Phidias Fundamental $100KBefore each trade
Phidias Fundamental $100KYour real capital is $3,000, not $100,000: no daily loss limit is stated, 20 end the account. Size every trade so a normal losing streak cannot reach that limit, and set a daily limit of your own.
The loss side
your edge: +0.13R · $19 a trade on averageThe firm states no daily limit: yours is the only one.
End of day: the floor rises with your best closing balance, so after a run of winning days it takes fewer.
Over a typical run of 242 trades at a 55% loss rate, a losing streak of 8 or more happens in 60% of runs and one of 11 or more in 14%. The account ends at 20 losses in a row.
| Losses in a row | All lose next | In a day | In 100 trades | In a typical run |
|---|---|---|---|---|
| 2 · Your stopends the day by your choice | 30% | 44% | 100% | 100% |
| 20 · Max drawdownthe account is lost | 1 in 155,864 | — | 1 in 4,213 | 1 in 1,545 |
“All lose next” is the chance that the coming trades are all losers. The other three columns are the chance that such a streak happens at least once: in a day of 3 trades, in 100 trades, and in a typical run of 242 trades (the simulation's median), the streak that ends accounts. All are exact, from your win rate.

What this does not model
Variable R (stops and targets that move) · partial exits · news gaps · slippage · correlated trades · the firm's discretion · taxes.
The same strategy copied onto several accounts shares one outcome: they pass or fail together, so the odds above do not improve. Trading opposite sides across accounts to push one through (“hedged passing”) is prohibited by the firms that state a rule on it, and this planner never suggests it.
These figures treat each account as its own attempt, the best case, with the chance of one attempt from the simulation above. Each account is bought once: resets are not counted. A monthly plan bills again each month: these figures count the first month of each account.
Every rule this planner applies is published for this account. Other rules (news trading, time limits, a minimum profit for a day to count, scaling) are not simulated: read the firm's own page.

Nine times in ten one of these 3 attempts passes: $273 for the first, then $64 each time, plus $149 after passing

The same trades, sized four ways. Half size when the floor gets close is the most common advice: it trades a little speed for fewer lost accounts. The best figure of each column is in accent.

The drawdown floor
end of dayIt follows your end-of-day best balance, $3,000 below it, and never stops rising.
Every new high raises the line for good: keep a fixed buffer and take profits off the table with payouts.
Rushing against your plan
the same win rate and reward| Measure | Your plan | Rushing |
|---|---|---|
| Risk per trade | 5.0% of the drawdown · $150 | 100% of the drawdown · $3,000 |
| Your limits | on | none |
| Reached | 59.0% | 8.2% |
| Daily limit hit | 0.0% | 0.0% |
| Account lost | 14.4% | 91.8% |
| Expected cost to get funded | $466 · 1.7 accounts bought per pass | $1,137 · about 1 pass in 12 accounts |
Rushing sizes each trade so an average day makes the first target in one session ($6,000 in 3 trades, capped here at your whole drawdown: one loss ends the account). This account needs 3 trading days anyway. Same win rate, same reward: only the size and the limits change.
Kelly and the risk of ruin
what the formulas sayKelly = win rate − loss rate ÷ reward = 0.45 − 0.55 ÷ 1.5 = 8.3% a trade, applied here to your real capital, the $3,000 drawdown. Full Kelly grows fastest with deep swings on the way; most traders use a quarter to a half of it. You are at 0.6 Kelly: above half, losing runs get long.
The chance a losing run eats the whole drawdown (20 losses of room) if you traded these numbers without end, on one account.
The real figure for this account: its daily limit and its targets included.
Risk of ruin ≈ e^(−r × U), where U is the losses of room (the drawdown ÷ the risk of one trade) and r solves p · e^(−r × reward) + q · e^(r) = 1 (p the win rate, q the loss rate). Kelly and ruin assume trades of the same size, one after another.

Each run trades your numbers under the account's rules: its daily loss limit, its max drawdown (static, trailing, end of day or locking at the starting balance as the firm states it), its targets, its minimum days and its consistency rule, and under your own limits.

Phidias risk questions, answered from its rules
How much should I risk per trade on Phidias' $100K account?
Risk a share of the $3,000 max drawdown, not of the $100K: that $3,000 is what the Phidias Fundamental $100K can lose before it ends, so it is your real capital. At 5% of it a trade risks $150 (0.15% of the account); 2.5% is $75 and 10% is $300. With a 45% win rate and rewards of 1.5R, 59% of 10,000 simulated runs reach the target and 14% lose the account. A calculation, not a promise.
How many losing trades in a row end the day or the account on Phidias' $100K account?
Phidias states no daily loss limit on this account, so only the max drawdown ends it: at 5% of the drawdown a trade ($150), 20 losses in a row reach the $3,000 max drawdown. End of day: the floor rises with your best closing balance, so after a run of winning days it takes fewer. Over a typical run of 242 trades at a 55% loss rate, a losing streak of 8 or more happens in 60% of runs and one of 11 or more in 14%; a streak of 20 has a 1 in 1,545 chance of happening in such a run.
Does Phidias have a time limit or a consistency rule on the $100K account?
Phidias states no time limit for the Phidias Fundamental $100K. There is no consistency rule. At least 3 trading days are required.
What does Phidias' $100K account cost to get funded, with retries?
The Phidias Fundamental $100K costs $273 (list price). A fee of $149 is paid once, after passing. At the opening plan (5% of the drawdown a trade, 45% wins, 1.5R), 59% of attempts reach the target: 1.7 accounts bought per pass. Counting each retry at $64 (retries at the $64 reset), the expected cost is $466, and $550 covers 3 attempts, enough to be funded nine times in ten. It is a monthly plan: it bills again each month, and these figures count the first month only.
