Expression Schema — Detailed JSON Reference

Per-type schema for every element type available on this SaaS. Use this when generating expression JSON with an AI assistant. SaaS-forbidden types (Lua, C++ operands, account/position metrics) are omitted — see nlp-help §15. For the higher-level NLP path see nlp-help.html.

1. Base Fields (every expression)

Each expression has a left side, a comparison operator, and a right side. Field names use the prefix Expression_left_ or Expression_right_. Plus expression-level fields (ExpressionName, Symbols, etc.).

{
  "ExpressionName": "unique_name_within_account",    // required, unique
  "Expression_left_Name": "descriptive_label_for_left",
  "Expression_left_ElementType": "<one of the type IDs listed below>",
  "Expression_left_ElementValue": "<type-specific value>",
  "Expression_left_operation": "<",                  // see §3 Operators
  "Expression_right_ElementType": "FixedVal",
  "Expression_right_ElementValue": "30",
  "Expression_right_Name": "descriptive_label_for_right",
  "Symbols": ["EURUSD"],                            // exactly ONE symbol per expression
  "tags": ["alert"]                                // "alert" | "helper"
}

2. Common Optional Keys

These keys can appear on either side when configured. Most are mutually exclusive or only meaningful for certain element types — see the per-type sections for which apply.

  "Expression_left_UseCurrentObject": true,
  "Expression_left_Index": 1,
  "Expression_left_TickRevVal": 50,
  "Expression_left_WaveName": "A",

4. TA_Indicators

200+ technical indicators (RSI, SMA, EMA, MACD, BBANDS, ATR, STOCH, ADX, ICHIMOKU, …). Param fields use Size1, Size2, Size3, and Double1/Double2/Double3 for floating-point params (ALMA offset/sigma, JMA phase, etc.).

{
  "ExpressionName": "RSI_Oversold_5m_EURUSD",
  "Expression_left_ElementType": "TA_Indicators",

  "Expression_left_Name": "RSI_Oversold_5m_EURUSD",
  "Expression_left_Frame": "5Min",                    // see §24.6 Timeframes
  "Expression_left_Size1": 14,                        // first numeric param (RSI period)
  "Expression_left_operation": "<",

  "Expression_right_ElementValue": "30",
  "Expression_right_Name": "RSI_Oversold_5m_EURUSD",
  "Symbols": ["EURUSD"],
  "tags": ["alert"]
}

Optional fields for multi-param indicators: Size2, Size3, Double1 (e.g. ALMA offset), Double2 (e.g. ALMA sigma), Subfield (MACD→Signal/Macd/Hist, BBANDS→Upper Band/Middle Band/Lower Band, STOCH→SlowK/SlowD, ICHIMOKU→Tenkan/Kijun/Senkou A/Senkou B/Chikou, etc. — see INDICATOR_SUBFIELDS at /api/builder/schema.js).

Timeframes

Valid Frame values: "1Min", "2Min", "5Min", "15Min", "30Min", "1Hour", "4Hour", "Daily", "Weekly".

Indicator default params & labels

The complete list of 232 indicator default-params and 179 param labels is served live at /api/builder/schema.js — fields DEFAULT_PARAMS and INDICATOR_PARAM_LABELS. Examples:

For indicators not listed above, fetch the live schema and look up the indicator in DEFAULT_PARAMS / INDICATOR_PARAM_LABELS / INDICATOR_SUBFIELDS.

}

12. PricePattern / PricePatterns

Two related types. PricePattern is the standalone form. PricePatterns (plural) is the legacy form that the serializer rewrites to UserExpression on the wire — see §23.

PricePattern (preferred)

{
  "ExpressionName": "DoubleBottom_5m_EURUSD",
  "Expression_left_ElementType": "PricePattern",
  "Expression_left_ElementValue": "DoubleBottom",         // all 46 patterns in §24.3
  "Expression_left_Name": "DoubleBottom_5m_EURUSD",
  "Expression_left_FieldName": "OnFormation",           // PRICE_PATTERN_FIELDS — see §24.4
  "Expression_left_Frame": "5Min",
  "Expression_left_TickRevVal": 50,
  "Expression_left_LegIndex": 1,
  "Expression_left_operation": "=",
  "Expression_right_ElementType": "FixedVal",
  "Expression_right_ElementValue": "1",
  "Expression_right_Name": "DoubleBottom_5m_EURUSD",
  "Symbols": ["EURUSD"],
  "tags": ["alert"]
}

PricePatterns (legacy, rewrites to UserExpression)

{
  "Expression_left_ElementType": "UserExpression",          // rewritten by the serializer
  "Expression_left_ElementValue": "DOUBLE_BOTTOM_50ticks_FINAL",  // rewritten: <pattern>_<TickRevVal>ticks_FINAL
  "Expression_left_TickRevVal": 50
}

13. ABCPattern

{
  "ExpressionName": "ABC_Distance_above_10_EURUSD",
  "Expression_left_ElementType": "ABCPattern",
  "Expression_left_ElementValue": "Distance",              // ABC_FIELDS — see §24.5
  "Expression_left_Name": "ABC_Distance_above_10_EURUSD",
  "Expression_left_NumElements": "3",                   // ABCPattern is the ONLY type that emits NumElements
  "Expression_left_TickRevVal": 50,
  "Expression_left_WaveName": "A",                      // ABC_WAVES: Current, AB, BC, CD, ...
  "Expression_left_operation": ">",
  "Expression_right_ElementType": "FixedVal",
  "Expression_right_ElementValue": "10",
  "Expression_right_Name": "ABC_Distance_above_10_EURUSD",
  "Symbols": ["EURUSD"],
  "tags": ["alert"]
}

14. PriceMoveObject

Subscribes to price-move events fired by another saved expression. Required: priceMoveSourceUserExp must name a saved UserExpression. The serializer rewrites the wire format to UserExpression.

{
  "ExpressionName": "PriceMove_Bid_100_Up_EURUSD",
  "Expression_left_ElementType": "UserExpression",          // rewritten by serializer
  "Expression_left_ElementValue": "MY_SOURCE_USER_EXPRESSION", // must be a saved UserExpression name
  "Expression_left_Name": "PriceMove_Bid_100_Up_EURUSD",
  "Expression_left_FieldName": "Bid",                   // PRICE_MOVE_FIELDS — see §24.5
  "Expression_left_PriceMoveValue": 100,
  "Expression_left_PriceMoveDirection": "Up",
  "Expression_left_TimeLimitSeconds": 60,
  "Expression_left_operation": "=",
  "Expression_right_ElementType": "FixedVal",
  "Expression_right_ElementValue": "1",
  "Expression_right_Name": "PriceMove_Bid_100_Up_EURUSD",
  "Symbols": ["EURUSD"],
  "tags": ["alert"]
}

15. DateValue / HourValue / SideValue

DateValue

{
  "ExpressionName": "DayOfWeek_eq_3_BTC",
  "Expression_left_ElementType": "DateValue",
  "Expression_left_ElementValue": "DayOfWeek",             // DATE_VALUES: CurrentSysDateTime, CurrentSysDay, CurrentSysTime, DayOfWeek
  "Expression_left_Name": "DayOfWeek_eq_3_BTC",
  "Expression_left_operation": "=",
  "Expression_right_ElementType": "FixedVal",
  "Expression_right_ElementValue": "3",                   // 3 = Wednesday (Sun=0..Sat=6)
  "Expression_right_Name": "DayOfWeek_eq_3_BTC",
  "Symbols": ["BTCUSDT"],
  "tags": ["alert"]
}

HourValue

{
  "ExpressionName": "AfterHour_14_EURUSD",
  "Expression_left_ElementType": "DateValue",
  "Expression_left_ElementValue": "CurrentSysTime",
  "Expression_left_Name": "AfterHour_14_EURUSD",
  "Expression_left_operation": ">=",
  "Expression_right_ElementType": "HourValue",
  "Expression_right_ElementValue": "14:00",                // HOUR_VALUES: "00:00" .. "24:00" (25 hourly slots)
  "Expression_right_Name": "AfterHour_14_EURUSD",
  "Symbols": ["EURUSD"],
  "tags": ["alert"]
}

SideValue

{
  "ExpressionName": "Side_eq_BID_EURUSD",
  "Expression_left_ElementType": "SideValue",
  "Expression_left_ElementValue": "BID",                    // SIDE_VALUES: "BID", "ASK", "NO SIDE"
  "Expression_left_Name": "Side_eq_BID_EURUSD",
  "Expression_left_operation": "=",
  "Expression_right_ElementType": "FixedVal",
  "Expression_right_ElementValue": "1",
  "Expression_right_Name": "Side_eq_BID_EURUSD",
  "Symbols": ["EURUSD"],
  "tags": ["alert"]
}

16. UserExpression (composition / reuse)

Reference another saved expression by name. This is how you compose deep trees. No depth limit.

{
  "ExpressionName": "Buy_Signal_Combined_EURUSD",
  "Expression_left_ElementType": "UserExpression",
  "Expression_left_ElementValue": "RSI_Oversold_5m_EURUSD",  // must be a saved expression's unique name
  "Expression_left_Name": "Buy_Signal_Combined_EURUSD",
  "Expression_left_ApplyChart": true,                  // optional: render on chart
  "Expression_left_UseLineChart": true,                 // optional: line-chart variant
  "Expression_left_operation": "AND",
  "Expression_right_ElementType": "UserExpression",
  "Expression_right_ElementValue": "Trend_Up_Daily_EURUSD",
  "Expression_right_Name": "Buy_Signal_Combined_EURUSD",
  "Symbols": ["EURUSD"],
  "tags": ["alert"]
}

Variant — render in sub-chart pane:

{
  "Expression_left_ApplyChart": true,
  "Expression_left_UseSubChart": true
}

helper "Trend_Up_Daily" = SMA(50) > SMA(200) on Daily
helper "RSI_Oversold_5m" = RSI(14) < 30 on 5Min
helper "Trend_AND_Oversold" = UserExpression("Trend_Up_Daily") AND UserExpression("RSI_Oversold_5m")
alert  "Buy_Signal" = UserExpression("Trend_AND_Oversold") = true

17. Fundamental

{
  "ExpressionName": "PE_Ratio_above_30_AAPL",
  "Expression_left_ElementType": "Fundamental",
  "Expression_left_ElementValue": "PE_RATIO",              // FUNDAMENTAL_FIELDS — see §24.5 (87 fields)
  "Expression_left_Name": "PE_Ratio_above_30_AAPL",
  "Expression_left_FieldName": "PE_RATIO",
  "Expression_left_ReportYear": 2024,                   // emitted when fundamentalFieldYear != 0
  "Expression_left_operation": ">",
  "Expression_right_ElementType": "FixedVal",
  "Expression_right_ElementValue": "30",
  "Expression_right_Name": "PE_Ratio_above_30_AAPL",
  "Symbols": ["AAPL"],
  "tags": ["alert"]
}

Alternative — use the bar's quote-date instead of a fixed year:

{
  "Expression_left_UseQuoteDate": true
}

20. Reducers / History / Series

Wrap any side with a reducer to compute aggregates over a lookback window. Multiple flags can stack — they correspond to the modifier layer in the builder UI.

Moving Average

{
  "Expression_left_UseMA": true,
  "Expression_left_numElement": 20                       // window size
}

EMA / TotalSum / StandardDev / MeanDev / MinSeries

{
  "Expression_left_UseEMA": true,                        // or UseTotalSum, UseStandardDev, UseMeanDev, UseMinSeries
  "Expression_left_collectionSize": 20,                  // window size (some flags use this)
  "Expression_left_numElement": 20                       // window size (others use this — see notes)
}

Standard Deviation Flags

{
  "Expression_left_UseSD": true,                         // emit BOTH for standard deviation
  "Expression_left_UseStandardDev": true
}

History Element (index into past values)

{
  "Expression_left_UseHistoryElem": true,
  "Expression_left_historyIndex": 3,                   // 0 = current, 1 = previous bar, etc.
  "Expression_left_collectionSize": 4                   // lookback depth
}

Max / Min Series

{
  "Expression_left_UseMaxSeries": true,
  "Expression_left_UseSeriesLocation": true             // optional: return bar index of the max
}

{
  "Expression_left_UseMinSeries": true,
  "Expression_left_UseSeriesDate": true                 // optional: return date of the min
}

{
  "Expression_left_UseNextMinMax": 1                       // numeric: 0=disabled, 1=next, 2=after-next, ...
}

21. Unary Modifiers

Wrap any side with a unary operator. Applied after the operand is resolved, before the comparison.

{
  "Expression_left_applyUnaryNot": true,                  // boolean negation: !value
  "Expression_left_applySqrt": true,                      // sqrt(value)
  "Expression_left_applyPow": true,                       // value^2
  "Expression_left_applyAbs": true                        // abs(value)
}

22. Repeat Conditions / Time Limit

Require the condition to hold for a window of bars before firing — stronger confirmation, fewer false signals.

{
  "Expression_left_repeatMinXbars": 2,                   // must be true for at least N bars
  "Expression_left_repeatMaxXbars": 5,                   // at most M bars (window)
  "Expression_left_repeatMinMaxXbarsFrame": "5Min",        // the bar timeframe to count on
  "Expression_left_TimeLimitInSeconds": 60                // alternative: time-window in seconds
}

23. Implementation Notes & Gotchas

• PricePatterns (plural) is rewritten by the serializer to ElementType="UserExpression" with ElementValue="<pattern>_<TickRevVal>ticks_FINAL". If you mean the standalone form, use PricePattern (singular).
• PriceMoveObject is rewritten by the serializer to ElementType="UserExpression" with ElementValue=<priceMoveSourceUserExp>. The priceMoveSourceUserExp field MUST be the name of a saved UserExpression.
• ABCPattern is the only branch that emits NumElements. Don't emit it elsewhere.
• UseSD and UseStandardDev must both be emitted for standard deviation.
• Several fields are mutually exclusive because the serializer uses if/elif chains. For example, only one of UseMA / UseEMA / UseTotalSum / UseStandardDev / UseMeanDev / UseMinSeries takes effect per side.
• Some field names are intentionally inconsistent with case — the serializer preserves legacy parser expectations:
  • size (lowercase) for Bollinger Bands
  • Size (uppercase) for Keltner Channel
  • useOpenBar (lowercase u)
  • frameIn (camelCase) for Renko / Heikin
• The tags array has two canonical values: "alert" (deployable, fires notifications) and "helper" (reusable building block, never fires on its own). Mix only when intentional.
• Each expression watches exactly one symbol via Symbols: ["..."]. Multi-symbol coverage = one expression per symbol.
• Expression names are unique within an account — that's the handle UserExpression uses to reference them.

24. Full Catalogs (every selectable value)

Authoritative enumeration of every value you can put in ElementValue for the pattern/indicator types. Sourced from the live /api/builder/schema.js endpoint — AIs that can fetch URLs should curl that endpoint for the source of truth; the static lists below are mirrored for offline reading.

24.1 TA_Indicators — 233 indicators across 14 categories

Use the indicator name (case as shown) as Expression_*_ElementValue. For per-indicator defaults (Size1, Size2, Double1, etc.) and labels, fetch DEFAULT_PARAMS + INDICATOR_PARAM_LABELS from the schema endpoint.
