Most blown accounts aren't a failure of analysis. The trader read the market correctly half the time but risked too much when they were wrong. Position sizing keeps you in the game long enough for your edge to play out, yet it is the thing most new traders give the least thought to.
ARIA recommends risking 0.5% of your account on every single trade, regardless of conviction level. That means on a $1,000 account, your maximum loss per trade is $5. On a $10,000 account, it's $50. This sounds conservative. That's the point.
"A 5R win is meaningless if a previous 10% risk loss wiped your motivation to keep trading. Stay in the game first."
| Account | Risk/Trade (0.5%) | TP1 Return (5R) | TP2 Return (7R) |
|---|---|---|---|
| $500 | $2.50 | $12.50 | $17.50 |
| $1,000 | $5.00 | $25.00 | $35.00 |
| $5,000 | $25.00 | $125.00 | $175.00 |
| $10,000 | $50.00 | $250.00 | $350.00 |
| $25,000 | $125.00 | $625.00 | $875.00 |
Even Phase A signals lose sometimes. A 70% win rate means 30% of trades are losses. If you size up on conviction and hit a loss streak, the damage compounds fast. At 0.5% risk, you can lose 10 consecutive trades and still have 95% of your account. At 5% risk, 10 losses leaves you with 60%. The math is brutal at high risk and kind at low risk.
Multiply your account balance by 0.005. That is your maximum risk in dollars. Then look at the SL distance in the ARIA signal in pips. Divide your risk amount by the pip value multiplied by those SL pips and you have your lot size.
