Quote from spindr0:
Long options have no loan value so when bought so they must be paid for in full (100% of their cost).
Sure they must be paid in full, but IMO, as I understand them,
Ameritrade asks for an additional ("safety") margin.
I'm curious as to what you meant by "TDAmeritrade asks for 100% margin for buying a Long Call or Put option!"
Is this some blurb you read at their web site or are you saying that they require that you must have the cash to buy/sell the stock?
I just don't understand what they mean with "margin". My understanding
of margin is that usually when shorting stocks or options a margin safety
must be present in your account. But buying a Long Call or Put has nothing
to do with Short Selling or Short Buying, therefore it is confusing why they mention "margin" for Buying Long Calls or Puts at all.
This is from TDAmeritrade's "Margin Handbook" (page 12).
How do you understand what they mean with "margin".

Long straddles
Margin requirements for purchasing long straddles are the same as for
buying any other long options contracts: 100% of the purchase price
for each side of the straddle.
Example of a long straddle:
Action: Buy five puts STUE Corp.
Date: March
Price/Share: $39.25
Market Strike Price: $40
Option Premium: $2.50
Action: Buy five calls STUE Corp.
Date: March
Price/Share: $39.25
Market Strike Price: $40
Option Premium: $1.75
Since this is a long straddle, the margin requirements are 100% on each position.
Long Put Requirement
$2.50 x (5 x 100) = $1,250
Long Call Requirement
$1.75 x (5 x 100) = $875
Requirement $2,125
