Hello, I am euro based and I am currently intraday trading Micro E-mini S&P futures. Could someone give an advise on where to find an example of hedging currency exchange rate risk when opening positions of index futures contracts?

Do you really have currency risk by opening a 'position'?

You obviously have currency risk depositing money into a brokerage account with a difference currency to yours, and any money you make has currency risk, but I'm not sure just opening a position has risk?

You are obviously right and I did not describe it properly. The currency risk is obviously on the capital and I it is my first time I want to hedge for exchange rate fluctuations. Obviously I am new in trading and my problem is, I have for example 10000$ capital and I have to hedge against Euro/Usd fluctuations. How do I calculate how many Euro/Usd FX contracts I need to sell or buy for this capital to be hedged? Is there an example somewhere, which is a bit easy to understand and study it?

The smallest future is the Micro EUR/USD M6E which is EUR 12,500 so about USD 14,500. If you literally have $10,000 that would mean your choice is to either be completely unhedged or 45% over hedged! Sorry.

Since your natural currency is EUR and you have bought USD, you need to sell USD to hedge the position, hence would need to buy a Micro Future.

Another way to think about.
You exchange your EUR 10000 into USD at 1.15 and have USD 11,500
If EUR/USD goes down to 1.1 your USD will now buy you back EUR 10,454 which is a profit.
If EUR/USD goes up to 1.2 your USD will now only buy you back EUR 9,583.
Hence you need to protect yourself from rates rising and would need to buy a futures contract.

Thank you SMCJB very much your reply.

You were very clear and I have understood the way to do it. Ninjatrader which I use, calculates the balance from Euro to Usd in a daily basis, which basically my account in dollars is smaller every time euro losses value against usd. Hence, i guess I need to do the opposite and sell usd in order to hedge my account?
