Example of an account balance:
You signed up and deposited $1000 via credit card
1.00pm - You buy 300 Silver Ounces at a market price of $20.00 with a Take Profit call when Silver reaches $25.00.
The total amount you bought is: 300*$20.00 = $5,000
The Margin needed for Silver is 10%: $500
If your equity falls below $250 you will get a Margin Call.
2:00pm - Silver jumps to $23.
2:15pm – Silver jumps to $25 - Take Profit executes
