If you're looking for the absolute bottom of Capitulation, then you need to look at very small time frames, perhaps 5 min IMO...and look for some kind of bottom to form, the same way you would on any other time frame. Look for the usual suspects like tweezer bottoms, double bottoms, or some kind of trading range where there is a clear break one way or the other, and if its a break to the upside, then go long with a stop either under the trading range (if its tight enough)or under the broken resistance level with enough room for the stock to breath.
Look for increased volume in this lower time frame as it MAY indicate the final surge and ultimately the exhaustion of panic selling. That doesnt mean you should buy after you see a bar with volume like that, it just means be ready because the reversal may be close.
