Using Technical Analysis, When Should You Take Profits When There's No Overhead Resistance?

What are some technical analysis techniques for setting an exit when there's no recent overhead resistance?

For example, imagine a break out to a higher price than has been seen in four years. How would you decide when to get out? What technical factors would you take into consideration? Would you look at past spikes to try to gauge where the top may be? Would you look at the resistance from four years ago? Would you start scaling out at the first dip and/or a second confirming dip?

Thanks in advance for any input
