Analysis Blocks

Analysis blocks process data and produce outputs that can be used by other blocks or entry rules.

Block Types

Value Block

A simple constant value.

Use for: Reference values, thresholds, parameters

oversold_level: 30
overbought_level: 70

Function Block

A single indicator or function call.

Use for: Simple indicators, single calculations

rsi_14: RSI(btc.close, 14)
sma_20: SMA(btc.close, 20)

Compare Block

Compare two values.

Use for: Simple conditions

rsi_oversold: rsi_14 < 30
price_above_ma: btc.close > sma_20

Operators: < > <= >= == !=

Cross Block

Detect when one value crosses another.

Use for: Crossover signals

ma_cross_up: CROSS_ABOVE(fast_ma, slow_ma)
rsi_cross_down: CROSS_BELOW(rsi, 70)

Functions: CROSS_ABOVE(a, b) CROSS_BELOW(a, b)

Logic Block

Combine multiple signals with boolean logic.

Use for: Complex conditions

entry_signal: ma_cross_up AND rsi_oversold

Operators: AND OR NOT

Advanced Block

Multiple named outputs in a single block.

Use for: Related calculations grouped together

outputs:
  fast_ema: EMA(btc.close, 9)
  slow_ema: EMA(btc.close, 21)
  trend_up: fast_ema > slow_ema

Code Block

Custom JavaScript or Python code.

Use for: Complex logic, external data, custom calculations

// Returns: { signal: boolean[], strength: number[] }
const rsi = utils.indicators.RSI(data.get('btc').close, 14);
const signal = rsi.map(v => v < 30);
const strength = rsi.map(v => (30 - v) / 30);
return { signal, strength };

Output Types

Analysis blocks produce two types of outputs:

Numeric Outputs

Numbers used for calculations or conditions:

Indicator values (RSI, MA, etc.)
Prices and levels
Ratios and percentages

Shown with blue color in the editor.

Boolean Outputs (Signals)

True/false values that trigger actions:

Entry conditions
Filter conditions
Alert triggers

Shown with yellow color in the editor.

Referencing Outputs

Reference outputs from other blocks using dot notation:

block_name.output_name

Examples:

signals.cross_up       # Boolean output from 'signals' block
indicators.rsi         # Numeric output from 'indicators' block
btc.close              # Data source column

Lookback

Access previous values using bracket notation:

btc.close[1]    # Previous bar's close
rsi[5]          # RSI value 5 bars ago
signals.up[1]   # Previous bar's signal

Position-Dependent Blocks

⚠️Warning

Position-dependent blocks only evaluate correctly when there's an open position. They show an orange indicator in the editor.

Some blocks use position-aware functions:

entry_price() — Price at entry
bars_since_entry() — Bars since position opened
position_profit_pct() — Current profit percentage

Best Practices

💡Tip

Name blocks descriptively — trend_signals is much better than block1. Your future self will thank you!

Name blocks descriptively (trend_signals, not block1)
Group related calculations in Advanced blocks
Use Code blocks sparingly — expressions are faster
Keep signal logic separate from value calculations
Document complex logic with block descriptions
