Channel width and trend-filter lookback as separate swing-trading choices

Swing-trading as one procedure

Swing-trading, in this archive note, is a holding-period procedure that turns rule inputs, market state, and execution constraints into entry, exit, and abstention signals.

Those signals are located with a channel, a short simple-average band of highs and lows that sets swing entries, exits, and stop distance. A trend-filter is a longer lookback average that classifies directional regime before a swing signal is allowed. A moving-average is the defined-lookback smoother of ordered highs, lows, or closes used as that channel or as a trigger baseline.

Choosing the trigger bar

Some implementations of the swing-trading case used the current bar's five-period simple moving average of highs and lows as the entry and exit trigger rather than the previous bar's close against that band.

The author stated that last or current price may be used as the trigger, but that this choice produces more whipsaws if the move fails to follow through and is riskier than using the previous bar's close. A whipsaw is a quickly reversed signal when an intra-bar or last-price trigger fires without follow-through. The trigger-bar is the price print, prior close versus last or current price, compared with the channel to fire an entry or exit.

Even swings before systematic testing

Before systematic testing, the author required manual visual confirmation that an instrument produces relatively even, tradable swings and suggested inspecting five to ten years of history for that property.

Screens, portfolio-heat, and a large advance

A listed stock and ETF procedure filtered long candidates by strong relative strength versus major indexes and by industry groups outperforming a broad benchmark, and defined short candidates as the inverse of those two screens.

The same procedure treated a simultaneous account-risk cap of 5% or less as the primary constraint and called for scaling into a diversified mix of names and industry groups over time. Portfolio-heat is that share of account equity simultaneously exposed to open risk.

After a large broad-market advance, the notes called for much smaller position size, waiting for a pullback before new longs, or shifting attention toward shorts if the tape was topping.

The same skeleton on daily forex

A reader asked whether the same swing-trading method had been tried on forex, on the premise that liquid, trending markets were required for the procedure to function as designed.

The author's daily forex illustration used a 50-day exponential moving average as the trend-filter and replaced the five-day high/low simple moving-average channel with an eight-day version because large candle wicks appeared likely to force early stopouts.

The reply invited changing moving-average lengths independently for the channel and for the trend-filter on the markets actually under study, rather than treating those lookbacks as fixed.
