GBP/USD: Intrady Key Levels

As we can see on the M15 chart, the price gets close to reaching the demand below.
This demand seems like a fresh one and a great level for intraday buy position.
I'll buy at this demand and the target for this position will be the supply at the top.
This supply is also a great level for sell position, we can see how fast and strong the price dropped from that level.
I'll sell at this supply if the price reaches there.
