Trend-gated oscillator entry and exit rules

Coded studies allowed oscillator trades only when a percentage-retracement trend state was aligned with the intended side. The crossing threshold, the trend gate, the chosen exit, and an explicit stay-flat rule were specified together as one procedure.

  • Coded studies combined oscillator signals with a prevailing-trend constraint so new trades were allowed only when the market was classified as aligned with that trend.
  • A trend change was defined as a 20 percent retracement from the extreme price of the current trend, and a trailing filter could withhold entries that would fire during the down state.
  • The unfiltered baseline bought on a close when the oscillator moved below 30 and sold when it moved above 70; a rising-oscillator-threshold variant required a cross up through 50 instead.
  • Lookback, reversal percentage, trend-filter, rising-oscillator, and close-on-reversal switches were independent, so subsets of the same rule-based-entry procedure could be tested.

A complete procedure, not a lone crossing

The relative-strength-index is a bounded oscillator computed from ordered up and down closes over a fixed lookback, used here as a forecast-style baseline whose crossings can be compared with gated variants.

Coded studies combined those oscillator signals with a prevailing-trend constraint so new trades were allowed only when the market was classified as aligned with that trend. Trend-following, in this workflow, is a directional state taken from a percentage advance or retracement of a recent extreme, used to permit, block, or liquidate oscillator trades.

Editorial reading: the oscillator becomes a complete, testable procedure only when a percentage-retracement trend state, a chosen crossing threshold, a reversal-or-overbought exit, and an explicit stay-flat rule are specified together. That package is a rule-based-entry design: a fully specified long-entry, exit, and abstention procedure whose inputs, market-state tests, and holding-period rules can be coded and backtested as one system.

Baseline crossings and the trend state

The unfiltered baseline was specified as buying on a close when the oscillator moved below 30 and selling when it moved above 70. At least one coded study was long-only with chart-level parameters for backtesting.

A trend change was defined as a 20 percent retracement from the extreme price of the current trend. Percentage-retracement is that flip: the state changes when price gives back a stated fraction of the move from the current extreme.

A trailing uptrend filter turned on after price rose more than 20 percent from a low, with the inverse rule for a downtrend, so entries that would fire during the down state could be withheld. An optional exit closed an open long when an identified uptrend reversed by a decline of 20 percent or more from the last uptrend peak.

Price falls from the low 52s to about 43 twice while the 20 percent reversal filter is in its down state, then climbs to the labeled 58.10 close after the filter flips back to an uptrend. Closes were read from the Wealth-Lab daily AXP candlesticks against the two-dollar grid; 58.10 is the platform print on the last bar.

The source paints the 20 percent reversal downtrend pink (stay flat) and the uptrend green. The upper pane is RSI(14) with dashed 50 and 70 lines; those oscillator values were not traced. Digitised closes are approximate except the final 58.10.

Universe screen and switchable entries

A second selection rule limited candidates to names with shorter average trend lengths, using a scan-oriented trend-length measure to build a list before portfolio testing. Trend-length is the measured duration of an identified trend, used as a universe screen before any entry signal is applied.

A second entry variant required the oscillator to cross up through 50 rather than 30. Coded studies treated that mid-range cross as a switchable alternative to the classic oversold cross. The rising-oscillator-threshold is that mid-range requirement rather than a deeply oversold cross.

One programmable specification exposed oscillator lookback, reversal percentage, trend-filter on or off, rising-oscillator on or off, and close-on-reversal on or off as independent parameters so subsets of the same procedure could be tested.

Two long-only encodings

A calendar-window variant marked an uptrend when close exceeded 1.2 times the 252-bar low and a downtrend when close fell below 0.8 times the 252-bar high. It bought only while that state was up and a 14-period oscillator crossed 50, and sold when the state ended or the oscillator crossed 70.

Another long-only encoding required both a longer-horizon and a shorter-horizon percentage-advance-from-low test, with defaults of 20 percent above a 250-bar low and 5 percent above a 20-bar low, plus an oscillator crossing up through 50. It exited when the longer-horizon uptrend failed or the oscillator crossed down through 70.
