What sign should I look for that indicates a reversal???

I'm sure this thread is relevent in the type of market we are in now, especially when it comes to the yen pairs. For those of you who have the experience, please weigh in with your opinion on this subject.

I've been using a 15,3,3 slow stoch for years. Works great about 70% of the time.

for an indication of a trend reversal, you have to adress a certain timeframe first, cause the same market can be on opposing trends on different timeframes

example usdyen


weekly...up
daily...up
1h...down
5min...down (1.30 pm)

on 5min, you may witness a trend reversal form down to up over the next couple of hours..
