The post crash low  at 1.2087 area is the next target ahead of open road (to the downside)
The GBPUSD has ripped through support targets like a hot knife through butter. The 60 pip range seen at the start of the NY session,  is now about 150 pips.  The next target is the post-GBP crash low at 1.20876  and then a lower channel trend line at the 1.2082 level.  A break below those levels puts trading in more open road to the downside.
