I use a moving average of the russell cumulative tick ($tikrlc in TS), since it encompasses more stocks, and small cap stocks are usually a good barometer of strength/weakness in the market. I also have been watching $VOLRLDC which is advancing minus declining volume in the russell.
The russell cumulative tick gave a great early warning signal today. I take a moving average of it.
On the daily chart the trin and trinq are very helpful
