Cannot be done precisely, on average, closest you will get is about 3% of the price. Only thing which can be predicted is the time when price will stop trending or reverse .
Price cannot be predicted accurately for the simple reason that the actions of people, who ultimately control price, are not themselves predictable. Most rules have exceptions, and here is the exception for this rule. Sometimes people's behavior CAN be predicted, once there is a trigger. One would be pretty silly to "predict" that a fire is going to be started at such and such a time in a theater, but I WOULD predict that IF a fire started in a theater, most of the people there would get the &$&% out.

As for the market, predicting that XX stock will be XX price in XXX days/months is silly. No one knows what is going to happen in the near future. But if a stock gaps up because of great earnings, and then does the unlikely thing and go immediately back down, it would not be foolish to ascertain that the stock is probably going to keep going down because the buyers are now "trapped" and going to want to get the &$&% out. The best moves are fueled by emotion, not by logical "prediction." That is why the academics--and I am one myself--often get the market wrong when they say that the market is "efficient" and, therefore, no one can in the long run succeed in beating it. The market is efficient most of the time, obviously. Perhaps it is "efficient" 99% of the time. But it is in that 1%, the sweet spot of the markets, that contain the opportunities to succeed.
I am not going to tell you how I do it but take a look at DJI about 10:45 and then 15:10 eastern time tomorrow.
Not even a hint? I was gonna take tommorrow off because of shit I went thru with my trading platform this morning. I guess I am back in. How far off can you project?
Prices can be predicted whenever the market behaves in a predictable fashion. When news shock the markets, as news are not predictable, prices aren't. When there are no much impact of news, market prices can be predicted with high degree of accuracy. Here some examples: http://www.tradingpro.com/PastperformanceDJIA.html You will see a lot of days where the market can be predicted up to a reasonable degree as to generate profitable trades. Of course you will not get that service for free. They will require some money from your own pocket.
If we could predict, how would we trade with one another? Walther has more money than Bill Gates as he has been predicting and compounding here for ages. It is Rumored that HarryTrader is going to buy France s soon as he gets Franz out of Jail.
I remember when I was a kid, I read something about two ancient Chinese philosophers discussing whether the key to immortality was lost due to a certain person's passing. One philosopher said that particular person cannot possibly hold the key to immortality because if he did, he wouldn't have died. But the second philosopher said that might not be true because he might have failed to carry it out.
