i What this calculator does
A psychology risk calculator evaluates your current emotional and cognitive state using research-backed indicators that predict impaired trading decision-making. Based on your responses, it gives a session readiness score and recommends whether to trade at normal size, reduced size, or not at all. It quantifies the most common but least discussed risk factor in retail trading: the state of the trader.

Frequently Asked Questions
Is trading psychology actually measurable?
Partially. Research in behavioural finance identifies specific states - sleep deprivation, financial pressure, emotional elevation, loss-recovery motivation - that reliably predict impaired decision-making. This calculator quantifies those known factors.
Why does sleep quality matter for trading?
Sleep deprivation increases impulsivity, reduces risk assessment accuracy, and impairs the ability to follow rules consistently. Even modest sleep reduction measurably affects financial decision-making quality.
What is loss-recovery motivation and why is it dangerous?
It is the state of entering a session with the goal of recovering a previous loss. Research shows this motivation leads to larger position sizes, reduced patience for setups, and more rule violations - the exact conditions that produce larger losses.
Should I always skip trading when the score is below 40%?
Yes. The session's expected cost - from larger impulsive positions and rule violations - statistically exceeds any expected profit. The correct professional response is to observe without trading.
Can I use this calculator before every session?
Yes, and you should. The value comes from consistency. Over time, comparing your session scores with outcomes reveals your specific performance-psychology relationship.
How do financial pressures on SA traders differ from other markets?
South African traders face specific pressures: load shedding creating connectivity anxiety, ZAR depreciation eroding account values in real terms, and access to SARB allowances creating urgency around offshore funding. These are local versions of general financial pressure.
Does this replace professional psychological support?
No. For persistent emotional trading issues, a registered clinical psychologist or financial therapist with trading experience offers professional assessment and intervention that this tool cannot replace.
How is a 'psychological risk threshold' actually determined?
It's inherently personal, reflecting the position size at which your own emotional response starts measurably affecting your decision-making, often identified through honest self-reflection on past trades or gradual, deliberate testing at increasing sizes.
Can my psychological risk threshold change over time?
Yes, with experience, consistent results, and genuine confidence built through track record, many traders find their threshold gradually shifts, though this should develop naturally through evidence, not be forced prematurely.
Should I always trade below my psychological threshold?
Generally yes, trading meaningfully above the size where emotion starts interfering with your decisions tends to produce worse outcomes than your strategy's underlying statistics would otherwise predict.
How do I know if a bad decision was caused by psychology or poor strategy?
Review whether the decision violated your own predetermined trading rules and plan, a strategy problem shows up as a flaw in the plan itself, a psychology problem shows up as deviation from a plan that was otherwise sound.
Does this threshold apply the same way to both wins and losses?
Not necessarily, some traders find losses trigger emotional decision-making at a lower threshold than wins do (or vice versa), worth honestly considering both directions rather than assuming symmetry.
