Risk Management
The mathematics that decides whether your account survives long enough for your edge to work. Position sizing, daily loss limits, drawdown mechanics, and risk of ruin — explained completely, without hype.
Why Most Funded Traders Fail
The most common reason funded account challenges fail is not a bad strategy. It is oversized positions during losing streaks. A trader with a winning edge can still blow a challenge by risking 2% per trade and hitting five consecutive losses — a statistically normal event that costs nearly 10% of the account.
Risk management for funded accounts is not the same as risk management for retail accounts. The consequences of breaching a daily or total drawdown limit are immediate and final: the challenge is failed, the fee is lost, and the process starts again.
The framework below is designed around one goal: keeping your account alive long enough for your strategy to work.
The Four Rules
Trade90 framework — internal discipline guidelines, not official prop firm rules
0.5% Maximum Risk Per Trade
Never risk more than 0.5% of your current account balance on any single trade idea. Use current equity, not starting balance — as drawdown accumulates, the dollar amount per trade shrinks automatically, which is correct behavior.
5 losses at 0.5% → −2.5% (safe)
5 losses at 1.0% → −4.9% (borderline)
5 losses at 2.0% → −9.6% (challenge at risk)
1% Personal Daily Risk Cap
Set your personal daily stop at 1% of account equity — well inside the typical prop firm daily limit of 4–5%. When total risk across all trades reaches 1%, stop trading for the day.
Trade 1: 0.5% risk → half budget used
Trade 2: 0.5% risk → budget spent
Result: stop trading, firm limit intact
Two Trades Per Day Maximum
At 0.5% per trade, two trades equals exactly the 1% daily cap. Two trades forces selectivity: you wait for the clearest setups, not the first opportunity. Over-trading is the second most common cause of funded account failures.
2 trades × 0.5% = 1.0% daily exposure
Firm limit: typically 4–5% daily
Your buffer: 3–4% intact
Check ADR Before Entry
Verify the Average Daily Range before every trade. If the instrument has already consumed most of its ADR before your setup triggers, the remaining range is thin and the trade carries elevated stop-hunt risk.
ADR mostly consumed → pass the trade
ADR mostly intact → full range available
Drawdown Survival — $100,000 Account
Account drawdown after consecutive losses at different risk levels, against standard prop firm limits. This is pure compounding math — it applies to every strategy and every firm.
| Risk / Trade | 5 Losses | 10 Losses | 15 Losses | Challenge Status |
|---|---|---|---|---|
| 0.5% | −2.5% | −4.9% | −7.1% | Safe — inside all limits |
| 1.0% | −4.9% | −9.6% | −14.0% | Borderline — near 10% max DD |
| 1.5% | −7.1% | −13.8% | −20.0% | Dangerous — exceeds max DD |
| 2.0% | −9.2% | −17.6% | −25.3% | Failed at 5 losses (most firms) |
Compound drawdown on rolling equity. Most prop firms use a 10% maximum total drawdown and a 4–5% daily loss limit. Model your own numbers with the drawdown calculator.
