What a Trading Plan Actually Contains: The Five Rules That Separate a System From a Hunch

Ask most retail traders if they have a trading plan and they'll say yes. Ask them to show it to you, and what usually comes out is a vague sense of what they like to trade and a rough idea of when they get nervous enough to sell. That's not a plan — it's a hunch with a brokerage account attached. A real trading plan is a written set of rules specific enough that two different days of your own judgment would still produce the same trade. There are five of them, and skipping any one is usually where the account starts leaking money.

Rule 1: An entry trigger you could hand to someone else

A real entry rule doesn't say "I like this setup." It says exactly what has to be true before you're allowed to click buy — a pullback to the 50-day moving average on rising volume, an IV rank above a specific threshold before you sell a vertical, a breakout that closes above resistance rather than just pokes through it intraday. The test is simple: could a coach or a fellow trader look at the same chart, apply your written rule, and arrive at the same decision you did? If the honest answer is "only if they knew what I was thinking," the rule isn't written yet — it's still a feeling.

Rule 2: Position sizing decided before you see the trade

Sizing has to be a formula, not a mood. Most disciplined traders risk a fixed percentage of account value per trade — often 1-2% — calculated from the distance between entry and stop, not from how confident the setup feels. The reason this rule exists isn't to cap your upside; it's to guarantee that no single trade, including the one you're most sure about, can do real damage to the account. The traders who blow up rarely do it on a string of normal losses. They do it on the one trade they sized bigger because it "couldn't lose," with no rule stopping them.

Rule 3: An invalidation level set at entry, not improvised later

Every position needs a predetermined point where the original thesis is wrong — a stop-loss on a swing trade, a defined max loss on a credit spread, an adjustment trigger on a covered call that's moved against you. The level gets set when you open the trade, while you're thinking clearly, not three days later while you're staring at a loss and negotiating with yourself. A mental stop that moves every time price gets close to it isn't a risk rule; it's a delay tactic, and it's how a manageable loss turns into an account-altering one.

Rule 4: An exit plan for when you're right, too

Plenty of plans cover what happens when a trade goes wrong and say nothing about what happens when it goes right. That's a gap, because giving back open profits is just as common a leak as blowing through a stop. Your plan needs a rule for taking profit — a fixed target, a trailing stop once a trade clears a certain level, a scale-out schedule on a swing position — decided in advance so you're not re-litigating the exit in real time while the position is moving and your judgment is at its least reliable.

Rule 5: A review process that turns results into data

The last rule is the one traders skip most often, and it's arguably the one that compounds the fastest: a standing process for reviewing every trade after it closes. Not just the P/L, but whether you actually followed rules 1 through 4 or improvised somewhere along the way. A trade journal that tracks entry criteria, size, stop, exit, and what you actually did versus what the plan said turns a string of trades into a dataset you can learn from. Without it, you're not building a system — you're just accumulating outcomes and hoping the good ones outweigh the bad.

A system you can test beats a feeling you can't

The difference between a hunch and a system isn't confidence — plenty of hunches feel completely certain right up until they don't. The difference is that a system is written down specifically enough to follow on your worst day, sized so no single trade can end the account, and reviewed often enough that it actually improves. None of that requires predicting the market correctly more often. It requires having five rules in place before you need them, not while you're in the middle of needing them.

If you're still building that structure, you don't have to do it alone — start your 15-day free trial with AJ Monte and work through your entry, sizing, and exit rules alongside a coach with 40+ years of floor experience instead of guessing at them in isolation.
