The order ticket is the worst place to start thinking. By the time your cursor is over Buy, four things should already be settled: how much you're risking, where you're wrong, what the position costs to hold, and what could move violently in the next few hours. Leverage sharpens all four, because the size your broker will let you open is not the same as the size your account can survive.
What follows is a pre-trade routine for any leveraged position — CFDs, spread bets, futures, forex. It takes two minutes once it's habit, and it exists to prevent the two failures behind most damaged accounts: trades that are too large, and trades with no plan for being wrong.
Read it as a checklist, not a lecture. Nothing here predicts the market. Every item is something you can answer in a sentence before the order goes in — and if you can't answer it, that silence is your answer.
1. Let the stop decide the size, not the margin
Most people size a trade by asking how much the platform will let them control. That's backwards. Decide the loss first, then divide it by the distance to your stop.
The arithmetic, in plain terms
Say your account holds £10,000 and you're willing to lose 1% on the idea — £100. Your stop sits 50 pips away. £100 ÷ 50 pips = £2 per pip. That is your size. If the minimum lot on your platform is £5 per pip, you do not round up. You find a different instrument, you wait for a tighter stop, or you leave the trade alone.
Notice what never entered the calculation: the margin requirement. Margin tells you what the broker needs as collateral. It says nothing about what a losing trade costs you. A position can sit comfortably inside your margin and still be four times too big for your stop.
Why the margin figure misleads
Leverage of 30:1 on a £10,000 account implies you can control £300,000. It does not imply you should. The gap between permitted and prudent is where accounts die, and it widens every time a broker raises your tier or quietly trims a margin requirement on a calm Friday afternoon.
If your position size is set by the platform's limit rather than your stop, you're not managing risk — you're renting it.
2. Know what the loss looks like if the stop slips
Stops are instructions, not guarantees. On a gap, a flash move, or a thin Sunday open, your fill can be materially worse than the level you typed in. So size for the slippage case, not just the polite one.
A practical habit: assume your realised loss could be 1.5 times your planned loss on anything held through a scheduled event or an overnight session. If that number makes you wince, halve the position. It's a cheap adjustment now and an expensive one later.
3. Price the cost of holding
A leveraged position is a rental. Overnight financing, swap rates, dividend adjustments, weekend triple charges — each one is small per day and enormous per quarter. Before you enter, know which side of the carry you're on.
- Financing: what does it cost per night, and is it charged on notional value or on margin?
- Direction: are you paying or receiving? Some instruments pay you to hold one side, which changes the maths of the trade entirely.
- Horizon: if your target is two weeks away, does the carry eat a third of the expected move before you get there?
An intraday trade doesn't care about any of this. A three-month position cares about little else. Know which one you're in before you click.
4. Check the calendar for anything violent
You don't need to trade the news. You do need to know when it lands. Interest rate decisions, CPI prints, payrolls, elections, earnings, index rebalances, contract expiries — these are the moments spreads widen, liquidity thins, and stops get swept by machinery rather than opinion.
Two questions worth asking every time:
- Is there a scheduled release inside my expected holding period?
- If it surprises, does it help me or hurt me — and by how much?
If a single print could double your intended loss, either shrink the position or admit you're placing a bet, not taking a trade. Both are allowed. Confusing the two is not.
5. Add up what you already own
Ten small long positions across banks, insurers and a broad index fund is one large long position in financials. Correlation turns a diversified-looking book into a single leveraged bet, usually right before it matters.
Before adding, ask what the new position does to your net exposure. If it doubles a theme you already hold, size it as an addition to an existing risk, not as a fresh entry. The same stop distance means something very different when it's stacking on top of three others.
6. Make sure the stop sits somewhere the market respects
A stop is not a number you choose for comfort. It's a level where your idea is proven wrong. Round numbers, obvious swing highs and last week's lows are where everyone else's stops sit too — which makes them targets as much as levels.
Place it where the thesis breaks, then check separately that the distance is compatible with the size your account can carry. If it isn't, the trade is wrong, not the stop. Moving the stop closer to make the size work is how a plan becomes a wish.
7. Confirm the market can absorb your exit
You can only sell to someone who wants to buy. Check the spread before you enter, and check the depth: does the order book, or the instrument's typical volume, look thin?
Wide spreads, halted markets, illiquid small caps, and the first minutes after a gap are where "I'll just get out" turns expensive. If the spread alone is a meaningful fraction of your intended profit, you're starting the trade in a hole and paying for the privilege.
8. Decide the exit before the entry
Every position needs two levels and one sentence. The levels are where you're wrong and where you're paid. The sentence is why you get paid.
Will you take profit at a fixed target, trail behind a moving average, scale out in thirds, or exit on time? Any of those works. Improvising at 2pm on a red day does not. The exit is the part of the trade you can control; deciding it under pressure throws that away.
9. Leave margin headroom
Running at 90% margin used is a plan for forced liquidation on an ordinary bad afternoon. Volatility expands, margin requirements on volatile instruments rise without warning, and the broker's requirement is the only one in the room that can't be negotiated.
A workable rule: never let a new position push your margin usage past roughly a third of available equity, and keep enough free margin to survive a two-standard-deviation day without being closed out. Headroom is not idle capital. It's the difference between holding a position through noise and having the decision made for you.
10. Write down the invalidation in one sentence
Before clicking, finish this sentence: I'm wrong if ______.
Not "if it goes down". Something specific and observable — price closes above the prior high, the spread inverts, the data comes in above consensus, the trend structure breaks, the earnings guidance misses. If you can't finish the sentence, you don't have a thesis. You have a direction.
The two-minute version
Once it's habit, the whole routine collapses into a quick scan down the ticket:
- Stop level identified, position size derived from it.
- Slippage-adjusted worst case acceptable.
- Holding costs priced for the intended horizon.
- Calendar checked for scheduled turbulence.
- Net portfolio exposure understood.
- Stop placed at a technically meaningful level.
- Spread and liquidity acceptable.
- Exit plan set in advance.
- Free margin comfortable after entry.
- Invalidation written in one sentence.
Ten lines. Two minutes. The value isn't in ticking boxes — it's in noticing which box you can't tick today.
What this routine is actually protecting against
None of these checks require a forecast. They require arithmetic and a few seconds of honesty. That's the point. A pre-trade routine can't tell you whether a trade will work; it can only make sure that when one doesn't, you're still around to take the next one.
Two failure modes cause the overwhelming majority of leverage damage. The first is size: a position so large that a normal, expected loss becomes an account-level event. The second is the absence of a plan for being wrong, which turns a small loss into a held loss, and a held loss into a margin call.
Every item above attacks one of those two. That's the entire checklist.
Final thought
The order ticket should be the least interesting part of your process. If you're deciding anything at the moment of entry — size, stop, horizon, exit — you've already skipped the work and you're about to do it under the worst possible conditions: quickly, emotionally, and with money already committed.
Good trades feel boring at the point of execution. The thinking happened earlier, in a quieter room, with a calculator.
Do the checks. Then click, or don't.
