3/10 Oscillator — Momentum Divergence Indicator
What is the 3/10 Oscillator (Osc 3/10)?
The 3/10 Oscillator (shown as Osc 3/10 in the DCMM dashboard) is a momentum divergence indicator derived from the Detrended Price Oscillator (DPO) family. It measures the difference between two short-term moving averages — a 3-period and a 10-period — to quantify the rate of change in momentum and identify potential inflection points in price trend.
Calculation
Osc 3/10 = MA(3) - MA(10)
Where MA(3) is the 3-period moving average and MA(10) is the 10-period moving average of closing prices.
When the 3-period MA is above the 10-period MA, the oscillator is positive (momentum favoring upside). When below, the oscillator is negative (momentum favoring downside).
Interpreting Osc 3/10 in DCMM
The 3/10 Oscillator is used in DCMM as a momentum context indicator:
Positive Osc 3/10 in a Drawdown Setup
A stock showing a positive (or turning positive) 3/10 Oscillator while in a DD drawdown cycle is a strong confirmation signal. It suggests that short-term momentum is beginning to recover even as the stock is still in the statistical “drawdown zone” — this combination often precedes accelerated reversals.
Negative but Rising Osc 3/10
A negative oscillator that is trending toward zero (becoming less negative) during a drawdown indicates improving momentum. This is the “early recovery” signal — the selling pressure is diminishing even before the full reversal becomes apparent.
Deeply Negative Osc 3/10
A very negative oscillator combined with an extended DD cycle may indicate a momentum continuation rather than reversal. In this scenario, the mean-reversion setup may require more time to develop — consider reducing position size or waiting for the oscillator to begin recovering.
The 3/10 Oscillator and the Broader DCMM Framework
The 3/10 Oscillator originates from research into price detrending and was popularized by trading researchers including Linda Bradford Raschke, who found that the 3/10 combination captures short-term momentum cycles in institutional stocks with high consistency.
In the DCMM system, it is used alongside:
- RSI (14): Traditional momentum indicator; extreme readings (< 30) combined with positive Osc 3/10 momentum can signal strong reversals
- SMA200: Long-term trend context — stocks below SMA200 in strong drawdown require more caution
- SMA200 Diff%: Distance from the 200-period SMA as a mean-reversion distance measure
ATR (14) — Volatility Context
The Average True Range (ATR) with 14-period lookback is also shown in the dashboard and provides volatility calibration for stop-loss placement. When using the Osc 3/10 signal for entry timing, ATR confirms whether the current session’s range is consistent with the stock’s typical volatility profile.
Practical Use
- Check Osc 3/10 direction (is it becoming less negative?) for DD setups
- Combine with RSI (14) — RSI < 30 + improving Osc 3/10 = oversold momentum turning setup
- Use ATR (14) to set stop-loss distances in absolute terms (not just percentage-based)
- Cross-check SMA200 Diff% — stocks far below SMA200 may have stronger mean-reversion magnitude but also more downside uncertainty
