Instead of reacting to every headline, Defense sector investing can run on repeatable rules in Coinrule. Set triggers to scale in, take profits and cap drawdowns across your broker accounts. You stay in control while the platform executes your plan on schedule.
Traders often mix prime contractors, suppliers and broad ETFs to reduce single-name risk. The platform lets you automate a basket approach, then rebalance weights when one position runs ahead. Run the same logic across Charles Schwab, Trading212 and Tradier without rebuilding your workflow.
When volatility spikes, discipline matters more than conviction. Use position sizing, max allocation caps and time-based cool-downs so one move does not dominate your portfolio. Logs and alerts make it easy to review what happened and iterate without guesswork.
Sector Rules, Not Stories
Start with a template and change three fields: entry trigger, order size and exit rule. Example: buy 2% of cash if price drops 4% in 3 days, then set a 6% stop loss and a 10% take profit. Add a weekly schedule so checks run every Monday at 10:00.
Broker-Connected Automation
Connect accounts and keep execution consistent across names, ETFs and cash rules. Coinrule runs your logic the same way each time, so you can focus on research and portfolio construction.
Portfolio Rebalance
Rebalance a defense basket to target weights weekly. Trim positions above +8% and top up laggards below -5%. Add a max position cap to limit concentration.
DCA Accumulator
Split a monthly budget into four weekly buys. Increase buy size by 25% when price is down more than 3% week over week. Pause if drawdown exceeds 12%.
Buy the Dips
Buy after a 5% pullback from a 20-day high. Confirm with RSI below 40 on daily candles. Exit on a 9% rebound or a time stop after 20 days.
MA Crossover with Volume Filter
Enter when MA20 crosses above MA50 and volume is 20% above its 10-day average. Exit when MA20 crosses back below MA50. Add a 4% protective stop.
Volatility Breakout
Buy when price breaks above the prior 14-day high by 1%. Require ATR rising for 3 days to confirm momentum. Trail profits with a 3% trailing stop.

Buy when price breaks above the prior 14-day high by 1%. Require ATR rising for 3 days to confirm momentum. Trail profits with a 3% trailing stop.
Stop Loss and Trailing Take Profit
Set a fixed 5% stop loss on entry to limit downside. Switch to a 2.5% trailing take profit once the position is up 6%. Helps lock gains during fast runs.
Sector Momentum Switcher
Rotate into the strongest sector proxy based on 30-day performance. Move to cash if the proxy falls below its MA100. Recheck signals every Friday close.
Minimum Variance Rebalance
Target smoother equity curves by rebalancing toward lower-vol holdings. Reduce weight when 20-day volatility rises above a threshold. Rebalance monthly to avoid churn.
Risk-On/Risk-Off Macro Switch
Stay invested when a broad index is above MA200. Cut exposure by 50% if it stays below MA200 for 3 days. Re-enter after a recovery close back above MA200.
Earnings Drift Rider
Enter 1 day after earnings if price closes up more than 2%. Hold for 10 trading days unless a 4% stop is hit. Take profit early if price gains 7%.
Unlike one-off trades, a sector allocation benefits from rules that define when to add, when to trim and when to pause. Coinrule lets you set max exposure, such as 15% of portfolio value, and enforce it automatically. Schedule periodic rebalances so drift does not quietly change your risk profile.
For example, you might add on weakness only if the broader market is stable: buy when the stock is down 3% in 24 hours and SPY is above its MA200. Or require confirmation: enter only when RSI crosses above 50 after an oversold dip. These conditions keep your thesis measurable and reduce emotional overrides.
Once you set Defense sector investing rules, the system can check them on a schedule and act only when conditions match. That means fewer impulsive clicks and more consistent sizing. Run a conservative plan for long-term exposure and a separate tactical rule for short-term momentum.
Every action is logged with the trigger that fired, the order size and the timestamp. Alerts can notify you when a stop is hit or when allocation reaches a cap. Reviewing records helps you refine rules instead of relying on memory.

Rules work best when they are specific. Try a ladder: buy 1% at -3%, another 1% at -6%, then stop adding if drawdown hits -12%. Pair it with partial exits that sell 25% at +8% and another 25% at +12%.
Sector themes can drift into single-name bets. Set a max position size, such as 5% per stock, and a max sector cap, such as 20% total. If a holding rallies, the system can trim back to target automatically.
Not every approach needs constant monitoring. Many investors run daily or weekly checks to reduce churn and slippage. A weekly rebalance plus a daily risk stop is often enough.
Start with small order sizes and validate behavior across different market regimes. Confirm triggers fire as expected, stops are placed correctly and alerts reach you on time. Once the rule set behaves well, scale gradually and keep a change log.
Coinrule fits alongside your existing research tools and broker dashboards. Use it to standardize execution across accounts and reduce manual steps. If you expand into other themes, clone the same framework and swap tickers.
Pick a template, set your budget and define three numbers: entry threshold, stop level and rebalance frequency. You can be live in minutes, then iterate as you learn what works for your process. Keep it simple, measure results and refine.
