ETP rebalancing flow क्या है?

The ETP rebalancing flow is the quantity of futures that leveraged and inverse volatility products must trade at the close to restore their multiples, $A\,L(L - 1)\,r$ for each product; it is zero for $L = 1$ and has the sign of the day’s move for $L = -1$ and $L = 2$, so these products buy after rises and sell after falls.
