I am trying to see what is the tick in IB for future option, managed to figure it out.
Use Coach recent diagonal put as an example of selling the SEP EW 1340 and bought the OCT ES 1360..
The tick in IB is ES. last night with ES Sep Future ESU6 at $1305.25
ES Sep 1340 Call Future Option EWU6 $4.80b $5.50a (select EW class)
ES Oct 1360 Call Future Option ESV6 $4.15b $4.50a (select ES class)
The commission should be $1.65/contract in IB for option future.
Anyone could advise me what much is the margin required in IB ?
Future options use SPAN margin. Without software, there is no easy way to calculate the margin requirement as it takes into account your complete position on each underlying. What's more, the margin required changes constantly depending on time to expiration, volatility and movement of the underlying.
For a single put diagonal, with no other positions, the maintenance margin increases as time passes and as the underlying moves towards your short and decreases as volatility increases.
On IB, you can select the order and right click on "check margin". This will show you what your margin requirement will be (including existing positions) if your order is executed. You want to have at least twice as much available as this doubles overnight plus a good reserve to be able to keep the position as market conditions change.
