Hi again @Zhadow45,
In the image below, we have highlighted the section of the Account Manager on TradingView where you can monitor your margin.
In the example above, the demo account balance is about $50,000 and we have an open position with a notional value of 100K. That means our effective leverage is about 2 to 1, since 100K is 2 times 50K.
If you opened a position with a notional value of 1 million, with the same demo account balance, then your effective leverage would be about 20 to 1, since 1M is 20 times 50K. US forex trading regulations allow up to 50:1 leverage on major currency pairs.
We discussed effective leverage in more detail in this post: Capitalizing Accounts
