Question 1058584: Hello!
I would like to know the formula (and answer) for the following:
I trade currency on a daily basis (the market is open for 5 days per 7 day week), so if I began with $200, and I gained 10% on my principal on a DAILY basis, how long would it take me to reach $10,000?
For example, Monday = $200, Tuesday I would have $220 (200*10%=220), Wednesday I would have $242 (220*10%=242), etc. Is there a simple formula for determining how long it would take me to achieve a $10,000 goal, assuming I can make 10% gains every trading day using the previous days total as my new principal.
Thank you!
