**How to use Greeks.Live Auto DDH service? **(2023–01–18 update)

# Enter www.greeks.live/tools

Click the “Language” menu on the upper right corner to choose English.

On the upper left side of the Auto DDH page, you can see the “List of Accounts”, where you may choose the main/sub account through which you wish to use the Auto DDH service.

# Set Parameters

Two items need to be set on the parameters page.

**Delta Target**

“Delta Target” refers to the value “Delta Total” will be adjusted to after each hedge.

“Delta Total” is the collective Delta exposure of all your options and perpetual/futures positions.

The default value of “Delta Target” is Zero. So, after each hedge, you will have a Delta Neutral portfolio.

Nevertheless, if a trader deems the market to be a bull market and wishes to have positive Delta exposure after each hedge, he can set “Delta Target” to be a positive number. For example, if he sets “Delta Target” to be 5, then after each hedge, the portfolio’s “Delta Total” would be +5.

If the trader wishes to have a negative Delta exposure after each hedge, he can set “Delta Target” to be a negative number. For example, if he sets “Delta Target” to be -3, then after each hedge, the portfolio’s “Delta Total” would be “-3”.

# Delta Threshold

“Delta Threshold” is the limit of the absolute value deviation of the portfolio’s “Delta Total” against the “Delta Target” set by the user. Beyond this limit, a Delta Hedge will be triggered.

For example, suppose that your “Delta Target” is “0”, and your “Delta Total” is “-0.2” or “0.2”, the absolute value of deviation will be “0.2”.

If your “Delta Target’ is “1”, and your “Delta Total” is “0.8” or “1.2”, then the absolute value of deviation will be “0.2”, too.

In my example shown in Picture 7, the “Delta Threshold” is set as “0.1”, and the deviations in the above two examples are both beyond “0.1”. In these cases, a delta hedge will be triggered to bring “Delta Total” to the respective “Delta Target”.

Our program will check the deviation every 10 seconds.
