Swing Trading Rules: The Rule-Set Working Swing Traders Run

Every consistently profitable swing trader runs a rule-set. Not generic advice - a written, specific, broker-enforced where possible, set of rules that govern what counts as a valid trade, when to stop, and what to never do. The traders who blow up don't lack good setups; they lack a rule-set that survives a bad month. This lesson covers the canonical swing-trading rule-set: per-trade risk, position-count caps, weekly drawdownDrawdownPeak-to-trough decline in account equity. Resets only at new equity peaks. Recovery math is asymmetric.Read in glossary → caps, correlation caps, no-trade conditions, and mechanical exits. Each is justified, not just listed.

Why the rule-set matters more than the strategy

A swing-trading strategy with 55% win rate and 2:1 R/RReward-to-riskDistance to target ÷ distance to stop. Minimum workable setups are typically 2:1 or better.Read in glossary → has +0.65R expectancy per trade - looks like a smooth equity curve in expectation. In practice, the strategy produces:

• 5-trade losing streaks every 50-100 trades.
• Weeks down 4-6% from random sequencing.
• Drawdowns of 10-15% from peak in a typical year.
• The occasional gapGapA discontinuity on the chart - the open of one bar is meaningfully above or below the close of the prior bar.Read in glossary →-risk shock that wipes 2-3% in a single overnight.

The traders who blow up react emotionally to these - sizing up to "make it back," abandoning the rules, or quitting at the bottom. The rule-set is what converts the positive-expectancyExpectancyExpected R-multiple per trade: (WinRate × AvgWinR) − (LossRate × AvgLossR). Positive = edge. Negative = bleed.Read in glossary → strategy into actual realized profit.

The canonical swing-trading rule-set

Rule 1: Per-trade risk cap (0.5-1.0% of equity)

Pre-commit to the maximum dollar loss you're willing to take on any single trade.

• Beginners: 0.25-0.5% per trade.
• Experienced traders: 0.5-1.0% per trade.
• Above 1%: aggressive. Only justifiable for high-conviction systems with proven edge across hundreds of trades.

The math: position size is calculated backward from the structural stop.

Position size = (account × risk %) ÷ (entry price − stop price)

For a $25,000 account at 0.5% risk per trade and a $4 structural stop on a $200 stock:

• Risk per trade = $125
• Shares = $125 / $4 = ~31 shares

You don't pick the share count and then place a stop where it fits. You pick the stop based on structure (typically below the prior swing low or below a moving averageMoving averageThe average price over the last N bars. Used as dynamic support/resistance and trend filter. EMA weights recent data heavier.Read in glossary →) and let the position size fall out of the math.

This rule is violated more often than any other. Most beginners size first ("I'll buy 100 shares because that's a round number") then place the stop wherever it doesn't hurt too much. That's not risk management - that's hope.

Rule 2: Max concurrent positions (3-5)

Cap the number of open positions at one time. Standard for retail swing traders is 3-5.

Why this exists:

• Correlation. If you hold 8 large-cap tech names, you're effectively in one trade - a tech-sector trade. A bad day for tech blows out all 8 simultaneously.
• Capital efficiency. With 0.5% risk per trade and 5 open positions, you're risking 2.5% of equity at any moment. Adding more positions doesn't add edge - it adds correlation.
• Cognitive load. You can hold 3-5 positions in working memory and make good decisions. Past 5, you're guessing.

The cap is about correlation-adjusted exposure, not "diversification." Holding 10 stocks all in the same sector is one trade in 10 wrappers.

Rule 3: Weekly drawdown cap (3-5%)

If the account is down 3-5% on the week, stop opening new positions until next Monday. Existing positions continue to be managed by their pre-set stops and targets.

Implementation:

• Check Friday at close: is the account down 3%+ from last Friday's close?
• If yes, no new entries Monday-Wednesday of next week. Manage existing positions to plan.
• Resume new entries only after demonstrating the routine still functions (see Trading After a Big Loss for the protocol).

Why this rule exists: the worst trading happens during drawdowns, when emotional state is poor and the "make it back" urge is strongest. A weekly cap forces a pause and breaks the emotional loop.

Rule 4: Correlation cap (no two positions in the same primary driver)

No two open positions should share a primary directional driver. Practically:

• No two positions in the same sector (avoid two tech stocks, two banks, two energy plays simultaneously).
• No two positions in the same theme (don't hold AMD and NVDA at once - they trade as one).
• No two positions in the same earnings window (if earnings are in the next 5 days for two of your holdings, treat them as correlated).

The logic: real diversification means the positions move independently. Stocks in the same sector, same theme, or same earnings window don't.

Rule 5: No-trade conditions

Pre-committed conditions under which you do NOT open new positions, regardless of how good the setup looks:

• Earnings within 5 trading days for the candidate stock. The risk-reward is corrupted by binary news.
• FOMCFOMCThe Federal Reserve committee that sets US interest rate policy. Meets eight times a year; the rate decision and the chair's press conference routinely produce the largest intraday moves of the month in stocks, bonds, and the dollar.Read in glossary → announcement day or 1 day before. Macro uncertainty overrides individual-stock setups.
• CPICPIThe Consumer Price Index - monthly inflation reading. The single most market-moving non-Fed economic release. Released around the 10th-15th of each month at 8:30 a.m. ET; bonds, stocks, and rate futures often gap on the print.Read in glossary →/NFP release morning. The first 60 minutes of the session is too noisy to enter positions; wait for the dust to settle.
• You're emotionally activated (just had a bad week, fight at home, etc.). Decision-making is compromised.
• You broke a rule yesterday and haven't done the post-violation review. Forced cool-down.
• Account is at all-time high after a 2-week run. This isn't a rule everyone agrees with, but many pros run it: the trade after a peak is statistically lower-quality due to overconfidence and recency bias. A 24-48 hour cool-off prevents winner's-tiltTiltTrading from emotional reactivity rather than your rules - usually after a loss, a missed move, or a surprising win. Recognized by sudden size increases, breaking your stop, or revenge entries. Industry-wide accepted that the only fix is to stop trading until calm returns.Read in glossary → entries.

Rule 6: Mechanical exits via bracket orders

Every entry includes a bracket order at the same time: target price and stop price both pre-placed in the platform.

Why: the mid-trade brain is not the same brain that planned the trade. Pre-placed orders enforce the plan automatically. The trader who manually exits ("I'll take profit when it feels right") realizes 15-25% less RR-multipleThe dollar amount risked on a trade. Every outcome is measured in R: a 2R winner made twice the risked amount.Read in glossary → per trade than the trader who lets bracket orders fire.

The full mechanism is in Loss Aversion in Trading.

Rule 7: Stops only move in your favor

Once the stop is placed, it can move to break-even (after price runs in your favor) or to a higher level. It cannot move further away from entry, ever, under any reasoning.

The number of trades destroyed by stop-widening is enormous. The trader watches price approach the stop, finds reasons it should be "a bit lower," moves the stop, and watches the trade go through the new stop too. The original stop was at structural invalidation; the new stop is at "wherever I needed it to be for the trade to still be alive." The new stop has no edge.

Rule 8: Earnings discipline

Three options for any open position with earnings approaching:

1. Close the position before earnings. Default. Re-enter after if the post-earnings setup is clean.
2. Take partial profits and let the rest run on house money. Acceptable if the position is up significantly.
3. Hold full position with explicit thesis. Only if you have a real fundamental view and have sized the position accounting for gap risk (effectively 50% smaller than normal).

Holding through earnings without an explicit thesis is the #1 swing-trading account killer. It's a coinflip on a binary event with negative expected value for retail.

Rule 9: Daily journal, no exceptions

Every closed trade gets a journal entry. The minimum:

• Setup (which named pattern).
• Entry, stop, target, exit prices.
• R-multiple realized.
• A/B/C grade (textbook / acceptable / forced).
• Was the trade on the morning watchlist?
• Were rules followed?
• One-line lesson.

For trades where rules were broken, note specifically which rule and what triggered the violation. Free template at Trading Journal Template. The deeper habit is in The Journal System.

Rule 10: Weekly review

Every Friday or Saturday, 60-90 minutes of structured review:

• All trades for the week - wins and losses, R-multiples, setup grades.
• Adherence: did rules get followed? Where were they violated?
• Identify the week's biggest mistake and the week's biggest win.
• Plan next week's watchlist and any pending pre-set bracket orders.

The weekly review is what separates traders who improve year-over-year from those who repeat the same mistakes for a decade.

The rule-set as a system

Each rule by itself is good. Together they form a system that protects the strategy from the trader.

• Rule 1 (per-trade risk) caps any single trade.
• Rule 2 (position count) caps total simultaneous exposure.
• Rule 3 (weekly drawdown) caps weekly damage.
• Rule 4 (correlation) prevents fake diversification.
• Rule 5 (no-trade conditions) filters out predictably bad setups.
• Rules 6-7 (mechanical exits) preserve realized R per trade.
• Rule 8 (earnings) eliminates the #1 catastrophic-loss path.
• Rules 9-10 (journal + review) generate the data that lets you improve.

Remove any one and the system has a leak. Most blow-ups trace to a violated or missing rule from this list.

The single biggest mistake with rule-sets

Most beginners write the rule-set, then break it within the first month. The pattern:

1. Trader writes: "max 3 open positions."
2. Week 4: takes 3 setups Monday. Tuesday sees a 4th setup that "looks even better than the first 3."
3. Reasons: "rules are guidelines, this one is special."
4. Takes the 4th. Goes against. Now 4 losing positions instead of 3.
5. Rule-set is broken. Future violations come easier.

The fix: broker-side enforcement wherever possible, accountability where not. A platform-level position limit. A daily-loss limit at the broker. Bracket orders pre-placed. Make rule-following infrastructure rather than willpower.

Key takeaways

• The rule-set, not the strategy, decides who survives the inevitable drawdowns.
• Per-trade risk: 0.5-1% (beginners 0.25-0.5%). Position size from structural stop.
• Max concurrent positions: 3-5. More is correlation, not diversification.
• Weekly drawdown cap: 3-5%. Stop new entries when hit.
• Correlation cap: no two positions in the same sector / theme / earnings window.
• No-trade conditions: earnings windows, FOMC, CPI/NFP mornings, emotional state, post-rule-violation, post-streak peak.
• Mechanical exits via bracket orders. Stops only move in your favor.
• Earnings discipline: close before, take partial, or hold with explicit thesis. Never hold blindly.
• Journal every trade. Review every week. Without data, no improvement.
• The biggest failure: writing the rules, then breaking them. Use broker-side enforcement to remove willpower.
