Elder Impulse System Charting Styles

 THE ELDER IMPULSE CHART

Was designed by Alexander Elder and featured in his book, Come Into My Trading Room. According to Elder, "the system identifies inflection points where a trend speeds up or slows down". The Impulse System is based on two indicators, a 13-day exponential moving average and the MACD-Histogram. The moving average identifies the trend, while the MACD-Histogram measures momentum. As a result, the Impulse System combines trend following and momentum to identify tradable impulses. This unique indicator combination is color coded into the price bars for easy reference.

Calculation

Green Price Bar: (13-period EMA > previous 13-period EMA) and 
                 (MACD-Histogram > previous period's MACD-Histogram)

Red Price Bar: (13-period EMA < previous 13-period EMA) and 
               (MACD-Histogram < previous period's MACD-Histogram)

Price bars are colored blue when conditions for a Red Price Bar or 
Green Price Bar are not met. The MACD-Histogram is based on MACD(12,26,9). 

Green price bars show that the bulls are in control of both trend and momentum as both the 13-day EMA and MACD-Histogram are rising. A red price bar indicates that the bears have taken control because the 13-day EMA and MACD-Histogram are falling. A blue price bar indicates a split or equilibrium between buying and selling pressure.

Timeframe

The Elder Impulse System can be used across different timeframes, but trading should be in harmony with the bigger trend. Elder recommends setting your trading timeframe and then calling it intermediate. Multiply this intermediate timeframe by five to get your long-term timeframe. Traders using daily charts for an intermediate timeframe can simply move to weekly charts for a long-term timeframe. The choice is not as clear cut for smaller or longer timeframes. A little judgment is required. Traders using 10-minute charts chart their "intermediate" timeframe can use 60-minute charts for their "long-term" timeframe. Investors using weekly charts can base the bigger picture on monthly charts. Once the trading timeframe is decided, chartists can then use the longer timeframe to identify the bigger trend. This can even be accomplished using one chart. Chart 2 shows daily bars with the Elder Impulse System and the 65-day exponential moving average, which is five times the 13-day EMA. The long-term trend is considered up when SPY is above the 65 day EMA or when MACD (1,65,1) is positive.

Entries and Exits

A buy signal occurs when the long-term trend is deemed bullish and the Elder Impulse System turns bullish on the intermediate term trend. In other words, the weekly chart shows a clear uptrend and this means only buy signals are heeded on the daily chart. Sell signals are ignored. Elder suggests exiting when one of the two indicators turns down, either the 13-day EMA or the MACD-Histogram. Because the MACD-Histogram is based on a momentum oscillator, it is usually the first to turn down.

A sell signal occurs when the long-term trend is deemed bearish and the Elder Impulse System turns bearish on the intermediate term trend. For example, the weekly chart shows a clear downtrend and this means only sell signals are heeded on the daily chart. Buy signals are ignored. Elder suggests exiting when one of the two indicators turns up, either the 13-day EMA or the MACD-Histogram. Because the MACD-Histogram is based on a momentum oscillator, it is usually the first to turn up.

Conclusions

The Elder Impulse System is designed to catch relatively short price moves. Elder notes the following: "The Impulse System encourages you to enter cautiously but exit fast. This is the professional approach to trading, the total opposite of the amateur's style. Beginners jump into trades without thinking too much and take forever to get out, hoping and waiting for the market to turn their way."

In addition to trading setups, the Elder Impulse System can be used to prevent bad trades by consulting it before entering a trade. Use the Impulse System to confirm bullish or bearish setups. Traders can ignore bullish setups when the Impulse System is not in full blown bull mode (green bars) and ignore bearish signals when the system is not in full blown bear mode (red bars). The impulse system can also be used to anticipate patterns or reversals. If you think a bull flag is taking shape or support from a Fibonacci retracement is near, the Impulse System can be used to identify a short-term reversal for confirmation.

Using With SharpCharts

The Elder Impulse System can be accessed in SharpCharts by selecting "Elder's Impulse" for "Type" under "Chart Attributes". Overlays and indicators can be added to see just how the Elder Impulse System works or to determine the longer trend. For example, an exponential moving average can be added as a overlay or MACD can be added as an indicator. Click herefor a live example of the Elder Impulse System.

Further Study

The Elder Impulse system was first described in Elder's book "Come Into My Trading Room." It is also described in Elder's third book "Sell and Sell Short."
