To calculate the maximum loss possible before getting a margin call:
Determine the amount of initial margin requirement (IMR) and maintenance margin requirement (MMR) based on the futures contract specification and the number of contracts you will acquire. Be sure your initial deposit (ID) is larger than your IMR.
Subtract MMR from ID. Now, you have how much you can lose.
Divide the loss you can bear by contract points value, and you will get how many contract points you could withstand.
