Here are some current things I am looking at.
To better explain my buy zone, anytime significant support/resistance areas are broken. That area becomes my Buy Zone/Reaccumulate area.
To keep from buying too early, despite knowing multiple retests will come, like it always happens. I restrict placing any additional orders unless it enters:
Above
Within
Below
My zone.
If you want a neat trick on when to take PARTIAL profits on the way up. You right click on your drawing and hit clone. It will automatically place a copy of your line/box on a significant price area. If price action is still continuing upwards, simply re-clone the new one.
Trust me, I don't question it. I just take advantage of it.
If you are having trouble getting your cloned Lines/zones from being placed higher/lower, depending on your risk tolerance, flatten/raise the chart layout. Won't take too many tries till your satisfied.
