Clicking buy or sell takes a second. Preparing to click well takes longer. The difference between a trade and a guess is usually not the chart; it is the handful of questions answered before the order goes in. A checklist will not make every trade a winner. It will keep small mistakes from becoming expensive ones, and it will expose ideas that sound good in your head but fall apart on paper. Here are eight questions worth running before you commit capital.
If you cannot state the thesis in one sentence, you are not ready to trade it. The sentence needs three parts: what you expect to happen, why it should happen, and over what rough timeframe. “The stock looks strong” is not a thesis. “A stock has broken above a three-month range on above-average volume, and I expect buyers to defend that breakout for the next few sessions” is something you can test.
Write it down before you look at position size. The act of writing forces you to separate a real idea from a vague feeling. It also gives you something to review later. If the reason for the trade changes, you can exit because the thesis changed, not because the price wiggled.
Ask what could make other traders care this week. It might be earnings, a product announcement, a sector move, or simply a technical level that many people watch. You do not need a dramatic story. You do need a reason the opportunity exists now rather than “sometime.”
This is where many good ideas turn into bad trades. Decide the risk before the entry, in money, not in confidence. A common approach is to risk a small, fixed percentage of your account per trade. The exact number depends on your situation, but the principle matters: one trade should not be able to damage your ability to take the next good setup.
Question 2: What is the maximum loss you accept on this trade? If the answer is “whatever it takes,” you do not have a risk plan.
Question 3: What position size makes that loss true? Suppose your account is $50,000 and you decide to risk 1%, or $500. You plan to buy at $20 with an invalidation level at $19.50. The distance is $0.50 per share, so the maximum size is 1,000 shares before commissions and slippage. If the stock gaps below your stop, the loss may be larger; size down if that possibility is real.
This calculation does two useful things. It keeps a strong opinion from becoming an oversized bet, and it shows when a stop is so wide that the trade is not worth taking at your risk limit.
Question 4: Where does the idea break? The invalidation level should come from the thesis, not from the amount of money you hope to make. If you are buying a breakout, a close back below the breakout level is a natural warning. If you are buying a pullback in an uptrend, a break below the swing low that defined the trend tells you something has changed.
Avoid stops placed at round numbers simply because they feel comfortable. Also avoid moving the stop farther away to avoid being wrong. The whole point of an invalidation level is to make the decision before your emotions have a vote.
Some trades are invalidated by events rather than price. A guidance cut, a failed regulatory decision, or a sudden change in a key input can kill the thesis even if your stop has not been hit. Write down those event risks too. If you cannot monitor them, reduce size or skip the trade.
Question 5: Is there enough liquidity for your order? Liquidity is not an abstract market term. It is the difference between getting filled near your intended price and paying a toll on the way in and out. Check the bid-ask spread, average volume, and the depth of the order book. A stock that trades thinly can look calm on a chart and become expensive when you need to sell.
For smaller accounts, liquidity is less of a problem in large caps and major ETFs. For larger orders, it matters everywhere. Compare your position size with typical daily volume. If you are trying to buy or sell a meaningful share of a day’s trading, use limit orders, work the order in pieces, and accept that the exit may take longer than the entry.
Decide whether you are using a market order, a limit order, or a stop order before the market moves. A stop order in a thin stock can fill far from the trigger. A limit order can leave you with no position if the move runs away. Neither is wrong by itself; the mistake is not choosing deliberately.
Question 6: If you are right, where do you take profit or trail your stop? A target is not a wish. It should connect to the thesis: a prior high, a measured move, a valuation range, or a level where the reward no longer justifies the risk. You can sell in pieces, trail a stop, or use a time-based exit. Pick one before the trade is live.
Question 7: If you are wrong or merely sideways, how long will you wait? Some trades need a few days to develop. Others are invalid if nothing happens within a session or two. A time stop is useful because it stops you from holding a dead position simply because it has not hit your price stop.
Also decide what you will do with event risk. If earnings are two days away and your plan is a short-term technical trade, holding through the report changes the deal. Either cut size, exit before the event, or accept that the trade is now a different trade.
Question 8: Does this trade still fit your portfolio and the current conditions? You can answer all seven earlier questions and still be about to make a bad decision. Maybe you already have too much exposure to the same sector. Maybe the market is in a risk-off mood and your setup depends on calm conditions. Maybe the trade is simply the fifth idea you have forced today.
Before you click, run the checklist once more:
If any answer is blank, the trade can wait. Missing a trade is cheap. Entering without a plan is not. This is general education, not personal financial advice; if your circumstances are complex, speak with a licensed adviser.
