I know that in futures, we should have our money in the brokerage account as said in initial margin requirements for buying particular futures contract.....Then there will be specifications for the contract like contract size, tick size....Based on the Contract size and our betting will move.....If our bet was wrong then we will be losing money and once it reached the maintenance marigin , we get the marigin call to add funds to rebound to initial marigin......This is how futures work ...correct?

1.Now, what is the dfference between currency futures and trading currency ?Does trading currency ordinarily involves same like initial marigin amount, contract size and maintenance marigin?

2.Now, does hedging in future contract does not have marigin requirements?Like Buy USD/AUD & Sell USD/AUD in two different trades?If yes, does hedging in all futures ( currency, index,interest ratesetc...) dont have marigin requirements?


Thank you .
