Trading Is a Business, Not a Personality

Trading is often sold as a lifestyle because the lifestyle is easier to market than the arithmetic.

A trading business needs five things:

A defined market.
A repeatable setup.
A measurable edge.
A risk process.
Enough observations to distinguish skill from luck.

Without them, activity may still be interesting. It is not yet a business.

First, separate three behaviours.

Investing owns productive assets because their long-term cash flows and growth may reward patience.
Speculation accepts uncertain value and seeks profit from a future price.
Trading repeatedly applies a defined decision process over a stated horizon.

The same instrument can be used for all three. The label comes from the process, not the ticker.

Write the trading hypothesis:

In [market and session], when [observable condition], entering by [rule] and exiting by [rule] is expected to produce a positive result after spread, commission, slippage, financing and tax, because [economic or behavioural reason].

If “because” is missing, the setup is a pattern, not an edge.

Then define expectancy:

Expectancy = win rate × average win − loss rate × average loss − average costs.

A 40% win rate can be profitable when wins are much larger than losses. An 80% win rate can hide rare catastrophic losses. Accuracy is not the business.

Paper results are only the first filter. They do not reproduce execution, liquidity, platform problems or the emotional effect of money. Backtests can overfit: the more variations you try, the more likely one looks impressive by chance. Separate the data used to design the idea from the data used to evaluate it. Then use small live risk.

Leverage deserves suspicion. European regulators found that 74–89% of retail CFD accounts typically lost money in analyses underpinning product restrictions. The precise experience depends on provider and period, but the lesson is durable: leverage, costs and poor risk control can turn small forecasting errors into fast capital loss.

For a Swiss resident, provider and tax questions also matter. Verify whether relevant firms appear in FINMA’s authorised-institution lists and check its warning list. Understand where assets and cash are held, which legal entity contracts with you and what protection applies. Frequent, leveraged or derivative-heavy activity can also affect the tax assessment of whether you are managing private wealth or conducting professional securities trading. The facts matter; seek tax advice before scale.

Keep trading capital above the lower rungs and separate from the long-term portfolio. Do not trade the tenancy deposit, the tax reserve or money required to leave a job. A strategy cannot be evaluated honestly when life needs the next trade to win.

The first objective is not income. It is evidence.

The Field Note

Write one market, one setup, one hypothesis and one invalidation condition. Collect a clean sample before changing the rules. If you cannot state why the edge may exist and who is likely paying for it, do not fund it.

CHOOSE THE NEXT MOVE

01If the hypothesis cannot be stated or tested, keep the capital on W07.

02If it is testable, continue to W14 for position sizing, then W15 for the laboratory.
