That depends on;
- How much you need to cover your cost of living.
- what your average monthly performance is
Then you need to make allowances for those months where you wont be making anything.
It will vary from person to person and their own individual performance.
lets say you need $3000 per month to maintain your current standard of living. Or, you currently earn $3000 per month.
Then, lets say, you perform at a 3 month average rate of return of 5% per month. Also, you dont want to reduce your current standard of living.
You would need, at least $60,000 in your trading account.
Now, lets say that you will call it quits at a 50% draw down. This is the point that you will return back to full time employment. Since the potential recovery would take too many months of trading. You would still need to make withdrawals to cover your cost of living.
This means that the minimum viable amount required to trade for a living is $30,000. Pus some change to see you through while you get your next pay check.
That is, with those variables and conditions.
