Obviously, mathematically one does not. You could easily drop a zero and raise the DD to -3% which would be more than acceptable.
Show me better. I was just browsing FundSeeder, started by one of the most regarded traders and my trading blows away their top 3 forex traders stats.
If he added a zero to his size his margin used would be 2.2 million, and he's got only 1 million in the account.
No, you asked if one needed 1MM. My response was drop a zero off 1,000,000 to make it 100,000. That would increase leverage from x1 (zero leverage) to x10 leverage, that would then increase DD by 10 to 3% as an example. Pretty straight forwards, I will assume you are just playing around wasting our time, which is fine.
Now the opposite of same question asked earlier. Sure, add a zero to make it 10MM and that would increase DD by x10 to 3% as an example. Not sure why you came up with 2.2 margin, but it would not really matter. Either way it would be x10 leverage, hence the x10 increase in DD.
