Nocks determines calculated prices based on the supply and demand principle as performed on the open Gulden trade market. The balance of supply and demand is determined by buyers, sellers and day traders of all sizes. We use trade data from the Nocks Trade platform to determine value.
Spread determines the difference
If the order books of Gulden are out of balance, meaning a larger gap, or spread, between BIDS (what the market wants to pay for the currency) and the ASKS (what the market's asking price is for the currency), that means there will be a bigger spread between buying and selling. Which means that when you want to sell or spend your Gulden, the bids determine how much Gulden you need to complete the transaction.
This causes a fluctuation in value from point of purchase to point of selling.

Pricing on websites and in-apps
The Gulden apps (gulden.com) and other third-party statistic websites are giving an estimate of how much it estimates the Gulden are worth in a certain currency, to try be helpful - because it is more useful than just seeing the Gulden amount, it is not and cannot ever be an exact number because;
(1) It is constantly changing;
(2) There are at least 10 different ways, if not more, to measure how much your Gulden are worth – all of which are wrong in various situations;
(3) Your phone battery will drain very quickly if the Gulden app were to constantly get the information in real-time, causing a slightly outdated rate at times;
(4) The amount of Gulden involved changes the rate you can get or have to pay per NLG and the app cannot calculate this.
When you purchase from Nocks or make a money transfer to IBAN from the Gulden app or via the Nocks platform. Nocks will use an exact rate, based on the real-time Gulden exchange market, calculated for your exact transaction.
These figures should roughly line up with the rates displayed in the Gulden apps or other third-party services but there are always going to be some anomalies.
