China,
"Biggest blunder one can make"....
. Don't you sit on the fence now...
Well like most things if you look at 'em long and hard enough they tell you a story. Zero TICK bounces are as good now as they ever were as are some of the more basic TICK rules. You're right in one respect, i.e. fading tick extremes or tick/price divs can be hard work these days (although that's probably more to do with me being tired of that type of trading). Still, like I said, always prepared to learn something new so I'll have a look a this momentum idea.
Stoploss,
Was always going to be that kind of day in fairness.
The wonders of TRIN eh? A good day for illustrating the point we were discussing though, so I'm kind of glad it came up. The reason the TRIN was "bitty" today is because of the underlying. Bit difficult for me to analyse preperly because MyCrap doesn't have decent volume data. However looking elsewhere for the info, TRIN was showing a fairly lacklustre underlying with advancers only just outnumbering decliners for most of the day (3:2) and likewise with regards to volume.
So, given that we said that it's the "velocity" and direction of TRIN that matter, the fact that you had to reduce your timeframe to get any kind of idea on TRIN movement probably signals thats it's time to stand aside.
Given the likelihood for this kind of day, for me there were were a couple of trades in the first 90 minutes. 1 in the last 90 minutes and the TICK climax fade off the pivot at 13:15.
TICK (on a more basic level than China's observations) showed the same thing as TRIN for most of the day once the first hour was out of the way, i.e. there just wasn't the necessary weakness in the cash to support a serious challenge on YD low and take it out.
There was certainly more to be extracted from the day for the young and nimble. But, once again, as China quite rightly says, the nature of TRIN just isn't going to support this approach.
As you seem to be discovering though, TRIN can be useful, providing you don't expect to catch every single move the day has to offer.
I actually watched TRIN (for the first time in three years....) today just for interest. It was enough to remind myself of why I don't use it any more. Futures led TRIN significantly on every (and I mean every) single move today. And as you noticed, there were a couple of "false" TRIN moves as well, the worst of which was at 13:30 when the move on TRIN falsely indicated a move up through the pivot on the futures (in fairness it reversed the bar afterwards).
