Any divergence based on any indicator has to be confirmed FIRSTLY & FOREMOSTLY by price action.
If you spot a +ve divergence in a particular Timeframe chart, then go long when a pivot high (based on the same TF) breaks on upside.
Similiarly, in case of a -ve divergence, go short when the concerned pivot low is broken.
Divergence based on oscillators usually have their effect lasting till the said oscillator reaches its opposite side (eg., around 70 & 30, in case of RSI)
So, one can book part or most of the profits in this oscillator zone, and trail the rest.
Today, there was +ve divergence in RSI 1min chart, and it did its bit.
+ve divergence has also developed in 5min chart, but we still have to wait for the latest pivot high formed in 5min chart. Another supporting factor is the oversold status of 5min RSI.
Usually, good divergence effects are seen near known big supports & resistance levels - they can be known from this very thread by Nishikant.
