To narrow down AUDJPY you first right click on it from Market Watch, then click Specification and see what your margin percentage is. Divide that number by 50, if it is like mine. That is your number for column D.

Since you only want to trade 1% of your account, LOL, then first figure out if you have a margin call. Let's pretend you have one at 40%. So whatever your account balance is, you multiply it by 0.6 so you know your maximum risk. Then multiply that by 0.01 to get how much money you will use per trade. Then determine how large your stop will be and subtract it from that number. If you have any money remaining, that is how much you have to trade. Use that number as "B" in the above formulas. If they can calculate any lots at all, that is your risk size.

Example:
$10,000 with margin call at 40% means you have $6000 available for trading.
1% of that is $60 available to risk on a trade.
$60 is definitely a micro lot, and so if you have a stop of 50 pips, that is $5. Your money to risk is now $55.
With $55, I am not sure what your margin is at 1:500. I can only speak from what I know. For me, my leverage is 1:50 so I have a 4% margin.
You need to change 1000 to 10 since it is a JPY pair.
This means that for me, at 50 pips stop, 4% margin, each micro lot costs $39.13. With only $55 available for trading, I can only 1 micro lot.
So, you have $10,000 sitting in your account, with $6000 available for trading, but are only going to use $39.13 and make about 10 cents a pip.
Does that make serious sense to you?
Of course, you will need to adapt the math to your leverage, account size, margin percentage, margin call, and stop loss. Hope this gives you a starting point.
