Nocks determine calculated prices based on supply and demand on the markets in question. The healthier and the more volume a market has, the better prices Nocks can offer. If the order books of Gulden (NLG) are out of balance for example, that means there will be a bigger gap between buying and selling prices. This is called the spread in trading terms.
The Gulden apps, that use Nocks services, are giving an estimate of how much it thinks the Gulden are worth in euros, 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;
- It is constantly changing;
- 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;
- Your phone battery will drain very quickly if it were to constantly get the information in real-time, causing a slightly outdated rate at times;
- The amount of Gulden involved changes the rate per NLG and the app cannot calculate this.
When you purchase from Nocks they will use an exact rate calculated for your exact transaction, these figures should roughly line up with the rates displayed in the Gulden apps but there are always going to be some anomalies.
