My crude understanding of tick and trin is that they are like parts of the weather report.
Kind of like the way humidity and barometric pressure can tell you if it is going to rain.
TICK = the number of stocks ticking up minus the number of stocks ticking down. Any number over zero means the TICK is positive. When it gets too high [over 900-1000] it will pull back and will usually reverse.
TRIN = Measures volatility - has inverse relationship to the TICK
Low TRIN is bullish
When advancing stocks dominate volume flow, the number reads under 1.0
When declining stocks dominate volume flow, the number is over 1.0
Like I said I'm just learning this stuff so, If any of this is misstated
Please correct dna
TRIN indicates bullish sentiment. Below 1 means bullish. Above 1.20 is bearish. If TRIN gets extremely bearish, a trend reversal is near. TICK is the number of stocks advancing/declining.
