From 50/50 (it could swing either way and you can have zero knowledge on which way it'll swing), to %1-100 being able to know before hand, how much can you know?
What causes prices to go up? What causes them to go down? Obviously, no one knows for certain when it would happened, but has there been a consistent "pattern" lately? When prices have gone down, have you known to a reasonable degree than they would bounce back up? How?
The market is very volatile and unpredictable, no matter the amount of indicators you make use of they can't still tell the future, they can only help you know whee the market is heading, no technical analysis is 100% correct, that's why you see even prefessional traders have losing trades, prices go up when there are goodnews and vice versa for price going down, that's why you need both technical analysis and fundamental to predict market movements.
