how to calculate corelation between FX and barrier options prices

Recommended Posts

We know that barrier option move/reflect like fx prices.
Let say we enter EURUSD market in barrier option when fx price is 1.1200
then we want to place a stop in barrier option that would be equivalent as having a stop in fx of lest say 50 pips.
how do we calculate the barrier option price for that stop?

Thank you.

The Barrier price is the distance between IG’s underlying price and the knock out level + premium. For example as below, the market is 28725 and the KO is 27000 (which is a difference of 1275). The KO premium is 10, so the price is 1285.

In your example the barrier price is the 50 points plus whatever the KO premium is. 

If you fill in a deal ticket, the premium and price should auto populate.

    • Thank you JamesIG for your explanation of how IG determine their price charts. "This means there will always be a discrepancy with the highly publicized index price" ... Yes that is also noted but your company "interpretation" has the low 9 days before the other outlets. However you want to spin (explain) it. That makes it incredibly difficult to ascertain what a real low is.....is it the one you show or the one the others show? It also, at least to me, appears that best practise would be served if the resulting price chart reflects the index it purports to follow/promote. EWT users ( I follow a US analyst) will know the frustration. His DOW chart shows a different low....and therefore a different count. Tongue in cheek.....so when was the recent low in the past two weeks?
