This morning Jeff Bailey fit a retracement bracket to the S&P 100 Index (OEX.X) to a "level within a level" to get a better idea of where short-term support and resistance levels may be. I'm going to shamelessly steal from him and do the same thing with the Biotechnology (BTK.X) index.

As you can see the retracement bracket based on the April 2000 low and the September 2000 high doesn't help a short-term trader identify potential risk reward levels very well. Fitting a retracement bracket to the February 16, 2000 high of 628, and looking at a 60-minute chart gives us a better perspective of where some near-term resistance levels lie.
Biotechnology Index Chart - 60-minute interval
The 60-minute chart shows that we are currently approaching a short-term resistance level at 476 (the 38.2% bracket and 1/8/01 low). You may say that is all fine and dandy, but the bracket still doesn't give me a support level. That is true. The retracement bracket is just one tool in the technical toolbox. In this situation I would break out one of two technical tools. The first is the gap that formed at the open today, 447. A lower risk support point would be the 50-period moving average at 460. Either one of these should represent a support level in the 447- 460 level depending on your risk. With BTK currently trading around 469, 9-22 points is a decent amount of "heat" to take on a long play with a potential gain of 8 (the 38.2% retracement bracket). I would like to see prices come back a little to improve my risk\reward, or if prices can close above the 476 level (38.2% retracement bracket), we'll have a new level of short-term support and some lower risk.
