I think the idea is after year 1 you have doubled your original 25K ..
So in the 2nd year your own stake is now 50K x the 5x leverage so that means an account size of 250K trade not 216K
After year 3 your own stake would have grown to 100K and the with leverage you are now trading a 500K account......not 259,200 and so on......basically you are doubling your original stake year on year with the 5x leverage if you can achieve the 20% return per year...
I am only new to CFDs myself and only use 10% of my total portfolio for this type of trading and no more then 3 or 4 positions at any one time.
As has also been mentioned the risk needs to be under 2% per trade otherwise I will reduce the position size..
Thanks makes sense now , end up with 3.2m after 7 years. Just a bit misleading whereever you read it to state 15to20% instead of the actual 100% return on investment invested, makimg it sound easier than it actually is.
