A moving-average short pullback that is only in scope in a decline

The archive treats declining, advancing, and basing markets as separate environments. A short setup that waits for a bounce to a 35-session average is reserved for a confirmed decline, with NASDAQ trendlines marking when that procedure is in force.

  • Declining, advancing, and basing markets are framed as distinct environments that each need a dedicated procedure rather than one generic system.
  • The short setup needs a downtrend, 15 consecutive closes below the 35-session average, a pullback to within 1% of that average, and a break of the setup session low before the short is entered on the following open.
  • A break of an ascending NASDAQ trendline creates an uncertain interval. Short-side tools stay in force only after lower highs and lower lows allow a descending line to be drawn.
  • The short-pullback procedure is intended for declining markets and is not applied while the market is advancing or basing.

Separate procedures for separate markets

The archive frames declining, advancing, and basing markets as distinct environments. Each environment needs a dedicated procedure rather than one generic system.

The moving-average short setup below is the declining-market procedure. The archive concludes that this short-pullback procedure is intended for declining markets and should not be applied while the market is advancing or basing.

The moving-average short setup

In this archive usage, the moving average is a 35-session simple average of closes. It is the pullback reference for a short-side setup that requires prior closes below the average and a retracement back to within a stated band of it.

The moving-average short setup requires a downtrend, 15 consecutive closes below the 35-day average, a pullback to within 1% of that average, average daily volume above 200,000 shares, a price above $15, and a stochastic reading below 80.

Trigger, entry, and cover

A valid setup on one session triggers only if the next session trades below that session's low, with the short entered on the following open.

In this archive usage, mean reversion is that short-side procedure: it waits for a bounce toward a declining average, then enters only if price breaks the prior session low. The bounce is treated as a temporary retracement inside a downtrend rather than a new uptrend.

The backtest exit used for comparison held the short for three days and covered at the open. Discretionary covers mentioned include approaching support, declining volume, or a close below the lower Bollinger Band.

An IBM session that met the rules

The IBM illustration met the pullback rules on March 31, 2005 and triggered the next session when price broke the prior low.

MAS short results in the January–October 2002 NASDAQ decline

In the 2002 NASDAQ decline the moving-average short test averaged a 1.67 percent gain per trade, winners made 4.18 percent, and losers cost 2.77 percent. Over the same holding windows the NASDAQ itself averaged a loss. The bars are the Average Profit/Loss and Average OCEXCH Profit/Loss rows from the AIQ Expert Design Studio summary.

The software entered and covered at the open and held each short for three sessions. The run assumed all 83 signals were taken; the article treats the 145.47 percent annualized figure as a merit score, not a forecast.

Trendlines that keep the procedure in or out of scope

The first historical test window cited is the NASDAQ decline from January 18, 2002 to October 11, 2002, when the index moved from 2098 to 1108.

In this archive usage, a trendline is a line drawn across successive NASDAQ lows in an advance or highs in a decline. It is used as a regime switch that tells the trader when short-pullback tools are in or out of scope.

Trendline breaks on the NASDAQ are used to mark a change of condition. A break of an ascending line creates an uncertain interval. Only after lower highs and lower lows is a descending line drawn to keep short-side tools in force.
