Capital Management
You can have the best strategy in the world, but if you don't manage your capital well, you'll end up bankrupt. Risk management is the only thing that guarantees your long-term survival.

1-2% Rule Per Trade
Never risk more than 1-2% of your capital on a single trade. With this, you can withstand 50 consecutive losses before losing everything. Example: $10,000 account → Maximum risk $100-200 per trade.
Kelly Criterion (Optimal Size)
Optimal position-fraction formula: Kelly% = WinRate − (1−WinRate)/PayoffRatio. It maximises long-term growth, but full Kelly is extremely volatile (50%+ drawdowns) — use ¼ or ½ Kelly. Try your own numbers in the interactive Kelly calculator above.
Position Pyramid (Scaling)
Add to winning positions (not losing ones). Scaling In: Enter with 50%, add 25% on confirmation, final 25%. Scaling Out: Take 50% at TP1, let 50% run with stop at breakeven.
Diversification
Don't have all your trades in the same asset or sector. Correlation: If BTC falls, many altcoins fall too (high correlation). Diversify among assets with low correlation.
Correlation: real diversification
Holding five positions is not diversifying if all five rise and fall together. Buying Apple, Microsoft, Nvidia, a Nasdaq ETF and bitcoin at once is, in practice, one leveraged bet on tech 'risk-on': when one falls, they all fall. Real diversification requires lowly or negatively correlated assets (stocks + bonds + gold, or sectors that don't move in unison). Before opening another position, ask: 'is this a new bet, or more of the same?'.
Sequence-of-returns risk
The ORDER in which your gains and losses arrive matters as much as their average, especially if you add or withdraw money. Two accounts with the same average return can end up very differently: the one that suffers a big losing streak early (when capital is already high, or just as you start withdrawing) may never recover, because a 50% drop needs a +100% to get back. That is why limiting drawdown early and not over-exposing at the start is not excessive caution: it is mathematical survival.
Minimum Recommended Ratios
There is no universal "minimum" R:R — it depends on your win rate. Break-even R = (1−WinRate)/WinRate: at 50% you need >1:1, at 40% you need >1:1.5, but at 65% accuracy you can be profitable below 1:1. Match the target R:R to your system's real hit rate, not to a fixed rule.
Calculation Before Entry
Measure every trade in R (1R = your risk from entry to stop). Place the stop where the idea is invalidated (structure or ATR), size the position so that distance equals a fixed % of capital, then read the reward as a multiple of R. Whether a given R:R is "enough" is decided by your win rate and expectancy — not by a 1:2 rule.
