Most active traders don’t lose money because they’re bad at picking direction.

They lose because they don’t have a system — a written, repeatable process that tells them why they’re in a trade, how much they’re risking, when to add, and when to get out.

Without that foundation, every position becomes a fresh emotional decision, and the wins and losses average out to something painfully close to zero.

I spent the early part of my career on the floor of the Chicago Mercantile Exchange and later as a market maker at the Chicago Board Options Exchange. The traders who survived weren’t the ones with the best instincts. They were the ones with the tightest process. They were the best at managing money.

In today’s essay, I’m laying out a framework I’ve refined over more than two decades — six principles that, taken together, form the spine of a structured high-probability trading practice.

And while I’m laying out the principles that have guided my work for 28+ years, I don’t want you to miss out on the system I’ve built on them.

Last week, I laid out the exact system I’ve used for decades to discover opportunities in every corner of the options market.

My friend and colleague Marc Chaikin helped me develop something truly special. A system that analyzes more than 20 different factors—technical and fundamental—and turns all that noise into something simple: Bullish. Neutral. Bearish.

We call it the Convergence Trigger. And for a limited time, we’ve made a special replay of the full event available to anyone who’s interested. Just click here to learn all about the Convergence Trigger.

Now, let me show you the principles every good trader should follow…

1. Have a ‘Why’ for Every Trade

The best traders can articulate, in one or two sentences, why they’re in a position. If you can’t write down the reason before you click buy, you don’t have a trade — you have idea.

A defined reason isn’t “I think XYZ will trade higher.” It’s something testable: This refiner is the cheapest of its peer group relative to the crack spread which is trading at multi-month highs. Or: This stock is sitting at the bottom of its 30-day expected move and smart-money call buyers keep hitting the tape. The reason gives you something to fall back on. If the reason breaks — the crack spread turns, or the unusual flow reverses — you have a clear exit.

The simplest discipline I know is this: keep a one-line “thesis” field in your trade log for every position. If you can’t fill it in, don’t take the trade.

2. Manage Risk at the Portfolio Level, Not the Trade Level

This is the rule that most retail traders get backwards, particularly when trading options.

Conventional advice says: pick a stop loss for every trade. For stock that can work. For options it often doesn’t, because options gap, they decay, and a 50% intraday drawdown on a long premium position can reverse in an afternoon. If you set a stop based on a fixed dollar loss, you’ll be stopped out of trades that ultimately work.  

The alternative is to define your total acceptable risk across all open positions and size each trade so that, in aggregate, you stay inside your defined risk. If your maximum portfolio risk is $5,000, that’s the sum of what you can lose across every open position if they all went to zero. You then allocate that risk: maybe four bullish trades and two bearish trades as offsets, none of them larger than your per-trade cap.

The practical version, when buying options: decide what you’re comfortable losing on a trade before you enter, buy a few contracts that matches that figure, and accept that as your defined risk to expiration. If you want to risk $500, the undisciplined exposes $1000 and tries to ‘stop themselves out’.   Risk what you are willing to lose.

3. Choose the Right Vehicle to Express the View

Investors often miss a step. They form an opinion — “I’m bullish gold” — and immediately buy the underlying. But the underlying is rarely the most efficient expression of the view.

Every directional opinion can be expressed in several ways, each with different exposures to direction, volatility, and time:

• Long stock — pure delta exposure, no leverage, no time decay.
• Long calls — long delta, long volatility, short time (theta decay works against you).
• Short puts — long delta, short volatility, long time (decay works for you).
• Vertical call spread — long delta with capped upside and reduced volatility exposure, useful when premium is expensive.

If you’re bullish but volatility is elevated, buying calls means paying up for vol that might be extremely expensive. Selling puts or using a spread may give you the same directional payoff with better economics. If you’re bullish and volatility is cheap, long calls can be the better expression because you’re getting leverage and a long-vol position.

The discipline is to slow down between “I have a view” and “I click buy” long enough to ask: which structure gives me the cleanest risk/reward for this specific view in this specific environment?  Should you buy stock?  Buy an option?  There’s so many ways to express a similar view, but not all are created equal.

4. Use Market Context to Decide When to Add — and When to Pull Back

A trading system isn’t just a list of setups. It’s also a set of conditions that govern when you press and when you ease off. Two tools I use daily:

The VIX curve. The VIX itself measures 30-day implied volatility on the S&P 500, but the broader curve — 9-day, 30-day, 90-day, one-year — tells a richer story. When the front end spikes and then quickly reverts, that’s typically a healthy fear flush and a constructive backdrop. When longer-dated VIX is grinding higher and taking out prior highs, that’s a market that doesn’t want to rally, regardless of what the headlines say. In that regime, the rule in my own book is simple: stop adding long delta. Existing positions can run; new bullish exposure waits.

The expected move. For any liquid name, the options market prices an implied 30-day range — roughly one standard deviation up and down. For most large-cap stocks, price stays inside that band 70%–85% of the time. That makes the boundaries of the expected move useful reference points. A stock pushing against the top of its expected move on heavy call volume is often a place to take profits, not chase. A stock at the bottom of its expected move with bullish flow is often a more favorable entry than the same stock 5% higher.

Neither tool is a prediction. Both are filters that help you size up or down without having to forecast.

5. Trade Less and Hold Trades Longer

After working with thousands of traders, I’d summarize the two biggest mistakes in one sentence: everybody trades too often and everybody trades too big.

Overtrading is usually driven by boredom or by needing to “do something” after a loss. The fix is structural, not motivational: cap the number of open positions, cap the number of new entries per week, and require that each new trade meet your written criteria. If nothing meets the criteria, the correct action is to do nothing.

Trade less, hold positions longer.

Oversizing is usually driven by the desire to make a loss back quickly or by confusing conviction with edge. The fix is a hard rule that maximum trade size is a function of recent performance, not recent feelings. Which leads to the next piece.

6. Chart Your Own P&L and Let It Govern Your Risk

The single highest-leverage habit I picked up on the floor of the Chicago Mercantile Exchange (CME) was charting my own equity curve and treating it like any other instrument. When the curve was making new highs, I was allowed to add size. When the curve was pulling back, I cut size — sometimes dramatically — until it stabilized. The logic is simple: a drawdown in your P&L is information. It’s telling you that whatever you’re doing isn’t matching the current market, and the correct response is to take less risk, not more.

A practical version: track daily and weekly P&L in a spreadsheet or charting tool. Set a rule that if your equity curve breaks below its 20-day moving average, you reduce position sizing by half until it recovers. Set another rule that you can only increase size after a fresh equity-curve high. These are arbitrary numbers — pick what fits your style — but the principle is what matters: let the data, not your mood, set your exposure.

This applies even to traders who are learning. Before risking real capital, paper trade with a tiered goal: make $300 on paper for a week, then earn the right to try for $600. If you fail at the lower tier, you don’t get to the higher one. The point isn’t the dollars — it’s establishing, in advance, that size is a privilege you earn through demonstrated performance.

Putting It Together

A repeatable active trading system isn’t a magic indicator. It’s the combination of six disciplines: a defined reason for every trade, risk managed at the portfolio level, the right vehicle for each view, market context to govern exposure, structural defenses against overtrading and oversizing, and an equity curve that dictates your risk appetite.

None of these are exciting in isolation. Together they’re the difference between traders who are still in the game a decade in and traders who aren’t. The market doesn’t reward cleverness as reliably as it rewards process. Build the process first.

And if you’re interested in building that process from the ground up, the Convergence Trigger Summit is exactly what you’re looking for.

The Convergence Trigger is the product of two approaches that Marc Chaikin and I have spent years developing.

But only over the last several months had Marc and I started started comparing notes. And that’s when we discovered something huge: We’ve both spent our entire careers tracking the same thing—the smart money—just from completely different angles.

My work identifies where big, high-conviction positioning is showing up. Marc’s Money Flow confirms where institutional capital is actually flowing in the underlying stocks.

One signal measures conviction. The other confirms direction. Together, they form something neither of us had alone—a super signal that tips us off to the biggest directional bets in the options market before the crowd catches on.

All Advanced Notice members get access to Convergence Trigger  right now. Whether you’ve been with us from the beginning or just joined last night.
