Running back of the ZN1! Waiting for pullback or break

The market was going down for a while now, with few pullbacks on the supporting blue line.
When volumes increased we noticed a strong break of the support. A powerful move not giving anymore room for a short entry.
Market gave us a signal of return to the support line which is now a resistance line.
Line that have seen some past pullbacks, therefore, we look at possibility of pullback or a break of that line for a change of market trend.
