In Trinigence, indicators: * never act on their own * are always part of explicit logic * are evaluated deterministically Indicators help answer questions like: * Is the market trending or ranging? * Is momentum increasing or weakening? * Is price overbought or oversold? *** ## Indicators vs logic It’s important to separate **indicators** from **logic**. * **Indicators** produce values or states * **Logic** decides what to do with those values Example: ```text theme={null} RSI(14) > 50 ``` * RSI(14) → indicator * > 50 → logic *** ## Common indicator categories Trinigence supports a wide range of indicator types. EMA, SMA, Supertrend, Moving Averages. RSI, MACD, Stochastic. ATR, Bollinger Bands. Volume, VWAP, OBV. *** ## Indicator outputs Indicators typically output one of the following: * numeric values (e.g. RSI = 62) * directional states (trend up/down) * crossover events * relative comparisons These outputs are then used inside conditions. *** ## Common logic patterns Indicators are combined using logic patterns. Examples: ```text theme={null} EMA(20) > EMA(50) RSI(14) crosses above 50 MACD line crosses above signal ``` Logic patterns include: * comparisons * crossovers * threshold checks * state changes *** ## Multiple indicators together Strategies often combine indicators. Example: ```text theme={null} Go long when: - EMA(20) > EMA(50) - RSI(14) > 50 - MACD > signal ``` More indicators do not automatically mean better strategies. *** ## Indicator parameters Indicator parameters control sensitivity. Examples: * RSI length * EMA period * ATR window Changing parameters can drastically alter behavior, especially across timeframes. *** ## Evaluation timing Indicators are evaluated: * on candle close * on the strategy timeframe * in the order defined by logic Indicator values are not evaluated intrabar by default. *** ## Defaults and assumptions If indicator parameters are: * explicitly defined → used as-is * omitted but standard → ATI applies defaults * ambiguous → ATI asks for clarification See how indicator defaults are inferred. *** ## Common mistakes Redundant indicators often measure the same thing. Indicator behavior changes dramatically with timeframe. Tight parameter tuning often fails out of sample. *** ## Best practices * Start with one indicator * Understand what it measures * Combine indicators intentionally * Validate behavior visually Learn how indicators are used inside logic. *** ## What to read next How indicator outputs become rules. Explore indicator types in detail. How indicators trigger trades. Express indicator logic clearly. Indicators describe the market.\ Logic defines the decision.
