1. Setup

  1. 1Find a mismatch between fundamentals and an official policy or crowded belief (e.g. a defended currency peg).
  2. 2Write down the thesis and what would prove it wrong.
  3. 3Watch for price starting to move in the thesis direction.

2. Entry rules

  1. 1Open a small test position first.
  2. 2Add aggressively only once price and news confirm the imbalance is breaking.
  3. 3Use liquid instruments (futures, major FX pairs).

3. Exit rules

  1. 1Reverse or exit immediately if the invalidation condition is hit.
  2. 2Take profits as the imbalance resolves and consensus catches up.

4. Risk management

  1. 1Define max loss on the test position (≤ 0.5% of account).
  2. 2Never size up before confirmation.
  3. 3Avoid leverage you can't survive if wrong.

Common mistakes

  1. Confusing a strong opinion with confirmation.
  2. Refusing to admit the thesis is wrong.
  3. Copying the size of a hedge fund.

An educational interpretation of publicly known principles, not the trader's exact proprietary method. Backtest and paper-trade before risking real money. Not financial advice.

The story

On Black Wednesday in September 1992, Soros's Quantum Fund held a large short position against the pound, betting the UK could not stay in the European Exchange Rate Mechanism. The UK withdrew and the fund reportedly made about $1 billion.

His theory of reflexivity argues that market prices and fundamentals influence each other, creating booms and busts.

Lessons for traders today

  • When conviction and evidence line up, size matters.
  • Markets can be wrong for longer than you expect.
  • Be quick to admit mistakes and reverse.
