Trading Psychology Glossary

The behavioural patterns behind ~75% of trader churn, defined.

Tilt

A neurological state where the brain's stress response suppresses disciplined decision-making, causing a trader to abandon their strategy and execute impulsive trades within minutes of a losing event.

Tilt is a neurological state where the brain's threat-detection system overrides disciplined decision-making, causing a trader to abandon their strategy and execute impulsive trades. The term comes from poker, where a bad beat sends a player "off their game." In trading the behaviour looks identical: rapid entries, ignored stop-losses, position sizes that exceed every rule the trader set that morning. The underlying mechanism is not weakness or a discipline failure. It is an amygdala hijack, and it has a measurable chemical signature that any trade-event monitoring system can detect in real time.

Revenge Trading

Re-entering a position within sixty seconds of a closed loss at a larger position size, driven by the neurological urgency to recover the loss immediately rather than execute the planned strategy.

Revenge trading is the act of re-entering a position within seconds of a closed loss, at a position size larger than the original trade, driven by the emotional need to recover the loss immediately. The signature pattern is identical across retail brokers, prop firms, and crypto exchanges: a closed losing trade, a re-entry within sixty seconds, and a size that deviates upward from the trader's recent baseline. The trader has stopped executing a strategy. They are responding to pain.

Overleveraging

Taking on position sizes that exceed account or risk parameters, most often after a losing period, driven by the urge to recover losses in a single trade.

Overleveraging occurs when a trader takes on position sizes that exceed their account or risk parameters. In behavioural trading psychology, overleveraging is almost always post-loss. The emotional driver is recovery urgency: the trader believes a single larger trade can erase previous losses, rather than grinding back through disciplined sizing.

Behavioural Trigger

A detectable pattern in trading activity that signals a shift from strategic to emotional decision-making. Discentra monitors six specific triggers in real time.

A behavioural trigger, in Discentra's framework, is a detectable pattern in trading activity that signals a shift from strategic to emotional decision-making. A losing trade is an event. Three losing trades followed by a position twice the trader's normal size is a trigger. The distinction matters because triggers have predictive value: they indicate what is likely to happen next, not what already happened.

Flow State

A period of sustained trading success, often five or more consecutive wins, where overconfidence builds and the trader starts trusting intuition over process.

Flow state in trading is a period of sustained success, often five or more consecutive winning trades, where the trader feels sharp, confident, and in control. Most platforms treat winning streaks as positive. They should not. Flow state is one of Discentra's six monitored triggers because of what happens next.

Loss Aversion

A cognitive bias identified by Kahneman and Tversky where losses are felt roughly twice as intensely as equivalent gains, driving revenge trading and overleveraging.

Loss aversion is a cognitive bias identified by Daniel Kahneman and Amos Tversky in their 1979 prospect theory research. The finding is that losses are felt roughly twice as intensely as equivalent gains. Losing £100 produces more emotional pain than gaining £100 produces pleasure. This asymmetry is not a personality trait or a discipline failure. It is how the human brain processes risk.

Churn

The rate at which active traders stop trading and leave a platform. ~75% of retail traders quit within 90 days, costing institutions $200 to $2,000 per lost trader.

In the context of financial institutions, churn refers to the rate at which active traders stop trading and leave a platform permanently. ~75% of retail traders quit within their first 90 days. For brokerages and prop firms, each departing trader represents $200 to $2,000 in destroyed customer acquisition cost, depending on the channel and geography.

Drawdown

The decline from a peak account balance to a subsequent low, measured as a percentage or absolute value. The metric that ends trading careers and funded accounts.

Drawdown is the decline from a peak account balance to a subsequent low point, measured as a percentage or absolute value. A trader who grows their account from $10,000 to $12,000 and then drops to $10,800 has experienced a 10% drawdown from the peak. Drawdown is the standard measure of risk in trading performance.

Amygdala Hijack

A neurological event where the brain's threat-detection system overrides rational decision-making under acute stress. The mechanism behind tilt and revenge trading.

Amygdala hijack is a term coined by psychologist Daniel Goleman to describe what happens when the amygdala, the brain's threat-detection centre, overwhelms the prefrontal cortex during a perceived threat. The amygdala fires a stress response before the rational brain can evaluate the situation. In evolutionary terms, this kept humans alive. In trading, it destroys accounts.

Intervention Window

The two-to-four-minute gap between a behavioural trigger event and the trader's next damaging action. Inside this window, the outcome can still change.

The intervention window is the two-to-four-minute gap between a trigger event (a significant loss, a drawdown breach, a revenge trade) and the trader's next damaging action. Inside this window, the trader is reachable. After it, the damage is done. This window is the central operating principle of real-time behavioural coaching.

Active Trader

Any trader enrolled in the Discentra coaching cohort during the billing period, regardless of whether a call was triggered.

In Discentra's framework, an active trader is any trader enrolled in the coaching cohort during the billing period, regardless of whether a call was triggered that month. This definition is broader than the industry standard, which typically counts only traders who placed a trade within a given window. The distinction is not bookkeeping. It shapes the entire product philosophy.

Trader Retention

The ability of a financial institution to keep active traders on its platform over time. The inverse of churn, and the metric that separates profitable firms from acquisition treadmills.

Trader retention is the ability of a financial institution to keep active traders on its platform over time. It is the inverse of churn. In an industry where ~75% of retail traders quit within 90 days, retention is the metric that separates profitable institutions from ones running on a treadmill of perpetual re-acquisition.

Consistency Rule

A prop firm payout rule that caps how much of a trader's total profit can come from a single trading day, usually 20% to 50%. A breach delays the payout rather than failing the account.

The consistency rule caps the share of a trader's total profit that can come from a single trading day. The maths is one line: best-day profit divided by total profit, expressed as a percentage. If a trader's best day is $3,500 of an $11,000 total, that is 32%. Most prop firms set the cap somewhere between 20% and 50%. The rule applies during the evaluation, after funding, or both, depending on the firm.

Trailing Drawdown

The maximum-drawdown variant that trails the highest balance an account reaches rather than sitting at a fixed floor. Breaching it ends the funded account.

Trailing drawdown is a maximum-loss limit that follows the highest balance an account reaches, rather than sitting at a fixed level. A static maximum drawdown is measured from the starting balance and does not move. A trailing drawdown starts there too, then ratchets upward as the account makes new highs. The floor chases the peak. This is the distinction the broader drawdown definition introduces at a high level, and it is the one that catches funded traders off guard.

Prop Firm Challenge

The paid evaluation a trader passes to earn a funded account, gated by a profit target, drawdown limits, and time or consistency rules. The point where most trader churn originates.

A prop firm challenge is the paid evaluation that gates access to a funded account. The structure is consistent across the industry: a profit target the trader must reach, a daily drawdown limit and a trailing drawdown limit they cannot breach, and often a minimum number of trading days or a consistency rule. Challenges run in one or two phases. The trader pays a fee, trades the account to the target inside the rules, and either passes to a funded account or fails and starts again.

Overtrading

Trading beyond a plan or edge, by frequency, position size, or session length. The behaviour pattern that tilt most often produces, and one of Discentra's monitored triggers.

Overtrading is trading beyond a plan or a tested edge. It has three common forms. Frequency overtrading is too many trades in a short window, more positions than the strategy calls for. Size overtrading is position sizes that drift above the trader's own baseline. Session overtrading is staying in the market hours past the point where focus and judgement hold. The forms often arrive together, and they share a root: the trader has stopped executing a strategy and started chasing an outcome.

Daily Loss Limit

The maximum a trader can lose in a single day before the account is stopped or the session ends. The first trigger in Discentra's taxonomy, fired on the approach, not the breach.

A daily loss limit is the maximum a trader is permitted to lose within a single trading day. The mechanism differs by venue. At a prop firm, the daily loss limit is a hard rule, and breaching it can end the funded account outright, separate from the trailing drawdown. At a broker or exchange, it is often a self-imposed or platform-offered cap that closes the session or blocks new positions once hit. In both cases the limit exists to stop one bad day from becoming a catastrophic one.

Cortisol

The stress hormone released through the HPA axis after a threat. In trading, it rises behind the adrenaline spike, peaks around 20 to 30 minutes later, and reshapes how a trader prices risk while it stays high.

Cortisol is the stress hormone the body releases through the hypothalamic-pituitary-adrenal axis in response to a threat. In trading, the threat is usually a sudden loss or a fast drawdown. Cortisol is the second of two stress responses, and the order matters. The first is the sympathetic-adrenal-medullary response: adrenaline and noradrenaline release within seconds, heart rate rises, and attention narrows to the threat. Cortisol rises behind it on a slower clock. The two run on separate timescales, and most traders never separate them.
