First off, if relevant info is listed per exchange and reg authority site(s) just post links and I'll go digging 
Let's say neither a broker nor its customers have pre-existing positions in a market e.g. WTI Crude. I buy one futures contract which the broker sells to me via in/outside clearing body to the exchange. They are now short WTI Crude...how much time are they legally allowed before hedging their own short exposure? 1 minute; 1 day; 1 week?
Far as 'style' of hedge, is it mandated to be an exact method or can they get creative? For example, I'd assume that any regulatory body, in this case the CFTC, is not going to state "make sure yer delta-neutral, bud" in their regs, so the broker could be doing a simple leg-into a Cal/Fly spread, or perhaps going into the options markets for some gamma/volga/vega-neutral far I/OTM acrobatics.
Anybody have knowledge, preferably 1st or 2nd hand, of what goes down for this part of the broker's daily ops?
