Target Stocks

How does one decide the time factor to hit target in Technical Analysis of stocks?
There are various studies available in T.A. softwares to anticipate trend reversals / continuations. I am however not certain how the time to hit target is judged?
You should be very cautious with all this technical analysis stuff. I saw a website which is starting to address historical data in a much more interesting way. Maybe you should check it out, although it is still in test phase. It is www.abunova.com
