Bull, Sideways and Bear Markets: Rule-Based Trading Guide
Markets alternate between rising, falling and going nowhere, and each regime punishes a different mistake. This guide explains how to tell the three apart and why the label only becomes clear afterward, how traders typically lose in each, what rule-based strategies do differently, what we observed in our own backtests, and the limits you should weigh.
Telling the three regimes apart
Working definitions:
| Regime | Price structure | Typical signs |
|---|---|---|
| Bull | Higher highs and higher lows | Price mostly above a rising longer-term average; dips get bought |
| Sideways | Overlapping swings inside a range | Flat average; breakouts fail and snap back |
| Bear | Lower highs and lower lows | Price mostly below a falling average; rallies get sold |
The catch is timing. These labels are clearest in hindsight. On a live chart, the first leg of a new uptrend looks like one more bounce in a bear market, and a range looks like a pause before the next trend. Any tool that classifies regimes relies on past bars, so it lags: by the time it says "bull," part of the move is already gone.
The practical conclusion is that a strategy shouldn't depend on knowing the regime in advance. It needs rules that behave acceptably in all three, and a position size you can hold through the regime it handles worst.
How traders typically lose money in each regime
| Regime | Typical mistake | What it costs |
|---|---|---|
| Bull | Chasing big green candles, often with leverage; shorting because "it's too high" | Buying near tops, then getting shaken out on the first pullback |
| Sideways | Treating every breakout as a new trend; overtrading | A string of small stop-outs, plus fees |
| Bear | Holding losers, averaging down, buying every bounce | Losses that grow until they feel too big to close; liquidation with leverage |
The common thread is decisions made in the moment and driven by the last few candles. The regime changes, but the trader's reaction doesn't.
What rule-based strategies do differently
Rules can't predict the regime, but they can respond to it consistently:
- Trend confirmation before entry. The rules wait for the market to show a direction through structure, momentum or volume instead of guessing the bottom. The cost: entries come later, and the first part of a move is usually missed.
- Exits defined before entry. Every position has an exit rule, so a loss stays a planned loss instead of becoming a position you "hold until it comes back."
- Standing aside or shorting in declines. Spot rules can simply stay out of the market during downtrends. Futures rules can short, so a falling market is also tradable, with the extra risks that leverage brings.
- Fixed position size. No doubling up after losses, and no oversized bets after wins.
- Consistency. The same conditions get the same response, which makes the approach testable; see how to read a backtest.
The trade-off is real: rule-based trend strategies get whipsawed in ranges and react late at turning points. That is the price of not guessing. Pullwave's strategy is a pullback approach of this kind, built on price and volume rules; pullback trading explained shows how it enters, adds and exits.
What we saw in our backtests, regime by regime
Here is what our own tests showed, described qualitatively:
- Bear markets. In our backtests, the spot approach mostly got out during steep declines, so its losses were much smaller than simply holding. The futures approach, which can short, was profitable in many declining stretches. It didn't happen every time: some declines still produced large losses.
- Bull markets. In our backtests, the strategy tracked a large part of sustained uptrends, though not the entire move. Short, sharp rallies were sometimes missed.
- Sideways markets. In our backtests, most sideways stretches passed without large losses, and profitable stretches slightly outnumbered losing ones. That is not the same as never losing: in choppy, saw-tooth markets, small losses sometimes came several in a row.
| Regime | What we observed (qualitative) | Where it fell short |
|---|---|---|
| Bear | Spot mostly stepped aside; futures profitable in many declines by shorting | Some declines still brought large losses |
| Bull | Tracked a large part of sustained uptrends | Short spikes sometimes missed |
| Sideways | Mostly no large losses; slightly more profitable stretches than losing ones | Runs of small losses in choppy ranges |
Keep two things in mind when reading this. First, these are in-sample results: the settings were refined on the same past data, so future results could be worse. Second, the regimes were labeled after the fact; the strategy never knew in real time which market it was in, and neither will you. Every backtest and every trade is on the performance page, so you can check the stretches yourself, and the SOL futures indicator overview shows how the same rules appear on a live chart.
Limits and risks to weigh
- No regime foresight. Rules respond to the market; they don't know what comes next.
- Futures drawdowns can exceed the allocation. In our SOL futures backtest, the maximum peak-to-trough drawdown exceeded 100% of the allocated amount, and the backtest doesn't model liquidation or margin. Keep the allocated amount well below your balance and start small; see max drawdown explained.
- Rules only help if you stick to them. Skipping signals after a losing streak, or doubling size after a win, turns a tested system into an untested one.
- Execution differs from the test. Slippage, fees, funding and the delay between an alert and your own order all shift results.
- Choppy ranges are where trend rules get whipsawed most. Size for a run of small losses, not for the good stretches.
FAQ
Q. How can I tell if the market is sideways right now?
Look for a flat longer-term average, overlapping candles, and breakouts that fail and fall back into the range. Treat any label as provisional, because a range can turn into a trend without warning and the label only becomes clear afterward.
Q. Which market regime suits a pullback strategy best?
Sustained trends: up for long positions, and down for short positions in futures. Choppy sideways markets tend to be the most difficult, because trends start and fail repeatedly.
Q. Should I switch strategies when the regime changes?
Because regimes are only recognized with a delay, a switch usually comes after the change has already hurt. A steadier approach is one set of rules designed to behave acceptably in all three regimes, with position sizes small enough to get through the worst one.
Q. Do rule-based strategies avoid losses in bear markets?
No. They can reduce exposure or trade the short side, but losses still happen. In our backtests, some declining stretches still produced large losses.
