Orders and Execution

There are two basic ways to enter a trade. A market order says "buy (or sell) right now at whatever the current price is." It guarantees your order fills — but not the price. In calm, liquid markets the fill is close to what you saw. In fast markets, it can be shockingly worse. A limit order says "buy only at $50.00 or better" — it guarantees the price, but not the fill. If the market never touches your price, you simply do not get in.

The beginner's error is using market orders for everything out of impatience. You see a stock ripping upward, you smash the market-buy button, and you get filled at the top of a spike — seconds before it reverses. Professionals default to limit orders for entries: they decide the price in advance, place the order, and let the market come to them. If it never comes, that is information too — the trade was not actually available at your price.

The exception is exits in an emergency. If you must get out now — a stop triggered, news broke — a market order's guaranteed fill is worth the uncertain price. Speed matters more than precision when you are stopping the bleeding.

A stop order (usually a stop-loss) is an instruction that becomes a market order once price hits your chosen level: "if this stock falls to $48, sell everything." Its job is to take the decision out of your hands. You set it when you are calm and rational, so that future-panicking-you cannot negotiate.

This is the single most important execution habit in trading. Without a stop, every losing trade carries the theoretical risk of becoming catastrophic — and hope is not a risk-management strategy. The stop must be placed at a level where your trade idea is proven wrong (below support for a long trade, for example), not at a random distance that "feels" affordable. And once placed, moving a stop further away because you "just need more room" is the cardinal sin — it converts a planned small loss into an unplanned large one.

A close cousin is the stop-limit order: when triggered, it becomes a limit order instead of a market order. It protects your price — but in a violent gap or crash, it may not fill at all, leaving you in a plummeting position with no exit. For true protection, plain stop orders (market on trigger) are more reliable. You can also use stops to lock in gains: a trailing stop follows price upward at a set distance, so winners are protected while still having room to run.

Amateurs plan entries and improvise exits. Professionals plan both before risking a dollar. An exit plan has two parts: profit targets (where you will take gains) and the stop-loss (where you admit defeat). A common structure is taking partial profits — selling half at the first target to bank something, then letting the rest run with a trailing stop. This turns one trade into two outcomes and removes much of the emotional torture of "should I sell or hold."

Targets should come from the chart, not from wishes. Logical targets are prior resistance levels, measured moves from patterns, or round numbers where price often stalls. "I want to make $500 on this trade" is not a target — it is a hope with a dollar sign. The market does not know or care about your dollar goal.

And plan for being wrong quickly. The best trades tend to work fairly soon; a trade that goes nowhere for days is tying up capital and attention. Many professionals use a time stop: if the trade has not done what was expected within a set period, exit — even at a small loss or breakeven. Dead money is a quiet killer.

Slippage is the difference between the price you expected and the price you actually got. You click buy at $50.00 and fill at $50.15 — that fifteen cents is slippage. It is worst in fast markets, at the open, around news, and in illiquid stocks — exactly when beginners trade most aggressively. Slippage is a real cost: a strategy that looks profitable on paper can be unprofitable after slippage, especially for frequent traders.

A partial fill is when only part of your order executes — you wanted 1,000 shares and got 300. It happens with limit orders when there is not enough volume at your price. Beginners often do not notice, then discover they are holding a smaller position than planned (or worse, they cancel and chase with a market order). Always check your fills. If a partial fill leaves you with an awkward position size, either complete it deliberately or exit cleanly — do not let accident decide your risk.

Both frictions shrink with the same medicine from TF-102: trade liquid markets, avoid the chaos of the opening minutes unless that is your specific strategy, and never place market orders into thin, fast-moving books.

A bracket order bundles your entry with both exits in a single instruction: buy at this price, with a profit target above and a stop-loss below, all placed simultaneously. When one exit triggers, the other is automatically canceled (this is the OCO — one-cancels-the-other — logic). Many brokers let you set this up as a default so every trade enters the market fully planned.

Why bother? Because it removes the weakest link in execution: you, in the heat of the moment. The plan made by calm-morning-you executes exactly as designed, even when afternoon-you is tempted to move the stop or skip the target. It also protects you from yourself during distractions — a phone call, a meeting, a platform freeze — because the exits live on the broker's servers, not in your head.

Not every strategy fits brackets — some exits are discretionary — but every beginner should start with them. Until you have proven you can honor stops manually for months, automate the discipline.

Every platform goes down eventually — usually at the worst possible moment. The professional response is prepared in advance, not improvised in panic:

• Know your broker's phone number and keep it somewhere accessible. When the app freezes, the phone desk can close your positions.
• Never trade without a stop in the market. If the platform dies, your stop still lives on the broker's servers. A trader with stops survives outages; a trader without them watches helplessly.
• Have a backup device and connection. A phone with the broker's app and a mobile data connection has saved countless traders when the home internet dropped mid-trade.
• Do not double-order in a panic. If you are unsure whether an order went through, check your positions first. Panic-clicking "buy" three times during a freeze can leave you triple the size you intended when the system catches up.
• Keep position sizes sane. The ultimate outage protection is sizing so that even a worst-case gap cannot destroy you — which is exactly what TF-106 is about.

Execution is where trading plans meet reality, and reality has friction, delays, and outages. The traders who last are not the ones with the best ideas — they are the ones whose execution survives contact with the real world.

You can now get in and out cleanly. The final piece of the foundation is the math of survival: how much to risk, where the stop goes, and the daily limits that keep one bad day from becoming a bad career. TF-106 "Position Sizing and Risk" is the most important lesson in this school — the one that decides whether you survive long enough for any strategy to work.
