Quote from barrytaylor:
I use the TRIN for intra-day and end-of-day trading. A couple of things that might help:
1. Using a 13 day ema in my experience is too long, try using 5 to 10 to highlight market cycles
2. When calculating averages remember the TRIN is a ratio - 1 is netural, 2 and 0.5 are equivalent. You have to adjust for this using the Log function.
3. Look for divergence patterns in the TRIN - market is down (close less than open) but TRIN shows buying
