The aim here is to do your long entry when the Starc bands are in a good position.
What is a good position?
Well, if the Starc bands were right close to the upper Bollinger band, then you know that you do not have much more āupā to go.
So in that case you would not enter long but, rather, wait.
Now if the Starc bands were near or closer to the lower Bollinger band, then a long entry would be a good idea.
The Starc has some distance to travel up and you will then profit from the rise.
If the Starc bands were to fall suddenly, they would not fall far before reaching the lower Bollinger bands and changing direction to go up again.
[B]You can see now why the Bollinger bands are so important on the 5 minute Starc band chart.[/B]
So to place a long, we do so closer to the lower BB than the upper BB.
That way, the probabilities are in our favour, that the Starc bands, and hence the price action, will go up rather than down.
