Imagine the profile as a household and a trading engine trying to share the same oxygen. The simulator keeps asking a simple question:
how much pressure can that engine take before something important snaps—capital, runway, or behavior?
Household pressure: the monthly tug on cash
Monthly living costs, salary coverage, savings, and fixed tooling costs describe how hard real life pulls on the account every month.
High spending with little outside income means the trading program is constantly bled for withdrawals; low spending with good salary
coverage means trading can compound in relative peace. For example, with monthly living costs of 1,000 and 70% salary coverage,
trading is asked to carry about 300 per month; at 10% salary coverage, the same household asks trading for roughly 900 per month instead.
Adding 200 of monthly savings into reserves and 100 of fixed tooling costs means the model treats trading as facing a 500 per month cash
drain in the first case and 1,000 in the second. This pressure mainly feeds into ruin probability, behavior-driven stop risk,
and the cost-coverage score.
Capital and runway: how many bad months you can survive
Trading capital, reserve cash, and emergency funds form the cushion beneath the system. Together with the time horizon and your chosen
life mode, they determine how many bad regimes you can sit through before bills force desperate decisions. If you start with 50,000
of trading capital, 10,000 of dedicated reserves, and a 5,000 emergency fund, the model sees 65,000 of liquid cushion. With a full-time
burden of 3,000 per month and 6 months of “runwayMonths” before you lean on trading at all, you effectively prepay 18,000 of living costs,
so the first six months mostly test the edge rather than the household. A deep cushion and a longer runway lower ruin probability and
raise the odds of surviving the full horizon without forced shutdown.
Time, evidence, and process quality
Hours per week, live trading months, and the sliders for skill, operations, and discipline control how sharp and resilient the engine is.
More time and evidence, plus stronger process, make the effective edge more believable, reduce breakdown risk, and shrink behavior-driven
stop probability. As a concrete picture, a setup with 8 hours per week, 6 months of live trading, and skill/ops/discipline sliders around 4
is treated as quite fragile: the effective edge is heavily discounted and breakdown risk is high. The same capital run with 25 hours per week,
24 live months, and sliders near 8 is treated as much more robust, so a claimed 12% annual edge might be believed as roughly 10–11% instead
of being compressed toward zero. Thin experience and weak process do the opposite: they compress the edge, raise volatility, and make panicked
stops more likely.
Strategy style and structural edge
The strategy style choice and the annual edge and cost assumptions describe what the engine is trying to do before reality intervenes.
Different styles face different regime volatilities and breakdown patterns. A higher assumed edge or lower friction helps,
but only after being discounted by realism settings and process quality; aggressive claims under fragile process mostly inflate the left tail
instead of the dream outcome. For example, a “trend” profile with 20% expected annual net edge and 1% annual cost drag on 200,000 of deployed
capital has a notional 40,000 of pre-tax P&L before taxes and withdrawals. With weaker process or more fragile regimes, the model may only
credit 60–70% of that edge; with stronger process and a hopeful regime, it may credit most of it.
Realism and diversification
The assumption regime slider quietly leans everything hopeful, balanced, or conservative. It scales edge, cost drag, breakdown risk,
and stop penalties together. Diversification adds or removes independent sleeves of risk:
more genuinely distinct strategies smooth the distribution of ending wealth and improve coverage,
while a single concentrated sleeve leaves paths more at the mercy of bad regimes. As an illustration, a 15% edge under Balanced assumptions
is treated closer to 13% in the engine, while the same 15% under Conservative assumptions might be treated as ~11% and under Hopeful as
roughly the full 15%. Running two independent sleeves with that profile roughly halves the concentration risk relative to a single sleeve;
running four sleeves smooths outcomes further but asks more of process and tooling.
Mode choice: how much income you ask trading to carry
Life mode—side hustle, part-time, or full-time—decides how much of the household load trading is asked to shoulder.
The more you lean on it, the more aggressive the withdrawal policy becomes, especially in good months.
Side hustle runs mostly test whether the program deserves ongoing effort; full-time runs test whether constant cash extraction
and finite reserves leave enough room for the edge to show up before the left tail does. Numerically, if monthly living costs are 1,000,
side mode with 90% salary coverage asks trading for about 100 per month, part-time with 50% coverage asks for about 500 per month,
and full-time with 10% coverage asks for about 900 per month. The same trading engine therefore gets very different scores depending
on whether it is asked to fund 1,200 per year, 6,000 per year, or almost the full 11,000 per year.
Passive benchmark: the calm counterfactual
The benchmark panel compares that trading path with a low-cost ETF plan
funded by the same investable cash. It assumes monthly dollar-cost
averaging into a broad index ETF such as SPY, a modest fund drag, and a lower tax
burden on gains than short-term trading. That is the comparison the
feedback is asking for: not just whether trading survives, but whether
the extra work clears the quiet compounding alternative by enough to
justify the stress.
From assumptions to headline verdicts
In each run, the engine stochastically draws market regimes, trading shocks, and behavioral stress, then marches your capital and reserves
forward month by month. It tracks whether you survive the horizon, blow up, or effectively give up, and where your liquid wealth ends.
Those paths roll up into the five headline metrics: a viability score, cost coverage probability, ruin probability,
median ending wealth, and the chance that behavior—not just math—forces a stop. For example, a “careful builder” profile with 10,000
of capital, 1,000 of living costs, 90% salary coverage, 200 of monthly savings, and 14% edge under Balanced assumptions might show
a viability score in the 60s, cost coverage above 70%, and a median ending wealth of around 11–13k after three years. The same engine
run as a full-time attempt with 1,000 of living costs, only 10% salary coverage, no savings, and minimal runway might see its viability
drop into the 40s, with coverage closer to 25–30% and a much higher behavior-driven stop probability. Changing any input tilts this story
by changing how quickly pressure builds and how much slack the system has when it inevitably does.
