- Set criteria that must be met before size increases
- Increase size in steps small enough to reverse
- Explain why a bigger account changes execution
Before this lesson
Accounts fail on the way up more often than on the way down. A trader survives the learning period, finds something that works, starts making money — and then loses it in the months after scaling up, trading a size that changes how every decision feels. This last lesson is about doing that transition slowly enough to survive it.
Criteria before size
Size increases need conditions, decided when you are not in a position to benefit from bending them.
| Criterion | Threshold |
|---|---|
| Trades since the last increase | 100 minimum |
| Expectancy over those trades | Positive, and consistent with the longer record |
| Drawdown limits breached | None |
| Deviation rate | Under 5% |
| Time at the current level | At least a quarter |
| Risk of ruin at the new level | Recomputed, still under your threshold |
All six, not most of them. The deviation rate is the one people skip and the one that predicts the failure: a trader deviating 15% of the time at $5,000 will deviate more at $50,000, because every deviation now costs ten times as much and the pressure that produces them is correspondingly larger.
Note
Note what is absent from that table: how much money you made. A profitable quarter is not a criterion, because a profitable quarter is entirely achievable with a broken process and some luck. The criteria are about evidence and execution, which is what actually has to scale.
Step sizes you can reverse
Increase the risk percentage in steps small enough that a bad outcome at the new level is recoverable, and that you can tell whether the problem was the size.
- 25% relative steps. 1% to 1.25%, then 1.5%, then 1.75%. Not 1% to 2%.
- One step at a time, held for the full 100 trades before the next.
- Step back immediately if the deviation rate rises or a drawdown limit is breached at the new level. Going back down is a normal event, not a failure.
- Stop somewhere. Most retail plans do not need to go past 2%, and Track 5's risk-of-ruin arithmetic is why.
The other half of scaling happens on its own and needs no decision. Sizing from a fixed percentage of a growing balance compounds, and for most traders that is the entire growth mechanism — the percentage never has to change at all.
| $10,000 at | After | Becomes |
|---|---|---|
| 3% a month | 24 months | $20,328 — a doubling with no change in risk percent |
| 2% a month | 36 months | $20,399 |
Try it now
The compounding calculator makes the case for patience better than any argument here: put in a monthly return you believe you can sustain and look at the balance three years out.
What changes at larger size
The arithmetic scales perfectly. Nothing else does, and the things that do not are what cause the failures.
| $5,000 account | $50,000 account | |
|---|---|---|
| 1% risk | $50 | $500 |
| A normal losing day | $150 | $1,500 |
| A 10% drawdown | $500 | $5,000 |
| What that feels like | A bad week | A month's salary |
- Every loss is now a recognisable amount of money, which is the actual difficulty. A $1,500 day is arithmetically identical to a $150 day and is not psychologically identical to anyone.
- Hesitation appears. Trades get skipped, which lowers the trade count and therefore the expectancy per month — Track 5's frequency lever, running backwards.
- Exits get early. Loss aversion scales with the size of the number, so the planned-versus-realised R gap widens at exactly the moment it costs most.
- Execution quality can genuinely change, at size. Track 2's broker lesson applies: larger orders may be routed differently, and slippage that was noise becomes a cost.
Caution
Watch the trade count in the first month at a new size. A sharp drop is the clearest early signal that the size is uncomfortable, and it appears before the results deteriorate — which makes it the most useful thing to monitor during a scale-up.
Withdrawing, and why it matters
Take money out regularly. This is not primarily a financial recommendation; it changes the nature of the activity.
- It makes the profit real. A number on a platform is a score. Money in your bank account is a result, and the difference matters for whether you keep doing this.
- It caps the exposure. Money withdrawn cannot be lost in a bad month, and a strategy that never withdraws puts every gain permanently back at risk.
- It tests the process. Track 2's lesson 6 made withdrawal a broker test; doing it regularly means you find out early rather than when it matters.
- It changes the psychology of a drawdown. A year that produced withdrawn income is a year that worked, even if it ends in a drawdown — and that is the framing that keeps a working trader trading.
A workable rule
- Withdraw a fixed share of profit — a third to a half — monthly or quarterly.
- Leave the rest to compound, which is the growth mechanism from earlier in this lesson.
- Never withdraw during a drawdown. Withdraw from profit, not from capital.
- Withdraw on a schedule, not on a feeling. A withdrawal decided after a good week is a different decision from one on a calendar.
That closes the core curriculum, and it is worth naming what has been repeated in every track: the decision is made when you are calm, written down, and executed when you are not. Position sizing, stop placement, drawdown limits, abandon criteria, scaling steps, withdrawals — every one of them is the same device applied to a different moment. Nothing in these eight tracks is more important than that, and almost nothing else has to be memorised.
Key takeaways
- Require all six criteria before a size increase — 100 trades, positive expectancy, no breached limits, deviation under 5%, a quarter at the level, and a recomputed risk of ruin.
- Step by about 25% at a time and step back without ceremony; a fixed percent on a growing balance compounds on its own.
- The arithmetic scales and the psychology does not — watch the trade count in the first month at a new size.
- Withdraw a fixed share of profit on a schedule. It caps exposure, tests the broker, and makes a drawdown survivable.
