Great indicator for Takeprofit point/ trend is over?

 
Which indicator is good in showing when to take profit / when the trend is over?

Hope for help.
 

Good question, but the answer depends on the pair & timeframe...

Divergence occurring on an oscillator is a useful sign - pick from RSI, CCI, DPO, Momentum, OBV, etc

MACD works if the trend has been strong enough & long enough to make a reverse signal valid

Slow Stochastic will work to help define the limits of a (currently) range-based pair
