- 2Write down the thesis and what would prove it wrong.
- 3Watch for price starting to move in the thesis direction.
2. Entry rules
- 1Open a small test position first.
- 2Add aggressively only once price and news confirm the imbalance is breaking.
- 3Use liquid instruments (futures, major FX pairs).
3. Exit rules

- 2Take profits as the imbalance resolves and consensus catches up.
4. Risk management

- 3Avoid leverage you can't survive if wrong.
Common mistakes

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.
