Hello, I've never traded forex before so I have a very basic question I hope someone can answer for me. Let's say I put $100k USD into a forex account. Then I decide I want to go long 100k CAD/AUD. How much of my USD will be converted into CAD to execute this trade? If too much of the USD is converted then I could make on the CAD/AUD trade but then when I reconvert back to my base currency (USD) I can end up losing net. Leverage is most likely the answer but I'm not sure of the details. Will my system automatically convert at 100/1 leverage even if my position is so small that I could trade at 1/1 leverage? Any insight is appreciated. Thanks.
