the question should not be how much you can short, the question should be
how much you can profit from doing so. |
G*******m
发帖数: 16326 | 3 you need at lease $20,000 in your account to short options.
if you have enough fund in your account ready to buy assigned underline
stocks, then you can short that amount of options.
for examples, cash account has 30,000, shorted SPY 109 put at 4, then the
cost is 105, maximum you can short is 30,000/10500=2.85, so it is 2 options
you can short. |
G*******m
发帖数: 16326 | 4 if the above is a margin account, you can short 8 options. |
G*******m
发帖数: 16326 | 5 naked short call options needs a lot more, $100,000 minimum after the margin
meeting related requirement. |

G*******m
发帖数: 16326 | 20 because put options more expensive in a down day and more often than not
that stock/index will down more later in a down day and may continue to down
next day

different brokers have different margins.
it is about how good that you are at trading instead of anything else.

发帖数: 16326 | 24 sell at the money options is better. |
G*******m
发帖数: 16326 | 25 For example,
Sell at the money, got $3.6, then price goes against you by $2.00
Close the deal, and sell at the money again for $3.6
The first trade lost $1.2 (not full $2.0 because of the delta difference)
If the 2nd trade goes well, there will be still $2.4 profit (3.6-1.2) |
G*******m
发帖数: 16326 | 26 Another example,
Sell at the money, got $3.6, then price goes against you by $20.00
And you have trouble log into your account because of heavy traffic.
Then what? |

You always have to bet on one side, there is never a "never" rule. You
never know if the market will go lower the next day, no one has a crystal
ball. |
