Just tried to make it very simple as possible. Wasn't really looking at GBPUSD like that this week, but I decided to see if there was an opportunity in the market.
This looks like a nice risk to reward factor for gbpusd.
I looked for an impulse move to the down side because the trend is in a downtrend.
Marking the last bull candle. the target was the last bear candle to the impulse move to the upside.
This OB method is just supply and demand.
