Good advice and 100% correct on the confirmation, which most people leave out. A double top is not a double top, until that low is broken! However, you could always go aggressive and try to short around this point, which may have a lower chance of a successful trade than waiting for confirmation, but there's good risk to reward. If it breaks and closes at new highs, cover and wait for another signal. If it does in fact confirm the double top, you're sitting pretty with a beautiful entry near the absolute top. This site has been helpful for me with chart patterns like double tops and other analysis methods, lots of good reading material if anyone is interested.
