Immediately after you buy a license, you will receive by email a code.
Provided that you have already installed Deriscope, when you start Excel and click on the Deriscope ribbon item, you will be asked by the Deriscope wizard to enter that code.
This part requires no interent connection and creates a local cdm file in your computer.
You will be able to see the location of that file through the wizard.
As long as that file stays in that location, you will be able to use Deriscope according to your license terms, without any dependence on outside servers - except of the live feeds part - since all required Deriscope dlls are locally stored in your pc.close

Live Feeds refers to the acquisition of real time market data and historical time series from various providers as explained here.

Cash Flows refers to the computation of projected future cash flows, such as bond coupons, swap payments etc.
In case these flows rely on certain curves, then they will be computable only if your license also supports the creation of these curves.

Showcase example: Swap.close

Bond Maths refers to the computation of bond metrics such as clean price, duration, convexity etc.
In case these metrics rely on certain curves, then they will be computable only if your license also supports the creation of these curves.

Showcase example: Bond in Excel.

Pricing refers to the calculation of the fair value - also known as NPV (Net Present Value) - of all asset types listed under COVERAGE.

Showcase examples: FX Forwads & Swaps, Currency Swaps, Stock Option, American Option, Asian Option, Swaption, CDS.
Technical details here.

VaR refers to the Value at Risk computation of a single asset or a portfolio of assets.
All licence types, except the Professional, carry the constraint that the number of simulated scenarios does not exceed 1,000 and the number of assets in any given portfolio does not exceed 5.
The VaR of a certain tradable can be only computed if your license supports the pricing of that tradable.
Technical details here.close

Flat Curves generally refers to curves created with a single number as the market input.
The typical example is a yield curve that represents a constant (flat) continuous compounded interest rate.
Exceptionally curves that cannot be created as flat - such as discrete dividend and inflation curves - are also supported.
Note that flat curves represent a good approximation in several real life situations.
As a matter of fact, they carry on approximation cost in the case of single terminal cash flows, such as European Options or Zero Bonds.close

1-dim Curves refers to a curve construction out of one-dimensional market data.
An example is a yield curve built out of an array of swap rates.
Another example is a volatility curve built out of an array of maturity-dependent vols.

Showcase examples: Domestic Yield Curve --- Foreign Yield Curve.
Technical details on all curves at the bottom of COVERAGE.close

Multi-dim Curves refers to a curve construction out of two-dimensional (or higher) market data.
An example is a volatility curve built out of a table of vols that depend on both maturity and strike.

Showcase example: Swaption Volatility Cube.
Technical details on volatility curve types here.close

Non-Flat Risk refers to the generation of an array (or arrays) of NPV changes, where each array element holds the NPV change caused by a shift in a specific input market rate.
For example, the NPV may depend on a yield curve built out of 1 deposit, 5 futures and 10 swap rates.
Then the non-flat risk wrt this yield curve would appear as three arrays, totalling 16 elements.close
