Cycle indicators

Are there any indicators/tools/methods for determining cycles?

I am interested in finding daily cycles and also finding cycles on shorter time frames as well.

As a side note:Does anyone know of certain times of the day when price is likely to reverse its direction?

thank you

Price Reversal

Just my 1 Cent -

As far as I know the price reversals usually happen at the Start or the first 2-3 hours of start of the London trading time - which for the US is between 3 and 5 AM.

Market reversals

The most consistant time for reversals is when the European Market closes down a few hours after the US Market opens. Look thru your charts and the evidence will be in front of you.
