TRADRILL / GLOSSARY
Trading glossary: discipline, psychology, risk & practice
A one-page-per-term trading glossary from Tradrill: each page carries a short definition, the full explanation, observable signs in your own trade log, a practice routine, and FAQs. Terms cover trading discipline, psychology, risk management, simulation practice, and journaling metrics. Educational only — not financial advice.
Trading discipline
Revenge trading报复性交易
Revenge trading is taking a trade whose real purpose is to win back a recent loss rather than to execute a setup — typically with larger size, immediately after the loss, and without the plan that normally governs entries.
Overtrading过度交易
Overtrading is trading more often than your plan justifies — taking entries that your written rules would not authorize — which means paying commissions, spread and attention on trades that were never supposed to exist.
Loss chasing追损
Loss chasing is increasing exposure to a losing idea — adding to a losing position or immediately re-entering it with more size — in order to escape the loss faster rather than because the plan authorizes it.
Daily loss limit每日亏损上限
A daily loss limit is a maximum loss for one trading session, written before the session starts, whose breach ends trading for the day — a pre-commitment that removes the worst decisions from the moment they would be made.
Trading plan交易计划
A trading plan is the written rule set you commit to before trading: which setups you take, how you size and stop them, when you don't trade, and how you review — the single document your journal, limits, and reviews all reference.
Trading psychology
Tilt上头(情绪失控)
Tilt is a state in which emotion — frustration, euphoria, impatience — degrades your decision quality below your own baseline; the term comes from poker and is now standard trading vocabulary.
FOMO踏空焦虑(害怕错过)
FOMO (fear of missing out) is entering a trade because the move is visibly happening and the pain of missing it outweighs the setup's actual quality — chasing a train that has left, at the worst available price.
Confirmation bias确认偏误
Confirmation bias is the tendency to seek, notice, and credit evidence supporting what you already believe or hold — in trading, it is why a losing position suddenly has "so many reasons" to keep, and why the bull case always looks complete while you are long.
Risk management
Drawdown回撤
A drawdown is the decline in account (or strategy) equity from its most recent peak to the subsequent trough, normally expressed as a percentage of that peak.
Position sizing仓位管理
Position sizing is the rule that decides how large a position to take: risk a fixed fraction of account equity to the stop, so size = risk budget ÷ entry-to-stop distance — independent of conviction.
Stop-loss order止损单
A stop-loss is an order that exits a position when price reaches a level chosen in advance — the level at which the reason for the trade is wrong — converting an open-ended loss into a fixed, planned one.
Leverage杠杆
Leverage is controlling a position worth more than the capital you commit, via margin or derivatives; it multiplies both directions of every price move and transforms small mistakes into account-level events.
Margin call追加保证金(强平)
A margin call is the broker's demand to add collateral (or the forced reduction of positions) when floating losses on leveraged positions consume the margin you posted; at liquidation, positions close at the market regardless of your plan.
Averaging down摊低成本
Averaging down is adding to an existing losing position so the average entry price falls; it is a legitimate tactic only when the addition was fully written before the first entry — size, trigger, and an invalidation that still exists.
Practice & simulation
Paper trading模拟交易
Paper trading is placing simulated trades with virtual funds — real prices, fake money — used to rehearse a written decision process (entries, sizing, stops, reviews) before any capital is at risk.
Bar replayK 线回放
Bar replay is a simulator mode that redraws historical price charts one bar at a time, hiding the future, so you can practice entries, exits, and management decisions on real past markets without hindsight bias.
Backtesting回测
Backtesting is applying a completely specified set of trading rules to historical market data to estimate how those rules would have performed — an estimate whose quality depends entirely on the rules being mechanical and the test avoiding hindsight.
Deliberate practice刻意练习
Deliberate practice is structured repetition with four properties: a narrow specific target, immediate feedback, difficulty just beyond current ability, and full attention — the framework that converts practice hours into skill instead of familiarity.
Trading routine交易例程
A trading routine is the fixed sequence of activities around trading — pre-session preparation, in-session execution rules, post-session logging and review — that makes good behavior the default instead of a daily act of willpower.
Journaling & metrics
R-multipleR 倍数
An R-multiple is a trade's profit or loss divided by the amount initially risked on it — the entry-to-stop distance times position size — so results are stated in units of risk (R) instead of currency.
Risk-reward ratio风险回报比
The risk-reward ratio compares a trade's planned maximum loss (entry to stop) with its planned target (entry to objective) — 1:2 means risking one unit to attempt two — and it is written before entry, unlike the realized R-multiple.
Win rate胜率
Win rate is the percentage of closed trades that ended positive; alone it says nothing about profitability — it only becomes meaningful paired with the average size of wins and losses (average R).
Expectancy期望值(每笔期望)
Expectancy is the average result per trade, expressed in R: (win rate × average win in R) − (loss rate × average loss in R); a positive number over a large sample is the arithmetic definition of a working strategy.
Trading journal交易日志
A trading journal is a per-trade record of the decision — setup, plan, size, stop, reason, screenshots, outcome in R — kept so that reviews and metrics measure your actual process instead of memory's reconstruction of it.
Slippage滑点
Slippage is the difference between the price at which you expected to execute and the price you actually got; it is a real trading cost that appears in fast or thin markets and is often invisible in simulators.
Practice this term in simulation
Tradrill is an AI trading education platform where traders practice in a simulated trading terminal and get AI behavioral feedback that quantifies the real cost of habits like revenge trading, loss chasing and overtrading — with structured courses and weekly discipline reports, and no trade signals or auto-trading.
