How Much Capital Do I
Need?
     

 

How Much Is
Enough?
You can have the best
system in the world, being traded by the best trader, and still
go broke. This often happens by not having enough start
up money. So how much do you need? The short answer
is, "It Depends". It goes much more in depth than that
though.
Most traders are way
underfunded. I often see people trying to trade a system
with a 3000 pip drawdown with a $3000 account. While in
theory it looks like you should survive and thrive in this
situation, past experience has shown me otherwise. In a
similar situation lets say that you're trying to trade a system
with a max drawdown of 900 pips with a $1000 account. If
you were to hit that 900 pip drawdown right off the bat you
would have a 90% drawdown. To get back to even you would
need to go on a 1000% rally. This is not at all
likely.
Factors to
consider:
-
What is the traders max
drawdown?
-
How much margin is tied up in open
trades?
-
How much history do you have on the
trader?
A traders max
drawdown can be deceiving. You need to realize that this
is the max draw down that has happened "so far". If you
don't have a lot of history on a particular trader you probably
shouldn't be using their signals in the first place, but you
definitely shouldn't trust their max draw down.
You also need to
factor in margin requirements. This is money that is not
available for you to draw down. You WILL get margin
called, and all of your trades will be closed, if you
don't take this into consideration.
So How Much Is
Enough?
To be safe, you should
choose a trader with enough history to have a reliable
drawdown. Then once you figure how many trades they
generally have open at a time, you can determine your margin
requirements. My account never has less than twice the
max drawdown of a trader plus whatever margin requirements may
be. I also use this formula when adding new signal
providers. This allows me to know that I am not at risk
of a margin call as long as I monitor my accounts
daily.
I also add up the
maximum ammount all of their trades draw down and then divide
it by the number of trades. This will give you the
average ammount of pips that their trades run against
them. This number is never more than 5% of my account
balance. To be conservative you should probably try to
keep it under 3%. This may seem quite conservative, but
it allows you to survive and trade another day.
If you do choose to
trade with an underfunded account because you want to "take a
shot", that is fine as long as you know that that is exactly
what you are doing. You may go on a run at the beginning
and never look back. But if you continue to increase your
lot sizes as your account grows, and always trade an under
funded account, you will eventually go broke no matter how good
of a trader you are.
