01 · Position Sizing
Small, Constant, Survivable
The first rule is unglamorous: risk a small, constant fractionof your balance per trade. Not a round number that "feels right," not more after a loss — a fixed slice, so that no single trade and no normal streak can end the account. Everything else in trading assumes you're still solvent tomorrow.
| Balance | ~1% per trade | ~2% per trade |
|---|---|---|
| Rp 500,000 | Rp 5,000 | Rp 10,000 |
| Rp 1,000,000 | Rp 10,000 | Rp 20,000 |
| Rp 5,000,000 | Rp 50,000 | Rp 100,000 |
Sizing beats prediction
A mediocre strategy with disciplined sizing outlives a great strategy with reckless sizing. Variance guarantees losing streaks; only small, constant stakes let you ride through them.

The Stop Loss That Saves Accounts
A daily stop loss ends the session after a defined loss — no exceptions, no "one more to get it back." It caps the worst day and, crucially, cuts the emotional spiral that turns a small loss into a blown account. Pair it with a profit target so you also stop winning before the market takes it back.
| Rule | Purpose |
|---|---|
| Daily stop loss | Hard ceiling on a bad day; kills the revenge spiral |
| Daily profit target | Locks a good day before it's given back |
| Fixed base stake | Removes 'size up to recover' decisions |
| Capped martingale | Bounds the worst-case streak |
03 · Martingale & Ruin
Where Recovery Systems Get Dangerous
Martingale (raise the stake after a loss so one win recovers the streak) is seductive and risky: the worst-case stake grows exponentially with depth. It can fit inside good money management — but only when it's shallow and capped, and always sitting inside a daily stop loss.
No sizing scheme removes risk from binary options — it only shapes it. Most traders lose money here. Keep martingale to a maximum of ~3 steps at 2–2.5×, never risk money you can't afford to lose, and test every configuration on demo. Koala S Pro is a tool, not financial advice or a profit guarantee.

Frequently Asked Questions
What is money management in trading?
The rules that govern how much you risk per trade and per day — position sizing, a daily stop loss and profit target, and how deep any martingale can go. It decides whether you survive long enough for a strategy to matter.
How much should I risk per trade?
A small, constant fraction of your balance — many disciplined traders keep single-trade risk to ~1–2%, and the worst-case martingale cycle well under ~5–10%. The exact number matters less than keeping it small and constant.
Why is a daily stop loss so important?
It caps the damage of a bad day and, just as importantly, stops the emotional spiral that turns one loss into ten. It's the single highest-impact rule in money management.
Does martingale break money management?
It can. Martingale front-loads risk into deep losing streaks, so the worst-case stake grows fast. Keep it shallow (max ~3 steps, 2–2.5×) and always inside a daily stop loss.
Can a bot enforce these rules?
Yes — that's one of the strongest reasons to use one. Koala S Pro applies a fixed base amount, capped martingale, and hard daily stop loss / stop profit exactly, with none of the human urge to override them.
