Here is one example that shows the advantage of using different Time Frames to help us decide when to enter.
In the picture you can see:

All 3 charts when NY opened this morning show us as follows:
200 EMA were blue (uptrend)
Super Trend histogram were blue
Heiken Ashi candles were blue
Hidden diversion on 15 mins chart
Classic diversion on 5 min charts

So everything was pointing for a buy.

To exit the trade and cash it:
1. When price touched the Monthly pivot
2. When we had divergence against us on 15 and 5 mins TF
3. When EMA turned red on 5 min charts
