Something odd in BP & Euro COT

Figures published Jan 21st show a massive fall in Commercial longs and rise in Commercial shorts in both Pounds and Euros. Contrariwise, Big Specs show large rise in longs and large fall in shorts. Nett figs have switched over - BP Commercials are now nett short (from nett long), Big and Small Specs are nett long from nett short - Euro Commercials are now nett short from nett long, and both Big and Small Specs are nett long from nett short. Thought is needed - conclusions asap ....
