Conventional trendline study.

Using the conventional channel on the $NDX, I took a linear and logarithmic regression of the points on the Stockcharts snapshot of the $NDX. The days I used have a vertical blue dash under them.

Using the three (what I regard as) potential turn dates, the lower price channel targets are as follows: (Linear regression, then Log regression)

7/17/08 1716.7 1723.3
7/18/08 1710.8 1717.9
7/21/08 1693.0 1701.8

This is probably the range of prices the bottom will be found in...

I would also add that the weekly Bollinger Bands, next week, should also give us a clue as to the price level of the bottom...
