Notes on Combination Orders

This page contains notes and tips on creating and transmitting combination orders.

For example, an April 20.0 xyz call shows a BID price of 6.60 and an ASK price of 6.70. An April 30 xyz call shows a BID price of 0.15 and an ASK price of 0.20.

If you buy a "debit" call vertical spread with the following legs:
Buy 1 OPT APR02 20.0 CALL (6.70),
Sell 1 OPT APR02 30.0 CALL (0.15)
For this transaction you pay: 6.55 (a debit transaction)

If you invert the legs and buy a "credit" call vertical spread with the following legs:
Sell 1 OPT APR02 20.0 CALL (6.60)
Buy 1 OPT APR02 30.0 CALL (0.20)
For this transaction you receive 6.40 (a credit transaction, enter a negative price)
