[Directional]

Anyone know the specifics of the rules regarding under what circumstances IPE busts trades?

i'd heard that the IPE set some ridiculous rule busting trades if they occur more than 25 ticks from the last trade.

Cant understand how that could possibly work in a thinly quoted spread or back month outright which might not trade much, given how volatile brent is it would be nearly impossible for a trade to occur WITHIN that bust range!? the front month price sometimes hops 10-20 ticks in one go, never mind back months.
