The Start Bots Signal category describes signals and indicators that can start a trading bot. One of the technical indicators is Momentum.
When creating or editing any bot, there is a Start signal builder block at the bottom of settings. You can choose individual indicators, ready-made presets, and their combinations. Conditions are grouped: AND inside a group, OR between groups. The same indicator can be configured in different ways - for Long and Short, for breakouts and bounces, for level comparisons and for crosses.
What is Momentum
Momentum is one of the simplest and most direct measures of how fast price is changing. It shows how much the current price differs from the price N periods ago. If the asset rose over that interval, Momentum is positive; if it fell, Momentum is negative.
Unlike oscillators on a fixed scale, Momentum is unbounded: on volatile assets values can be large in absolute terms. The zero line is the key reference: above zero, bullish impulse dominates over the selected period; below zero, bearish impulse dominates. In the ELIXOAI start signal builder, Momentum is used as an automatic bot start condition - when the indicator crosses zero or stays above/below a threshold.
Momentum highlights acceleration: a sharp price rise quickly pushes the line into positive territory; fading trend pulls it back toward zero. Traders often combine it with trend filters (EMA, price position) - especially in sideways markets where zero crosses produce many false signals.
Momentum vs RSI and MACD
All three tools relate to impulse, but measure it differently:
- RSI normalizes movement into a 0–100 scale by comparing average gains and losses. RSI answers “how strong was the move relative to recent history,” not “how many points did price change.” Levels 30/70 mark oversold and overbought zones.
- MACD is built as the difference between two exponential moving averages (typically 12 and 26 EMA) and shows convergence/divergence of trend averages. MACD is smoother and slower than “raw” Momentum; it is often used with a signal line for crosses.
- Momentum is a direct arithmetic difference: Close − Close[N]. No normalization, no extra smoothing. It reacts faster but is sensitive to absolute price scale and instrument volatility. The zero line replaces RSI’s “50 level” or MACD’s zero line.
How Momentum works
The calculation is straightforward - that is the point:
Momentum = Close − Close[period], where Close is the current candle close and Close[period] is the close N candles ago.
- Momentum > 0 - price is higher than N periods ago; bullish impulse over the interval.
- Momentum < 0 - price is lower than N periods ago; bearish impulse.
- Momentum = 0 - price equals the level from N periods ago; neutral impulse, equilibrium point.
In the builder you set a comparison condition: “Momentum crosses above 0,” “Momentum greater than 0,” “Momentum less than 0,” and so on. The system fetches live Momentum from the exchange via TAAPI and checks the condition on your timeframe - at candle close or every minute.
Period parameter
- Range: 1 to 300.
- Default: 10 - balanced for 15m–1h; a classic short-term impulse setting.
- Short period (3–5): Momentum reacts faster, more zero crosses, more noise. Useful on 5m for scalping - catch short impulse spikes.
- Long period (20–50): smoother Momentum, less frequent sign changes. Better for 1h–4h swing - fewer but more sustained impulse signals.
Momentum(10) on 5m and Momentum(10) on 4h are different indicators. When changing timeframe, revisit both period and signal type (cross vs gt/lt).
Ready-made presets in the builder
The builder offers one Momentum preset with default settings. You can fully customize it: different operator, level, period, or timeframe.
Momentum cross_up 0 - bullish impulse (mom)
Default condition: Momentum crosses level 0 from below to above (cross up) on the selected timeframe (15m interval, period 10, check at bar close).
A Long signal on impulse turning positive: price is rising faster than N periods ago - Momentum moved from negative or neutral into positive. Unlike “Momentum > 0,” the cross captures the transition moment, not just current position above zero. For Short, set operator “crosses below” and target 0.
Available operators- Crosses above (cross up): Momentum was below the level and moved above. Classic Long setup - cross up 0: start of positive impulse.
- Crosses below (cross down): Momentum was above the level and dropped below. Short signal - cross down 0: impulse turned negative.
- Greater than (gt): Momentum is strictly above the level right now. E.g. Momentum > 0 - sustained bullish impulse without requiring a fresh cross.
- Less than (lt): Momentum is strictly below the level. Momentum < 0 - clear bearish impulse, useful for Short filters.
- Greater or equal (gte): Momentum is at or above the threshold. Handy for “Momentum ≥ 0” filter on a higher timeframe.
- Less or equal (lte): Momentum is at or below the threshold. Bearish context filter: Momentum ≤ 0 on 4h.
Zero is Momentum’s main reference: cross up 0 means price rose above the level from N periods ago; cross down 0 means it fell below. In a strong trend Momentum can stay above or below zero for a long time - then gt/lt gives earlier entry while cross gives a more precise impulse shift.
General builder settings
- Timeframe (interval): 1m, 5m, 15m, 30m, 1h, 4h, 1d. Shorter intervals give more signals but more noise. Swing bots often use 1h–4h; scalping uses 5m–15m.
- Check mode: At candle close checks after the candle closes - fewer false triggers. Every minute checks inside the current candle - faster reaction, higher false-start risk.
- Operator: greater than, less than, crosses above, crosses below, greater or equal, and others define how the indicator value is compared to the target.
- Target value: a number (e.g. 30 for RSI), an indicator line (e.g. %D for Stochastic), or price (for Bollinger Bands).
- Condition groups: up to 3 groups with up to 5 conditions each. Example: group 1 - RSI < 30 AND price < lower band; group 2 - Stochastic < 20. The bot starts if group 1 OR group 2 is satisfied.
Setup examples for different strategies
Scalping: period 5 on 5m–15m
Goal: frequent starts on short impulses.
Long: mom preset, cross up 0, 5m timeframe, period 5, check at bar close.
Short: cross down 0, same settings.
Filter: add price above EMA 20 on the same 5m - fewer false crosses in a range.
Swing: period 20 on 1h–4h
Goal: fewer but more meaningful moves.
Long: Momentum cross up 0 on 4h, period 20, check at close - bot starts on a sustained impulse shift.
Short: cross down 0 on 4h, period 20.
Period 20 on a higher TF smooths noise and signals closer to a “real” trend turn.
Trend confirmation
Goal: Long only when impulse and trend align.
Group 1: Momentum cross up 0 on 15m AND close price above EMA 50 on the same 15m.
Short: Momentum cross down 0 AND price below EMA 50.
EMA shows direction; Momentum confirms the move is accelerating.
Breakout
Goal: start the bot on impulse after consolidation.
Long: Momentum gt 0 on 15m (period 10) AND price cross up upper Bollinger Band (20, 2) on the same interval.
Short: Momentum lt 0 AND price below lower BBands.
Momentum gt 0 confirms the breakout is backed by speed, not a random spike.
Momentum + EMA
Long: price cross up EMA 20 on 15m AND Momentum cross up 0 on the same 15m - double confirmation: both price and impulse turned up.
Short: price cross down EMA 20 AND Momentum cross down 0.
Alternative: Momentum gt 0 AND price > EMA 50 on 1h - trend Long on sustained impulse.
Short on impulse shift
Condition: Momentum cross down 0 or Momentum < 0, period 10, 15m, check at close.
Filter: RSI > 65 in the same group - short after overbought with fading impulse confirmation.
Fits short grids at local peaks when upward momentum slows.
Strong impulse (gt filter)
Long: Momentum gt 0 on 1h, period 10 - bot starts only with clear positive impulse, without waiting for a cross.
Short: Momentum lt 0 on 1h.
Useful in trends where cross up 0 already happened but impulse still favors you. Downside - later entry vs cross.
Pullback in trend
Group 1: Momentum on 4h greater than 0 (period 20) AND Momentum cross up 0 on 15m (period 10).
Logic: higher TF shows sustained bullish impulse; lower TF catches resumption after a short correction. Fewer false starts against the global trend.
Momentum + RSI
Long: RSI cross up 30 on 15m AND Momentum cross up 0 on 15m - oscillator and “raw” speed aligned.
Short: RSI cross down 70 AND Momentum cross down 0.
RSI catches oversold/overbought; Momentum checks that price actually accelerated in the right direction.
Multi-timeframe
Long: Momentum on 4h ≥ 0 (separate condition, gte, period 20) AND Momentum cross up 0 on 15m (period 10).
Short: Momentum 4h ≤ 0 AND Momentum cross down 0 on 15m.
This avoids buying every local Momentum spike against global bearish impulse on the higher interval.
DCA on pullback
Long: Momentum cross up 0 on 1h (period 14) AND RSI < 45 on 1h - impulse bounce from weakness without extreme oversold.
Short: Momentum cross down 0 AND RSI > 55.
For a DCA bot on trend pullbacks, cross up 0 is softer than strict RSI < 30 - fewer false entries during ongoing drops.
Condition groups: practical example
Bot with two Long scenarios:
Group 1: Momentum cross up 0 on 15m AND price > EMA 50 - trend impulse resumption.
Group 2: Momentum gt 0 on 1h (period 20) AND RSI < 40 on 15m - bounce with confirmed higher-TF impulse.
Groups combined with OR: either scenario can start the bot. Configure Short symmetrically (cross down 0, Momentum lt 0).
Tip
In a ranging market Momentum constantly oscillates around zero: cross up 0 and cross down 0 trigger often and produce false bot starts. Increase period (20 instead of 5), add an EMA filter, or require Momentum ≥ 0 on a higher timeframe. In pure chop Momentum is a weak standalone signal - combine with Bollinger breakouts or trend context. Use check at bar close to ignore intrabar noise.
