Capital Scaling: Growing and Protecting Through Multi-Year Cycles
Capital scaling — growing per-trade risk after demonstrated edge, scaling down after drawdowns — is mechanical at Stage 2, not emotional. The four-quarter scale-up rule and 5%/10%/15% drawdown ladder are the operational mechanisms. This page covers both, including the math behind each threshold.
Variance budget — 8-15% of account
Variance budget is the maximum drawdown you can absorb without breaking discipline. At Stage 2, this is 8-15% of account, with 10% as canonical. Below 8%, the budget is too tight — normal Stage 2 drawdowns will exceed it. Above 15%, the budget is too loose. Compute, don't feel.
Risk-of-ruin computation
At 1% per-trade risk and 50% win rate, risk of 8 consecutive losses (8% drawdown) is roughly 0.4%. At 2% per-trade risk, same drawdown reaches in 4 losses (16% account drawdown), with probability ~6%. The non-linearity is the entire reason 1% per-trade risk is the Stage 2 standard.
Four-quarter scale-up rule
Increase per-trade risk by 25% only after four consecutive quarterly reviews show: rolling 30-trade expectancy positive on at least 75% of active setups; account at all-time high or within 5%; no major regime change occurring; weekly review streak unbroken. Four quarters is roughly 12 months — slower than retail wants, but the timeline at which the data is robust enough.
5%/10%/15% drawdown ladder
At 5% drawdown: cut per-trade risk by 33%. At 10%: cut another 33% and pause new setup entries. At 15%: full pause, 14-day audit, written re-engagement plan required before resuming. Most retail responds to drawdown by sizing up to recover faster — the single most expensive habit in trading.
Why scaling down is harder than scaling up
Scaling up feels like reward; scaling down feels like punishment. Both are mechanical responses to data. The discipline of scaling down is what protects multi-year capital across the inevitable drawdowns. Students who never scale down typically blow up; those who scale down mechanically compound.
FAQs
Can I scale up faster than four quarters if my edge is obvious?
The four-quarter rule exists because edges are noisier than they appear. 'Obvious' edge in 1-2 quarters is often regime-specific. Four quarters spans typical regime changes.
What if my drawdown is from a single bad day rather than a streak?
Single bad day still counts. The drawdown ladder applies to cumulative drawdown from peak, not duration of drawdown. A 5% loss in one day triggers the same 33% risk reduction as a 5% loss over 10 days.
Should I scale down based on individual setup expectancy too?
Yes — Stage 2 setup retirement criteria handle this separately. Setup-level scaling and account-level scaling work in parallel.
How do I track variance budget?
Add to playbook front page: current variance budget %, current per-trade risk %, computed risk-of-ruin for 8 consecutive losses. Update at every weekly review.
Is 2% per-trade risk ever justified?
On highest-conviction setups with documented track record. Stage 2 ceiling is 2%. Stage 3+ may use conviction-tiered sizing within band. Above 2% is structurally Stage 4 quantitative work with proper risk modelling.
