The TICK/TRIN symbols are going to be specific for your data source. I use E*Trade, and there symbols are $TICK and $TRIN. You will have to look it up for your data provider.
To add it in QT, you need to right click on the top of the indices bar and add it to your list by clicking on Edit Indices. Once you do that, you can double click on the TRIN and TICK symbols in the indices bar and a chart should pop up. Unless you have a backfill data source setup, the chart will probably be empty. I own the unregistered version of QT, so it only stores 2 days worth of data. Registered version will hold 10 days, I think.
My TRIN chart is a Consolidated type chart, 1 min/ 4 hour view. Add a 50 period EMA. When above this, bearish, below it, bullish. You can use some trendlines as well. Also look for sharp moves one direction or another. This usually indicates a change in trend. Also look for some consolidation patterns (short moves up and down, while price moves the opposite direct of the current trend). For example, the price is moving down, and it starts to bounce. Look to see what the TRIN does. If price continues to move up, but the TRIN just moves back and forth a little, odds are price will continue down.
The TICK chart is a bar chart, 1 min / 4 hour view. Then add a MACD(19,39,9) with no histogram. This is a quasi intraday McClellan Osc, described by Tom McClellan here:
This is good at finding oversold and overbought levels. If price is moving down, and the MACD is getting to the -80 level or lower, look for a bounce. Opposite is true for a up move. Also look at the spikes in the TICK. If you eyeball deeper negative tick spikes than positive, generally things are negative.
The above is assuming you are looking at the NYSE or the SPX. If you are looking at the COMPQ or the NDX/Q's, you will want to use the TRINQ and the TICKQ.
Hope this helps. If you need more information on setting this up, let me know.
