What should you watch out for? (When doing a hedge)

The following things:

Net exposure

If you want to hedge several positions, it is advisable that you first calculate the net exposure. This results from a comparison of liabilities and claims (sorted by currencies and due dates).
The balance (the net exposure) is used for hedging. Otherwise, you would hedge each position individually which is very complicated.

Risk evaluation

Value at risk methods are used to evaluate the effects of price changes. Value at Risk on the one hand means giving up profit potential but on the other hand, also means that you protect yourself against losses.
It is also important to keep an eye on the liquidity of futures. A future with a higher trading volume is generally preferable.
