Another Crash Immanent?

I noticed that the current rally in the S&P 500 shares fractal like similarities to the pre-crash market. Running through some trendline analysis with support becoming resistance on both the pre-crash and post crash rally it appears that we could see a similar February like crash coming to the new rally. Obviously markets aren't always the same but there is a great deal of symmetry throughout the market, in patterns like head and shoulders for instance. Something to watch out for as the market gives us more clarity in the next few days. Who can honestly say the current rally is representative of the fundamentals in the real economy right now? Another crash might be unavoidable.
