Support and resistance + upcoming crash


hI i try and try charting but support and resistance lines don;t seem to work no matter what I do.
I don't know how to use it, and BTW the rally has been going on for a sixth consecutive week, the consensus among my broker + many on cnbc and bloomberg is that the market is overheated as a bear market rally.

It seems like a crash is imminent?

yesterday the Dow NASDAQ and sp500 posted the largest single day drops!
my bad, they now say it's a severe correction
Professional market analysts I follow suggest a scenario where the S&P 500 is currently retracing a portion of the recent rally off the march lows which they expect will form a higher low (in the mid-low 800's) by mid to late May. They suggest this higher low will then be followed by a or higher high (above 930) in the mid-July time frame. In Elliott wave terms forming a simple ABC corrective retracement within the secular bear market. The mid-July ABC peak would then be followed by a more significant price decline into the late fall (Oct-Nov 2009) time frame.
