TRADING SYSTEM

Define the risk first. Then choose the trade.

From CANSLIM × SEPA stock selection, options strategy, position building and management to trading psychology — this page is the complete map of the PVL trading system, and every section links to real, readable work.

POSITION

Position Building & Management

Add only when right; leave when wrong. Pyramid sizing, the 1 RU risk unit and three-stage systematic building — position size is a rule, not a feeling.

ALLOCATION & HEDGE

Allocation & Hedge

Beyond trading, one more line of defense

Rebalancing, cross-asset hedging, ETF allocation and DCA — the system controls single-trade risk; allocation absorbs portfolio risk. Full coverage lives in the Asset Allocation desk.

PVL RULES

The Four Hard Rules

01

5% Risk Unit

Define the maximum acceptable loss before every trade, so no single mistake can break the account.

02

The Four-Layer Defensive Screen comes before strategy

If the underlying fails the screen, no premium is attractive enough to be an opportunity.

03

Invalidation is written before entry

Price, fundamental and time conditions are set before emotions show up.

04

Review fixes the model, not the memory

Keep the original assumptions and evidence, so you know whether judgment or execution failed.
