Going Full Time: The Arithmetic Before You Quit

Career and Funded Trading

The decision to trade full time is usually framed as a question about skill. It is mostly a question about capital and cash flow, and the arithmetic is unforgiving enough that it is worth doing on paper before it is done with your life.

Start from the withdrawal, not the return

Decide what you need to take out of the account each month in living costs. Then work backwards. A trader withdrawing 2 per cent monthly needs to earn well above 2 per cent monthly to grow at all, because withdrawals come out of the same capital that produces returns and they do not stop during drawdowns.

And 2 per cent per month, net, consistently, is a very good professional result — not a starting point. Most traders who make this move successfully do so with the lower withdrawal rate, which doubles the capital requirement.

The three buffers

01

Living buffer

Twelve months of expenses held outside the trading account, in cash, untouchable.

02

Drawdown buffer

Capital above the minimum, so a normal 12 per cent drawdown does not force a change of lifestyle.

03

Income buffer

Part-time or contract work for the first year. Removing the pressure to earn this month is worth more than any indicator.

What changes when it becomes the income

Everything about the psychology inverts. A losing week stops being a statistical event and becomes a rent problem. Traders who were disciplined with a salary behind them frequently fall apart without one, and the failure mode is predictable: increased size after losses, trading outside the window, taking marginal setups because no setup means no income.

Test first. Spend six months withdrawing your full living cost from the account while still employed. If the account survives that and you survive the feeling of it, the transition is a formality. If it does not, you have learned it cheaply.

Run it as a business

  1. Separate accounts: trading capital, business expenses, personal money. Never mix them.
  2. Pay yourself a fixed monthly amount rather than a share of profit. It smooths behaviour as well as cash flow.
  3. Budget for tax from the first profitable month, in the jurisdiction where you actually live.
  4. Review the decision annually with the same detachment you apply to a strategy.

Trading full time is not a promotion you earn by being good. It is a business you can afford to start.
