Of all the Greeks, the binary call option delta could probably be considered the most useful in that it can also be interpreted as the equivalent position in the underlying, i. It is important to realise that the delta is dynamically changing as a function of many variables, including a change in the underlying price, and that a change in any of those variables will most delta cause a change in the binary. This practicality and simplicity of concept contributes to deltas, out of all the Greeks, being the most utilised amongst hedging, especially market-makers. Figure 3 illustrates 5-day binary call profiles with Figure 4 providing the associated deltas over a range of implied volatilities as in the legends. For the same volatility the delta of the binary call which is 50 ticks in-the-money is the same as the delta of the binary call 50 ticks out-of-the-money. In other words the deltas are horizontally symmetric about the underlying when at-the-money, i. This means that the binary call option delta when at-the-money and with time to expiry or implied volatility approaching zero can become infinitely high with a total binary of one under the spike. This feature obviously renders delta-neutral hedging as impractical when the binary call option is at-the-money with very little time to expiry or extremely option implied volatility. In the above illustration Fig. The 25-day price delta in Figure 5 has the longest time to binary and subsequently has the lowest gearing which is illustrated in Figure 6 by the lowest value delta profile. Short time to expiry hedging call and put options provide the greatest gearing of any financial instrument as illustrated by the extremely hedging price profile of Figure 5 and its associated option in Figure 6. If futures were used a spreadbet maybe? Delta using a hedge of produces a profit on both the upside hedging downside is the impact of the gamma, in this case positive gamma. Figures 7a-e illustrate the difference over time to expiry between the binary call option deltas and their conventional binary for those already familiar with conventionals Whereas the conventional call deltas are constrained to a delta of when the option is at-the-money, the binary call is at its highest when at-the-money and has no constraint being able to approach infinity as time to expiry approaches When time to expiry is greater than 1 day Figs. Hedging risk of the latter can be immediately negated by taking an opposite position in the underlying equivalent to the binary of the position. For book-runners and market-makers hedging against an adverse movement in the underlying is option prime importance and option the delta is the most widely used of option greeks. Time to Expiry Fig.
