Manage Your Bankroll

Why bankroll comes first

The case for putting capital rules ahead of entry rules rests on one asymmetry that most traders know and few act on.

A loss removes a percentage of what you have, and the gain required to return to where you were is always larger than the loss that took you there. That gap widens sharply as the loss deepens, and it is the reason survival is a strategy rather than a caution.

Survival over profit

A trader with a mediocre method and firm capital rules stays in the game long enough to improve. A trader with a good method and no capital rules can be finished before the method has had a chance to show anything. This is not a moral point about discipline; it is that a rule set needs a number of trades to express whatever it is worth, and you have to still be trading when that number arrives.

Ruin-avoidance math

The arithmetic below is a worked illustration, not a result from any test. It shows the gain needed on the remaining balance to return to the starting point after a drawdown of a given depth.

Read the bottom rows carefully, because that is where the argument lives. A shallow drawdown is an inconvenience. A deep one is a different problem entirely, and the trader facing it usually responds by increasing stakes, which is exactly the behaviour that produced the depth.

There is a second reason capital rules come first, and it is about learning rather than arithmetic. A method can only be assessed across a stretch of trades, and every stake decision that varies adds a variable to that assessment. If your stake changed with your mood, a losing month tells you nothing about the rules, because the losses and the wins were not weighted equally. Fixing the stake is partly a protective measure and partly what makes your record readable at all, which is why it appears in the system pages as well as this one.

The compounding of losses

Sequence matters as well as size. A run of losses at a fixed fraction shrinks each subsequent stake automatically, which is one of the quiet virtues of fixed-fraction sizing: it decelerates as you decline. A run of losses at a fixed cash amount does not, and a run of losses with increasing stakes accelerates. Those three behaviours produce very different outcomes from the same sequence of trades, and the choice between them is made before the session rather than during it.

• Depth matters more than frequency. Many small losses are survivable; one large one may not be.
• Fixed fractions decelerate. The stake falls as the balance falls, without any decision from you.
• Recovery is asymmetric. Always larger than the loss that caused it.

Deep drawdowns need disproportionate gains to repair. Protecting depth is the whole job.

Set risk-per-trade limits

A per-trade limit turns an open-ended decision into a fixed one, and the fixing is where the value is.

The specific number matters far less than the fact that it is chosen in advance and does not move. Traders spend a great deal of effort optimising a figure they then abandon in the middle of a losing session, which is the wrong order of concern.

Small fixed percentage

Stake a small, constant fraction of the current balance on every contract. Small enough that a run of losses is uncomfortable rather than damaging; constant so that the decision is made once. Most traders who survive settle in the low single digits as a percentage, and the reason is not a formula: it is that a fraction of that size lets a long losing run pass without changing what you can do next.

Consistent sizing

The temptation to vary is strongest at the two moments when varying does most damage. After a loss, sizing up recovers faster if you are right and deepens the hole if you are not, and by construction you are less likely to be right in the state that produces the impulse. After a win, sizing up feels like pressing an advantage, and the advantage is usually a short run of good luck rather than a change in the method. Neither adjustment is supported by anything except how the last trade felt.

It is also worth planning for the good case, which almost nobody does. Decide in advance what happens when the balance grows: whether the stake fraction stays the same, whether anything is withdrawn at a threshold, and whether a larger balance changes anything about which setups you take. Traders without that plan tend to let a rising balance loosen everything at once, and a stretch of good results is followed by a stretch of bad rules. Writing the growth case down costs nothing and removes the moment where it gets decided by enthusiasm.

Avoiding all-in bets

A single large contract is not a strategy expressed loudly; it is a different activity. It has no relationship to your rule set, produces no information you can use, and the outcome is decided by variance rather than by anything you did. If you notice the urge, the useful question is what problem the trade is trying to solve, and the answer is almost always a previous loss.

One practical note: express the limit as a fraction of the current balance rather than of your original deposit. A fraction of the original amount stops decelerating as you decline, which removes the main protective property of the approach at exactly the moment you need it.

Choose a small fraction of the current balance, write it down, and do not revisit it inside a session.

Control drawdowns

A daily cap is the rule most likely to save an account and the rule most likely to be broken, and both facts have the same cause.

It binds hardest at the moment you most want to keep going, which is why it has to be numeric, set beforehand, and paired with a decision about what you do afterwards.

Daily loss caps

Pick an amount or a number of losing contracts that ends the session regardless of anything else. Set it low enough that reaching it is unpleasant and not damaging. The two failure modes are setting it so high that it never binds, which makes it decorative, and setting it so low that you hit it constantly and start ignoring it, which is worse because it teaches you that your limits are advisory.

Stepping away

What happens after the cap is reached is the part nobody plans, and it is where the damage occurs. An unplanned evening in front of the platform after a capped session is how a bounded loss becomes an unbounded one. Decide in advance: read the log, mark the rule breaks, close the platform. Having a scripted next action removes the moment where a decision would otherwise be made in the worst available state of mind.

A weekly view catches something the daily cap cannot. Three capped sessions in a row is not three separate bad days; it is a pattern, and the useful response is to stop and read the log rather than to arrive on the fourth day with the same rules. Whether the cause is the method, the market or your own drift, none of the three is fixed by another session, and all three are visible in a week of records read together.

Recovery discipline

The instinct to recover a loss quickly is the single most expensive instinct in this activity, and it is worth understanding why it is so persistent. A loss feels like a debt, and debts feel urgent. But the market has no memory of your balance, the next contract is unrelated to the last one, and nothing about the situation is more urgent than it was yesterday. The rule that works is that recovery happens at the same stake as everything else, over as many sessions as it takes, or it does not happen.

• Numeric cap, set before the session. Judgement-based limits fail exactly when needed.
• A scripted next action. Log, mark, close.
• No stake change after the cap. Same fraction tomorrow as today.
• Weekly cap as well as daily. Three capped days in a row is information, not bad luck.

A cap you honour plus a scripted next action. The second half is what makes the first half work.

Separate trading capital

Where the money comes from changes how you behave with it, reliably enough that it belongs in the rules rather than in a disclaimer.

Money you need does not permit the patience the method requires. That is the entire argument, and it is practical rather than moralising.

Only risk money

The amount you commit should be an amount whose complete loss changes nothing about your circumstances. The operator's own agreement makes a version of this point, recording that the client is aware they cannot invest funds "the loss of which will significantly impair the quality of his life". That is an unusually direct sentence for a document of that kind, and it is worth taking at face value.

Ring-fenced funds

Keep the trading balance separate from everything else, and decide in advance what happens to it. How much goes in, whether anything is added later, and under what conditions anything is taken out. A boundary that exists only in your head moves whenever the balance falls, and it moves in the direction of adding more, which is the mechanism behind most of the serious losses in this activity.

The same reasoning applies, more quietly, to money that is technically spare but emotionally committed. Funds you have mentally assigned to something specific behave like borrowed money even when nobody has to be repaid, because a loss carries a cost beyond the number. If you notice that a drawdown makes you think about what the money was for, that is a sign the amount is too large for comfortable rules, and reducing it will improve your trading more than any change to your entries.

No borrowed stakes

Trading with money that has to be repaid removes your ability to sit through a losing run, which is the one capability the whole approach depends on. It also changes what a normal drawdown means: a stretch that would otherwise be an ordinary part of the method becomes an emergency, and emergencies produce the stake increases that turn drawdowns into losses. There is no version of this that works, and it is worth saying plainly rather than gently.

The operator's agreement also records that the client assumes the risk of possible loss of invested funds as a result of trading operations, and that such risks are not subject to state insurance. Neither statement is unusual, and both are worth reading as a description of where responsibility sits rather than as boilerplate.

Spare money only, ring-fenced, with the top-up rule decided before the balance falls.

Bankroll takeaways

These rules do nothing for your analysis and they decide what your analysis is worth, which is why they come first.

Protect capital first

Everything else on this site describes how to select trades. This page describes how to remain in a position to keep selecting them. A method needs a run of trades to express anything, and capital rules are what guarantee the run happens. That is the whole case, and it does not depend on any claim about performance.

Small, consistent risk

A small fixed fraction of the current balance, unchanged after wins and after losses, is the entire sizing method most traders need. It decelerates automatically in a decline, it removes a decision at the moment you are least equipped to make one, and it makes your record comparable across trades because the stake is not a variable in it.

• Fraction of the current balance. Not of the original deposit.
• Same after a win, same after a loss. Both adjustments come from feeling.
• Daily and weekly caps. With a scripted action after each.
• Spare money, ring-fenced. With top-up rules set in advance.

If you take only one habit from this page, make it the written record of your three numbers: the stake fraction, the daily cap and the weekly cap. Keep them somewhere you will see before a session rather than somewhere you will consult afterwards. Numbers that live in a note you open once a month have already stopped being limits, and the difference between a limit and an intention is entirely a matter of when you read it.

Survival enables edge

No figure is published here for the correct risk per trade, the correct cap or the expected outcome of following any of it, because this desk has measured none of those things. What can be said without measurement is arithmetic: recovery from a drawdown always requires a larger gain than the loss that caused it, and the requirement grows faster than the loss does. Rules that keep drawdowns shallow are therefore doing more work than rules that improve entries, and they are also the easier of the two to implement. You can rehearse the limits on virtual funds and find out this week whether you can actually stop at a cap, which is the only part of this that is actually difficult.

Rules that keep drawdowns shallow do more for your account than rules that improve entries.
