Signal Examples

This page showcases realistic and powerful signal examples built with the StockBeat DSL.
The goal is to demonstrate how simple primitives compose into professional-grade trading logic.

All examples are written exactly as users would define them in StockBeat.

1. RSI Oversold Bounce (Classic Mean Reversion)

Idea:
Enter when RSI becomes oversold and starts recovering.

close().rsi(14).below(30).held_for(3)

Explanation:

  • RSI(14) drops below 30
  • Condition holds for 3 consecutive bars
  • Filters out single-bar spikes

Use case:

Mean-reversion strategies in range-bound markets.

2. Moving Average Crossover (Trend Following)

Idea:
Detect when short-term momentum overtakes long-term trend.

close().ema(9).crosses_above(close().ema(21))

Explanation:

  • Fast EMA crosses above slow EMA
  • Evaluated only at the crossing point

Use case:

Trend entry confirmation.

3. Momentum + Trend Confirmation

Idea: Only enter when momentum and trend agree.

close().ema(9).crosses_above(close().ema(21))
.and(close().rsi(14).above(50))

Explanation:

  • Crossover confirms trend
  • RSI above 50 confirms bullish momentum

Use case: Avoid false breakouts.

4. Volatility Expansion Breakout

Idea: Trade breakouts only when volatility expands.

close().crosses_above(close().bb(20, 2, up))
.and(close().bb(20, 2, avg).rising(5))

Explanation:

  • Price breaks above upper Bollinger Band
  • Band width rising → volatility expansion

Use case: Breakout strategies with volatility filter.

5. MACD Reversal After Consolidation

Idea: Wait for MACD signal after a quiet period.

close().macd(12, 26, 9).gt(0).within(3)

Explanation:

  • Histogram crosses above zero
  • Signal must occur within last 3 bars

Use case: Early trend reversals.

6. Multi-Condition Entry With Time Constraint

Idea: Require confirmation within a time window.

close().ema(9).crosses_above(ema(21))
.and(close().rsi(14).above(50).within(2))

Explanation:

  • RSI confirmation must happen within 2 bars of crossover
  • Prevents late entries

Use case: Tighter execution rules.

7. Failed Breakout (Contrarian Setup)

Idea: Detect failed breakout and fade the move.

close().crosses_above(close().ema(50))
.and(close().lt(close().ema(50)).within(2))

Explanation:

  • Price breaks resistance
  • Quickly falls back below → failure

Use case: False breakout detection.

8. Trend Exhaustion Warning

Idea: Strong trend losing momentum.

close().rsi(14).falling(5)
.and(close().gt(close().sma(200)))

Explanation:

  • RSI falling for 5 bars
  • Price still above long-term trend

Use case: Prepare exits or tighten stops.

9. Signal With Explicit Negation

Idea: Enter trend-following trades only when momentum is strong and the market is not in an expansionary (high-volatility) phase, reducing the risk of false breakouts and whipsaws.

close().ema(9).crosses_above(ema(21))
.and(close().rsi(14).above(50))
.and(close().ema(5).sub(close().ema(20)).rising(3).not())

Explanation:

  • Avoid entries during abnormal volatility

Use case: Risk control.

10. Persistent Trend Confirmation Alarm

Idea: Detect a sustained trend shift confirmed by momentum, avoiding short-lived spikes and noisy crossovers.

close().ema(9).crosses_above(close().ema(21))
.and(close().rsi(14).above(55)).held_for(2)

Explanation:

  • Combines short-term and medium-term EMA crossover to identify trend direction
  • RSI threshold confirms momentum strength
  • held_for(2) requires the condition to persist across multiple bars, filtering out transient signals

Use Case: Robust alerts suitable for live monitoring and automated notification workflows.
