CMF Node
Chaikin Money Flow
Overview
Chaikin Money Flow (CMF) measures the amount of money flowing in and out of a security based on the close position within the high-low range and the volume. When price closes in the upper half of the range with high volume, it represents accumulation (smart money buying). When price closes in the lower half with high volume, it represents distribution (smart money selling).
CMF is similar to OBV but more responsive to recent activity due to its period-based calculation. It's excellent for identifying divergences and confirming accumulation/distribution phases.
Formula
CMF combines money flow based on close position with volume over a specific period:
CMF ranges from -1 to +1. Positive CMF indicates accumulation (buying pressure), negative CMF indicates distribution (selling pressure). CMF close to zero suggests balanced supply/demand.
Parameters
| Parameter | Type | Default | Description |
|---|---|---|---|
| period | Number | 20 | The lookback period for calculating money flow. Standard is 20 periods. |
| source | Node | Auto | The data source node providing OHLCV data. Automatically detected from connected nodes. |
Popular Period Settings
| Period | Use Case | Characteristics |
|---|---|---|
| 10-14 | Short-term trading | Very responsive, many signals |
| 20 | General purpose (default) | Standard balance of responsiveness and stability |
| 30-50 | Swing/position trading | More reliable signals, fewer false reads |
Common Use Cases
1. Accumulation/Distribution Detection
Rising CMF indicates smart money accumulating. Falling CMF indicates smart money distributing. Use CMF to time entry/exit around institutional accumulation phases.
2. Divergence Trading
When price makes new highs but CMF fails to confirm (stays flat or falls), it signals weakness. These divergences often precede significant reversals.
3. Volume Quality Assessment
High CMF with high volume = strong institutional buying. Low CMF with high volume = strong institutional selling. Use CMF to gauge whether volume is in your favor.
4. Entry Confirmation
Confirm support bounces with rising CMF. Confirm resistance breaks with rising CMF as well. CMF near zero suggests weak entry signals.
Advantages & Limitations
Advantages
- •More responsive than OBV due to period-based calculation
- •Incorporates both close position and volume (holistic view)
- •Normalized -1 to +1 scale for easy interpretation
- •Excellent divergence detector
- •Works well in trending and ranging markets
Limitations
- •Can produce false signals in choppy markets
- •Less effective in low-volume sessions
- •Period selection affects sensitivity significantly
- •Requires price action confirmation for trading
- •Can stay at extremes during strong trends
Tips & Best Practices
💡 Combine with Moving Averages
Use moving average of CMF to smooth signals. A 5-period EMA of CMF reduces noise and provides clearer trend identification.
📊 Zero-Line Crossovers
CMF crossing above zero is bullish, crossing below zero is bearish. Use these crossovers as early warning signals of momentum shifts.
⚡ Filter with Support/Resistance
CMF signals are strongest at key support/resistance levels. A zero-line crossover at support is more reliable than in the middle of a trend.
⚠️ Avoid Trading Near Zero
When CMF is near zero line, it indicates indecision. Wait for a clear movement above or below zero before trading based on CMF signals.
Example Strategy: CMF Zero-Line Breakout
Using CMF zero-line crossovers for momentum trading:
CMF Breakout Long
Setup
- ✓ CMF has been negative (below zero line)
- ✓ CMF crosses above zero line with momentum
- ✓ Price below or at support level
Entry
- → Buy on the zero-line crossover bar
- → OR wait for pullback to rising CMF line for better entry
Stop Loss
- Below support level, or
- Below the swing low that CMF bounced from
Profit Targets
- 1st target: 1:1 risk-to-reward
- 2nd target: Resistance or CMF reaching +0.3 or higher
- Trail stop as trend continues
