Capital Preservation Checklist

Capital Preservation Checklist: Capital preservation is the first job of a trader, because survival is what allows any edge to compound. The non-negotiables: risk only a small fraction of capital per trade, honour every stop, cap total portfolio heat, set drawdown limits that force you to slow down, avoid the leverage and concentration that cause ruin, and protect against the tail that stops and VaR ignore. Keep drawdowns shallow, because deep ones are punishing to recover. This is educational discipline, not a signal.

Every other skill in trading is worthless if the account does not survive. Capital preservation is the discipline of never taking a loss large enough to end the game, so that whatever edge you have gets the time it needs to work. The habits below are deliberately few and strict, because in a crisis you fall back on rules, not intentions. The mathematics is unforgiving: a 50% loss needs a 100% gain to recover, so avoiding deep drawdowns matters more than any single win. See the Risk Management Cheat Sheet for the underlying tables.

Non-negotiable per-trade habits

• Risk only a small, fixed fraction of capital per trade; 1 to 2% is a common heuristic and many professionals sit lower.
• Define the rupee loss before entry and never place a trade whose risk you have not measured.
• Honour every stop without exception; never widen a stop to avoid taking a loss.
• Never average down on a loser outside a pre-planned, pre-sized rule.
• Size undefined-risk positions (naked options, futures) on a realistic adverse move plus a gap buffer, not on margin.
• Keep single positions small enough that an overnight gap past the stop is survivable, not catastrophic.
• Never risk money you cannot afford to lose, and keep trading capital separate from essential savings.

Account-level guardrails

• Cap total portfolio heat so a cluster of correlated stops cannot cause a severe drawdown; near 6% of equity is a common heuristic.
• Set a daily and monthly maximum loss limit that, once hit, stops trading until you review.
• Reduce position size when in drawdown, which both protects capital and shrinks the recovery required.
• Keep leverage modest; margin magnifies losses as readily as gains and is a leading cause of ruin.
• Maintain a cash buffer so mark-to-market swings never force distress selling or a margin call.
• Avoid concentration in one instrument, sector or factor that a single event could hit all at once.
• Trade well below the mathematically optimal Kelly size, since a full-Kelly bet produces drawdowns few can survive.

Protect against the tail

• Remember a stop caps loss only when the market trades through it; plan for gaps, circuits and events that jump past it.
• Before a known event, expiry, results, RBI policy, budget, decide in advance to hold, hedge or reduce.
• Assume correlations rise in a crisis, so diversification may fail exactly when you rely on it.
• Keep enough exposure small enough that even a plausible worst case leaves the account solvent and trading.
• Prefer defined-risk structures when expressing a view through options in uncertain, high-volatility conditions.
• Never let a single trade or scenario be capable of ending the account; no idea is worth that.

Follow these and no single trade, streak or shock can take you out, which is the whole aim: to still be trading tomorrow. Preservation does not promise profit, but it guarantees you keep the one thing every edge needs, capital to deploy.
