I use TDI in conjunction with ichimoku clouds, and will not make a position trade no matter what the TDI is telling me, if the price is in the clouds. I wait for a breakout, and then when the mid channel keltners are spread way apart, and the TDI confirms a bottom or top, then I go in the opposite direction from the trend. And really love it when the TDI is pinching and offset on the parameters either high, or low.
Kind of a complicated system, but it really nails big trend reversals. Sometimes have to wait one or two days for them to develop, but the rewards are worth it. I mostly use it on the dollar/franc.
