Position management.
Normally do not hold until expiry. Take profit when it is reasonable amount (e.g. 100%) or to consider cut loss when it skew towards $31 or below.
Also consider to close positions if price of Middle Leg drops to $0.25 or lower OR if its time premium left drops to $0.125.
At expiry, if QQQQ is above $35, no action needed and all PUTs expire worhtless and we will lose max amount $490. But if it is below $35, some of the PUTs (31, 33 and 35) will get exercised. Which is the reason why we prefer to close out the positions before expiry.Summary : we are expecting QQQQ to stay within the range of $31 to $35 from now until 19-Jun and volatility to reduce or stay flat. (QQQQ is NASDAQ-100 ETF).
