How does it work? How can we choose this shift? Wouldn't be pricing a different option with a different price wrong? Most importantly, what if the underlying price goes around the shifted barrier? You're right hedging digital binary options the "real" greeks of a digital option are unwieldy, hedging digital binary options, e.

So, what's the problem with this? In short, the price the trader quotes for the digital is going to be very noncompetitive, as the person asking for the digi could go and just purchase call spreads themselves though this is not possible for all underlyingsand so the trader will soon be out of a job. Using more leveragemeaning that they would model the digi call as a tighter call spread. Still no gap risk.

Using what you call a barrier shift. Here's where things can hedging digital binary options spicy. In short, this is changing where the call spread used to model the digi is centered. At this point, they're likely to still be uncompetitive without taking some unhedgeable gap risk via a barrier shift, but they would seek to keep their total digital exposure to a modest amount at any given time, hedging digital binary options.

First off, the delta of a digital is not "zero everywhere except at the barrier where it is an impulse", hedging digital binary options. Let's look at an example, just a vanilla call. One method to deal with this is to break up the option into several, with different strikes spread around the original one. Okay, so delta and gamma? So the delta has an extra step in the middle, and the gamma is still spikey, but now each spike is half the size of before.

Obviously we can do better still. Here's our new payoff, and the comparison to the original:. And again, delta and gamma:.

This is where risk limits come in. If you want to do one of these trades in small size, there is no need for this, since the maximum risk will be small. If you come to me and ask to do a mm digital though, then i could potentially have a very large hedge on my hands, so i will smooth the payout to reduce that risk - this is just another cost of doing a large trade.

If you can find someone else who is happier to accept enormous risk, then perhaps they will offer you a lower price. How much may differ, but as i mentioned already, this is also dependent on hedging digital binary options. And as you move to larger size, the market is going to shrink anyway, so you're going to expect costs to increase.

And for the barrier shift - why would the bank ever do this in any direction other than against the client? Why weight the notionals of the options evenly? Notice that the two methods are different - the first has a lower level for the whole region, but it appears abruptly.

Which you decide to go with will depend on how you want to manage things. Sign up to join this community. The best answers are voted up and rise to the top. Asked 3 years, 5 months ago.
