why operators hold the game at stretched positions

- the longer the operators hold the price in the stretched zone, more the traders deepout of money lose by way of time decay.

- the profit to operators by going towards profitable zone has to be substantially more than the effort of making the necessary moves.

- they want time for distribution.

- the amount of premium operators stand to gain by time dacay by not allowing bank nifty to slip is 2 times their potential loss by letting it slip. as the expiry approaches operators get torn between which profit to take. the one by swinging the price or the one by letting premium decay.
