the best trader that ever lived, one of the first to decipher the language of supply and demand.
Every trader has losses. You can't control what happens with your trade after it's placed but you can control the most important things: your risk, the stop loss and when you chose to trade.
