I have been doing a bit of calculations to see what I come up with and wanted to share the following with you. Hopefully you can use it and help me understand if I am totally wrong. I was trying to figure out how to get 1% - 2% a day, but so far I am not coming close.

Assumptions:
Short GBP/USD and Long USD/CHF in ratio of 1:2. Current YTD Correlation between GBP/USD and USD/CHF closing prices is -0.63. That is how I came up with the ratio of 1:2

Based on published swap rates at IBFX on mini accounts, you would earn an overnight swap of $1.81 for each set of 0.3 lots you hold (0.03+0.89+0.89)

Take a $5000 account and trade 50% of your capital (50:1 leverage) you can hold 1.25 lots. Very high leverage and not really what anyone advises, but this is for illustration purposes.

So what you have now is 4 sets of 0.3 lots (1.2 lots) and $1.81*4 =$7.24 swap per day. This represents 0.14% interest per day.

If you fully invested your 5k account at 100:1 leverage and NEVER got a margin call, you could theoretically hold 5 lots. This would pay you a daily swap of $30 (remember 1:2 leverage earns $1.81 for every 0.3 lots). $30/$5000 = .6% daily interest.

I know I must be missing something in the strategy as maths is not my strength, but based on the daily swap I cannot see how to get 1% of the account.
