In "A Beginner's Guide to Day Trading Online", Toni Turner suggests using the Tick and Trin in combination with the following signals: Tick > +1000 - market is over bought and MAY pull back. Tick > 0 <1000 - go long. Tick < 0 >-1000 - go short. Tick < -1000 - market is oversold and MAY reverse. Trin > 1.5 - market MAY reverse back to bullish. Trin 1.5 to 1.01 - go short. Trin 1.00 to 0.90 - avoid. Whip zone. triin < 0.9 > 0.4 - go long trin < 0.4 - market MAY reverse back to bearishness. Her book is copyrighted 2000. Question: Are these parameters are still reasonable in the current market? What opinions do you have of this scheme? I am using this right now, but its only affect seems to be to keep me out of most trades. Maybe that's a good thing.
