SDMAX - Stock Doctor 4/13-week High/Low Simple Moving Average crossover (weekly)


SDMAX was developed by Lincoln Indicators following extensive back-testing on Star Stocks over a 10 year period.

Stock Doctor’s 4/13-week High/Low Simple Moving Average crossover (weekly) indicator, identifies bullish and bearish trends to assist with entering and exiting the stock.


This strategy is suitable for investors who are very sensitive to price declines and are therefore willing to be very active tracking share price trends in the management of their portfolio which will experience increased stock churn. They wish to capture as much Star Stock performance as possible however, as the are more sensitive to price declines will cut losses earlier to avoid (potentially) greater loss.

This indicator displays the following moving averages:

  • Slow (13 week) simple moving average of the high and low price
  • Fast (4 week) simple moving average of the high and low price



How to apply:

Essentially, investors using this indicator, look for the bullish and bearish crossover points (both lines must cross each other) to determine when to enter and exit the stock.

The Entry trigger occurs when both fast moving averages cross above both slow moving averages. When the fast moving average of the low is above the slow moving average of the high, the stock price is considered Bullish (i.e. in an uptrend). This is indicated by a shaded (Green Bullish zone) on the chart.


The stock remains Bullish until the Sell trigger occurs, which is when both fast moving averages cross below both slow moving averages. When the fast moving average of the high crosses below the slow moving average of the low the stock price is considered Bearish (i.e. in a downtrend). This is indicated by a shaded (Bearish red zone) on the chart.


The use of a weekly time frame, means the indicator is not too sensitive and will still catch the majority of Star Stock performance.

  • Suits those who are highly sensitive to drawdowns in their stocks.
  • Cuts deep price losses (drawdown) sooner than the passive or SD30STR approach.
  • Gets into up-trending stocks sooner than the SD30TSR.
  • Weekly reviews mean investors are less prone to false signals.


  • Increased churn compared to other stop loss methods.
  • Be prepared for more losing trades.
  • If investors apply this strategy incorrectly i.e. do not back in, then it will cost them.
  • If the previous uptrend was very strong, it may take some time for the averages to revert which could become a big draw down.
