I will now go thro a live trade with an evening star pattern step by step using the BB-KC-MACD approach to get the very best entry.
Firstly study the chart below. Notes below the chart >>>

The chart shows a beautiful evening star highlighted in light blue. The 2nd candle has peaked beautifully.
It is also on the upper Bolinger band which, together with the lower band, is shown in grey. The middle band is in blue.
The profit potential is shown by the dark blue dots - you
trade short as far as you dare or use a MACD or stochastic or otherwise.
Now the 4th candle (green) is the entry candle at 11.45am. You can see that this candle has a very long upper shadow (wick).
The traditional
shorting entry point is at the bottom of the 3rd candle and I have labelled this point "
poor entry"
If you were to enter near the top of the wick you would have the "great entry" as labelled.
The difference between the
great entry and the
poor entry is about 30 pips.
This is a whole shorting trade in itself let alone any further pips we get from shorting from the traditional entry point !!!
So you can see that good entries here can make a difference. This is for scalping. If you are a position trader (long term) then specific entry points would make little difference.
When you are looking to trade this set up it is assumed that you have a 5 minute chart fully ready with MACD, BB and KC already on it. You are already watching it, and when the 4th candle appears on the main chart, you are ready to attack.
Next chart - the 5 minute for best entry.
