I cannot offer any explanation. All I can tell you is that Intellichart and Comstock, which feed FXCM customers hit 1.3200 twice Sunday night. It's right on the chart as plain as day.
Brokers like FXCM do all they can to not pay out. 1.3200 would have been a huge take-profit number and thousands and thousands of longs would have cashed out at that point. Their games on Sunday kept that from happening.
