I'm going to set a reminder for this unbelievable and weird post of yours in 15 days, and when that time comes, I'll check back to see if you achieved your goal of using $7 to earn $2,293.76 or not. This is the fifth day(9th) of the 15-day period, which should fall around the 19th of this month. I believe by now, you are making these gains as you have planned it to work out for you.
The plan: 15 days starting with 7$
Calculation: 7x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2=229376
15 days in one month there will be big swings enough to give me at least 100% ROE.
