The Elder Impulse System is a trend and momentum filter created to simplify chart reading into a small number of clear states. Instead of giving a single oscillator line, it combines trend direction and momentum direction, then shows whether bullish pressure, bearish pressure, or mixed conditions are present. Traders often use it to avoid taking long trades when momentum is weakening or short trades when momentum is improving.
In practice, the method is built around two components. The first is a moving average, usually the 13 period exponential moving average, which acts as the trend filter. The second is the MACD histogram, which acts as the momentum filter. When both are rising, the system marks bullish conditions. When both are falling, it marks bearish conditions. When they disagree, the market is treated as neutral or mixed.
That makes the indicator less about exact entry timing and more about context. It helps answer a basic question before a trade is taken: is the market impulse aligned with the direction of the position. Many traders use it alongside price structure, support and resistance, and other confirmation tools such as Force Index or Balance of Power. The Elder Ray Index, another tool by Alexander Elder, takes a different approach — instead of a state filter, it isolates Bull Power and Bear Power as separate oscillators to quantify the strength of each side.
How Elder Impulse System is calculated
The Elder Impulse System is not a single formula in the way a classic oscillator is. It is a decision rule based on the slope of an EMA and the slope of the MACD histogram. The indicator checks whether each component is higher or lower than its prior value, then assigns a state.
text{EMA}_t = alpha cdot P_t + (1-alpha)cdot text{EMA}_{t-1} alpha = frac{2}{n+1}In this setup, P_t is the current price, n is the EMA period, and alpha is the smoothing factor. The standard setting uses n=13. Traders focus less on the absolute EMA value and more on whether the EMA is rising or falling from one bar to the next.
The MACD histogram is derived from the difference between the MACD line and its signal line.
text{MACD} = text{EMA}_{12} - text{EMA}_{26} text{Signal} = text{EMA}_9(text{MACD}) text{Histogram} = text{MACD} - text{Signal}The impulse state can then be expressed as a simple rule.
text{Bullish if } Delta text{EMA}_{13} > 0 text{ and } Delta text{Histogram} > 0 text{Bearish if } Delta text{EMA}_{13} < 0 text{ and } Delta text{Histogram} < 0 text{Neutral if the two conditions disagree}The variables Delta text{EMA}_{13} and Delta text{Histogram} mean the current reading compared with the previous bar. The logic is simple by design. Trend and momentum must agree for the signal to be directional.
Best Elder Impulse System settings and periods
The standard Elder Impulse System settings are 13 for the EMA and the default MACD structure of 12 26 9. These settings are common because they balance responsiveness with enough smoothing to reduce random noise. On daily charts, they are widely used for swing trading and position trading. On weekly charts, they can help identify broader trend phases.
Some traders keep the MACD settings unchanged but adjust the EMA period. A shorter EMA makes the system react faster, which can help on lower timeframes, but it also increases signal flipping in choppy conditions. A longer EMA makes the trend filter steadier, which can improve selectivity, but it may delay some entries after sharp reversals.
The settings choice depends on the job the indicator is expected to do. If it is being used only as a high level filter, slower settings are often acceptable. If it is being used to support pullback entries or breakout continuation trades, traders may prefer slightly faster behavior. Even then, most keep the core structure intact because changing both the trend and momentum engine at the same time can make the system less consistent.
A useful comparison is with Trend Intensity Index and Laguerre RSI. Those tools can become more sensitive with shorter settings, but the tradeoff is the same here. More speed usually means more noise.
How Elder Impulse System looks on charts
On charts, the Elder Impulse System is usually shown as colored bars or a colored overlay. A bullish state appears when both the EMA slope and MACD histogram slope are rising. A bearish state appears when both are falling. Neutral states appear when one is rising and the other is falling. This presentation makes chart scanning easier because traders can see market condition shifts without reading several separate panels.
During strong uptrends, bullish readings often cluster in runs. Pullbacks may create a few neutral bars, then return to bullish once trend and momentum realign. In downtrends, the reverse is true. Bearish readings can appear in waves, while weak countertrend bounces often produce only short neutral interruptions before the bearish condition returns.
The most useful chart behavior is not the first color change by itself but the sequence around it. A single bullish bar after a long decline is not enough evidence on its own. Several aligned bars, especially when price also reclaims a moving average or breaks a swing level, are usually more meaningful. The system becomes more practical when it is read with structure rather than treated as a standalone trigger.
When Elder Impulse System works best
The Elder Impulse System tends to work best in directional markets with orderly momentum. These are markets where trends persist long enough for the EMA slope and MACD histogram slope to reinforce each other. In that environment, the indicator helps traders stay aligned with the prevailing move and avoid taking trades against the dominant impulse.
It is especially useful during pullback continuation setups. In an uptrend, price may retrace for a few bars while the system turns neutral. When both trend and momentum improve again, the bullish state returns and can confirm that the pullback may be ending. The same logic applies in downtrends after weak rallies. This is why many traders use the method as a filter for continuation entries instead of a reversal tool.
The system can also work well in breakout trading when the breakout is supported by expanding momentum. A breakout bar alone is not always enough. If the EMA is rising and the MACD histogram is also improving, the move has better internal support. That does not remove risk, but it helps filter weaker setups. For trend strength confirmation before using the Impulse System, ADX can help confirm whether the market is actually trending. A rising ADX above 20-25 paired with aligned impulse bars tends to produce better results than impulse signals alone.
When Elder Impulse System fails
The Elder Impulse System tends to fail most in sideways markets. When price rotates inside a range, the EMA slope changes often and the MACD histogram reacts to short bursts of movement that do not lead to trend follow through. This creates alternating bullish, bearish, and neutral readings that can tempt traders into overtrading. In those conditions, the Supertrend indicator may provide cleaner directional signals since it is purely price-driven and does not rely on momentum histogram slope.
It can also struggle during late trend phases. A trend may still be intact in price terms, but momentum may start to flatten. In that case, the system may shift to neutral earlier than some traders expect. That is not necessarily wrong, but it can lead to premature exits if the trader assumes every loss of alignment means reversal.
Another common trap is using the system on very low quality charts or thinly traded names. The indicator depends on the relationship between short-term trend and momentum. If the underlying bars are erratic, the output will be erratic as well. It usually performs better on liquid instruments and on timeframes where price movement is more meaningful.
Elder Impulse System trading rules and filters
A practical way to use the Elder Impulse System is to let price structure define the setup and let the indicator confirm it. For long trades, first require price to be above a rising medium term average or above a clear support zone. Then wait for a pullback, and look for the system to shift back to bullish as price resumes higher. This reduces the chance of buying into a fading move.
For short trades, flip the process. Require weak structure first, such as price below a falling average or below a broken support area. Then wait for a rally to lose strength and the system to turn bearish again. The indicator is doing its best work when it confirms renewed downside pressure inside an already weak market.
Stops are usually better placed from price structure than from the indicator itself. Common choices include below the pullback low in a long trade or above the rally high in a short trade. Some traders also use an ATR based stop to account for volatility. Exits can be handled by target levels, trailing structure, or by reducing exposure when the system turns neutral after a strong run. The MACD itself can add a finer-grained momentum perspective – checking histogram direction alongside the Impulse System’s binary state can help distinguish weak signals from strong ones.
A simple rule set many traders use looks like this:
- Trade long only when price trend is up and the system is bullish
- Trade short only when price trend is down and the system is bearish
- Ignore first signals inside obvious ranges or near major resistance and support without confirmation
Common mistakes with Elder Impulse System
Treating every color change as a trade signal is one of the most frequent errors. A single green bar after a long red run does not confirm a reversal. The system is designed to classify conditions, not to time entries. Wait for a sequence of aligned bars combined with price structure before acting.
Using the Impulse System without price context is another problem. The indicator tells you the current state, but it does not define support, resistance, or risk. A bullish impulse reading near major resistance is very different from the same reading at a clean breakout level. Always anchor to chart structure first.
Expecting the system to work in choppy ranges leads to frustration. When price rotates inside a tight range, the EMA slope and MACD histogram slope flip constantly. The resulting green-red-blue alternation is noise, not signal. If the market is clearly ranging, step aside regardless of what the color says.
Adjusting both EMA and MACD settings simultaneously makes it hard to understand which change improved or hurt results. Changing the EMA period shifts the trend component, and changing MACD parameters shifts the momentum component. Change one at a time and test over a meaningful sample.
Ignoring neutral bars means missing useful information. Neutral bars mean trend and momentum disagree. Many traders skip these bars and only watch for green or red, but the duration and context of neutral stretches can tell you whether a trend is pausing or genuinely shifting.
Elder Impulse System summary
The Elder Impulse System combines a trend filter and a momentum filter into one simple market state model. It checks whether the 13 period EMA and the MACD histogram are both rising or both falling, then labels conditions as bullish, bearish, or neutral. Its main value is not prediction. Its value is keeping trade decisions aligned with current impulse.
In practice, it tends to be most useful for filtering continuation trades, confirming breakouts, and avoiding positions taken against the prevailing move. It tends to be less reliable in choppy ranges, low quality markets, and late trend phases where momentum fades. For related perspectives, the Elder Ray Index isolates Bull and Bear Power as separate oscillators, ADX measures pure trend strength, and MACD provides finer-grained momentum detail. Traders who use the Impulse System with price structure, support and resistance, and disciplined risk rules usually get more value from it than traders who use every color change as a standalone signal.
