I don't think you can increase your percentages of guessing correctly. It's always a 50/50 proposition. Keep in mind tho that I'm talking about from one day to the next. And I'm not saying that there's no purpose in charting. But I am saying that a long term trade starts off as a short term trade, and anything can happen. If you're trying to catch a trend, then a certain amount of "luck" is necessary. And if luck is a component of your trading plan....well for a few it might work, but for most ? Not likely.
