2 days doesn't mean like it'll go out in 2 days
think of the LME as a supermarket
Stocks go in
Stocks go out
Sometimes outflows greater than inflows, so its a drawdown. Sometimes inflows greater than outflows so its an addition. At any one time there may be "2 days left" but there's always stockpiles coming in from an external sources(thousands of tonnes). Stocks can get replenished through new big mines and mine ramp ups/less stock drawdowns
