Hands Off the Buy Button: Filtering Weak Setups and When to Sit Out · Lesson III
Market Conditions That Call for Smaller Size or No Trades
Knowing when to trade smaller size is a rule you write before the week starts. A hypothetical trader who normally risks $300 a trade cuts to $150 when the conditions below line up, and stops altogether when they stack.
In this lesson you will learn to
- Name the market and personal conditions that justify trading at reduced size
- Cut dollar risk per trade by a set fraction and recompute the share count from the stop
- Decide in advance when conditions stack up enough to take no new trades
Rate decision on Wednesday. The consumer price index on Thursday. Half your watchlist reporting earnings before Friday. The setups may look fine, and your pre-trade filter may clear several of them, but the week itself is loaded, and the distance between your stop and the price you actually get filled at is about to widen.
Some conditions call for smaller size. Some call for no trades at all.
The market’s conditions
Start with a choppy index. When the broad market reverses most days inside a range, individual stocks struggle to follow through. Breakouts fail, pullbacks keep going, and stops get hit more often than the setups deserve. See the column on whether to swing the range or stand aside.
Then come weeks with major scheduled releases. The Federal Reserve’s FOMC rate decisions and the monthly consumer price index report can move the whole market within minutes, and every open position moves with it, regardless of how good the individual chart looked. Crowded earnings weeks do the same thing stock by stock, and even a stock that isn’t reporting can gap on a competitor’s results.
Thin holiday sessions are the quieter hazard. Around market holidays, volume often drops, spreads can widen, and a modest order can move a price more than usual. The Loud News, Quiet Price quiz tests how headlines and price actually interact.
Your own conditions
The first is your drawdown. An account that is already down from its peak is the worst place to take full-size risk, because each further loss takes a larger percentage gain to recover and the pressure to win it back pushes toward bad trades. Set the threshold before you need it. The answer on how big a drawdown should make you stop trading looks at where to draw that line.
Then there is your state. Tired, ill, distracted, angry about the last loss, or trading to make back a bill: none of these show up on a chart. All of them show up in the results.
Half size in dollars
Take a hypothetical trader whose normal risk is $300 a trade. The rule: in any of the conditions above, risk half.
The stop stays where the chart says it goes. Only the share count changes, which the position size calculator works out for any risk and stop distance. Cutting the stop tighter to keep the old share count would defeat the point, since it raises the odds of getting stopped out in exactly the conditions where noise is worst.
A drawdown rule works the same way. Suppose the same trader’s account peaked at $30,000 and the rule is to halve risk once the balance falls 5% below that peak: 5% of $30,000 is $1,500, so the rule starts at $28,500 and stays in force until the account gets back above it.
Writing the rule down
A size rule invented on Wednesday afternoon is a mood. Write it on the weekend, when the coming week’s calendar is already public and nothing is at stake. It might read: “Risk $150 a trade in any week with a Federal Reserve rate decision or a CPI report, in any session next to a market holiday, and whenever the account is 5% or more below its peak.” Check the economic calendar and the earnings dates for your watchlist, mark the days that trigger the rule, and each day’s size is settled before the open.
Then track it.
Your journal should show which trades were taken at reduced size and why, so that after a few months you can see whether the smaller trades in those weeks lost less, as intended, or whether the rule mostly trimmed winners.
When to take no trades
One condition usually means half size. When they stack, the answer can be zero. A choppy index in a week with a rate decision, while your account sits in drawdown, leaves little for a good setup to work with, and the cost of sitting out is a few days without new positions. Write down which combinations mean zero. Do it before Monday.
The last lesson turns to the trades you skip, for these reasons or the filter’s, and how to grade those passes as if they were real trades.

C: 100 shares. Half of $400 is $200 of risk, and $200 / $2 a share = 100 shares.

B: An index reversing direction most days inside a range. A choppy index that keeps reversing breaks trends and follow-through on individual stocks, so stops get hit more often and smaller size limits the damage.
-
Show the answer
A: $38,000. 5% of $40,000 is $2,000, so the rule starts at 40,000 - 2,000 = $38,000.

Should you stop trading during Federal Reserve meeting weeks?
The rate decision and the press conference after it can move the whole market within minutes. A common approach is to hold fewer or smaller positions into the announcement and to avoid opening new trades in the hours just before it. Set your rule before the week starts, while the calendar is still only a calendar.
Is it better to trade half size or not trade at all in a bad market?
Half size keeps you in contact with the market and your process while limiting damage, which suits conditions that are merely difficult. Taking no trades suits conditions that stack up, such as a choppy index in a week of major releases while your account is already in drawdown. Write down which conditions lead to which response.
