about margin account

Can I ask some question about margin account?
If I have $100,000 cash in margin account,
How much is margin buying power?
2 times higher than cash money? so margin buying power is
$200,000?

 

$200K overnight/$400K Intraday (if you are a PDT)

 

If you have to ask, I highly suggest you do not trade with margin.

 

I am new to trade usa stock ,
What mean overnight?
what mean Intraday ?
overnight means I buy stock today and dont sell today?
Intraday means I buy stock today and sell all today?

 

Yes.

 

LeroyB3Ayes for me?
Thank you a lot!

 

If Intraday stock trading, must I pay margin interest?
or I must pay margin interest only for overnight?

 

answer?

 

You pay interest on margin only if you hold overnight.
There is no interest for use of margin intraday.
