Comparison, range, trend, pattern, logic, time, volume, volatility, statistical. **Conditions are the predicates that turn indicator outputs into 'fire / don't fire' decisions.** The SignalEditor exposes 41 condition types across 9 categories — wide enough that almost any tradable thesis can be expressed without composing custom logic. ## Categories at a glance | Category | Examples | Use for | | --------------- | ------------------------------------------------- | ----------------------------------------- | | **Comparison** | greater-than, crossover, crossunder | Foundational threshold and crossing logic | | **Range** | within-range, outside-range, between | Bracket-based decisions | | **Trend** | rising, falling, flat over N bars | Direction confirmation over a window | | **Pattern** | higher-highs, breakout, double-bottom | Pre-built chart patterns | | **Logic** | AND, OR, NOT, XOR | Composing multiple conditions | | **Time** | within-window, after-time, before-time | Trading hour gating | | **Volume** | above-average, surge, dry-up | Volume confirmation | | **Volatility** | within-band, outside-band, contracting, expanding | Vol-regime detection | | **Statistical** | z-score-above, percentile-threshold | Rigorous mean-reversion | ## Comparison — the foundation `A > B`, `A < B`. Threshold logic. RSI > 70, price > EMA(50), volume > average × 2, etc. Same as above with edge cases included. Exact equality. Rare for continuous values; useful for indicator outputs that produce discrete states. `A` crosses **above** `B` on the current bar. Detects the moment of crossing. Best for: EMA cross signals (EMA20 crosses above EMA50), MACD signal-line crosses, RSI crossing back above 30 from oversold. `A` crosses **below** `B` on the current bar. Best for: exit signals after a crossover-driven entry. ## Range — bracket decisions Value is between low and high bounds (inclusive). Useful for "RSI is between 30 and 70" (neutral zone). Value is below low OR above high. The complement of within-range. Value is between two indicator values (not fixed numbers). Useful for "price is between EMA(20) and EMA(50)" (in transition zone). ## Trend — direction confirmation Indicator value is consistently increasing over the last N bars. Use for "EMA is rising" (uptrend confirmation). Value consistently decreasing. Value within a tight range over N bars. Useful for "low volatility" detection alongside Bollinger Width. ## Pattern — pre-built chart patterns The recent N highs are progressively higher. Uptrend confirmation. The recent N lows are progressively lower. Downtrend confirmation. Two recent lows at similar price levels with a peak between. Reversal pattern. Price closes above a recent N-bar high. Classic breakout signal. Pair with volume surge for confirmation (see Volume conditions). Price closes below a recent N-bar low. Breakdown signal. ## Logic — composing conditions Both sub-conditions hold simultaneously. The most-used composer. Example: `RSI < 30 AND price < EMA(50)` — RSI oversold and price below trend. Either sub-condition holds. Example for an exit: "RSI > 70 OR price > EMA(50)" — exit if either condition triggers. Inverts a sub-condition. Useful for "not in range" logic. Exactly one of two sub-conditions holds. Niche but occasionally useful for state-detection. ## Time — trading hour gating Current time is within a specified window (e.g., `09:00–17:00`). Useful for trading only during high-liquidity hours. Current time is after a threshold time. Useful for "no trading before market open." Current time is before a threshold time. Useful for "no trading after Friday 23:00." **Time-based filtering is underused in crypto.** Many operators don't think to filter by time-of-day, but crypto markets do have rhythms — London open, US open, weekend low-liquidity. Time conditions help avoid bad-fill periods. ## Volume — confirmation conditions Current volume is above its N-bar average. Confirms participation behind a price move. Current volume is N times the recent average (e.g., 2x or 3x). Detects unusual activity. Current volume is below a threshold. Detects low-conviction periods. ## Volatility — regime detection Price is within Bollinger/Keltner bands. Normal volatility regime. Price has broken outside bands. Tail-event detection. Bollinger Width is decreasing — squeeze setup forming. Bollinger Width is increasing — volatility rising. ## Statistical — rigorous thresholds Indicator's z-score (normalized deviation from mean) above/below a threshold. Tail-event detection tied to actual recent distribution. Example: "z-score-above 2" fires when value is more than 2 standard deviations above its recent mean. Indicator's percentile rank over recent N bars meets a threshold. Example: "Bollinger Width is in the bottom 10th percentile" = squeeze setup. ## Best practices for condition design * ✅ **Start with simple comparisons** — `>`, `<`, `crossover`, `crossunder`. Easy to reason about. * ✅ **Add a trend filter to mean-reversion** — don't catch falling knives. * ✅ **Use ADX > 25 for trend-following** — only act when trend is real. * ✅ **Limit to 2–3 conditions per AND** — overfitting risk with more. * ✅ **Time-window filter for low-liquidity exclusion** — avoid weekend / overnight bad fills. * ✅ **Volume-surge confirmation for breakouts** — filters fakeouts. * ✅ **Statistical thresholds (z-score, percentile) for rigorous setups** — better than fixed numbers. * ✅ **Mirror entry conditions for exit** — symmetric logic for clean state management. * ✅ **Test each condition's contribution** — does adding it actually improve outcomes? ## What's next The 136 indicators that feed into conditions.
