- Details
- Category: Trading Rules
Internal control is one of the key determinants of long-term trading success. The following article is based on the book Trade Your Way to Financial Freedom by Van Tharp.
The Importance of Internal Control
According to Van Tharp, internal control involves three key components:
-
Psychology (60% weight)
-
Position sizing (30% weight)
-
System development (10% weight)
In many ways, trading success is a result of internal control. However, most traders fail to recognize its significance.
-
Internal control is essential for effective portfolio risk management.
-
Traders who commit to developing internal control are the ones who ultimately succeed.
-
Most successful speculators have low win rates (35–50%), yet they remain profitable because their gains significantly outweigh their losses—this requires strong internal control.
-
Successful fundamental investors are often contrarians who wait patiently for the right opportunity before entering a position, which also demands internal control.

(i) growth, inflation, and unemployment
(ii) monetary policies, and especially the interest rate policy of the central bank
(iii) fiscal policies & government spending
(iv) political stability (political risk)
(v) legislation regarding capital taxation & the openness of the domestic economy
New macroeconomic developments can create trading opportunities in the Forex market
The Forex market is highly efficient, with news impacts quickly reflected in exchange rates. However, major shifts in the broader macroeconomic environment can present significant opportunities for traders. In fact, all key Forex trend reversals are driven by such macroeconomic shifts.

Introduction to the Foreign Exchange Market
With daily volumes exceeding USD 5 trillion, the Foreign Exchange Market, or Forex, is the largest financial market in the world. It operates as a decentralized network where the world’s major currencies are traded against one another on a 24-hour basis, from Monday to Friday.
The Short History of the Modern Currency Market
After the end of World War II, the Bretton Woods Agreement (1944) laid the foundation for a new global monetary system. Under this agreement, a country’s currency was pegged to a specific quantity of gold. When the Bretton Woods system ended in the 1970s, it gave rise to the modern Floating Currency System. In this system, the value of each currency fluctuates based on supply and demand dynamics.
- In 1971, the CME (Chicago Mercantile Exchange) became the first exchange to offer currency trading through the International Monetary Market (IMM).
- Following 1990, advances in information technology paved the way for a fully computerized trading environment—today known as the Online Forex Market.

Nassim Nicholas Taleb is a Lebanese-American mathematical statistician, author, risk analyst, and options trader. His work centers on uncertainty, randomness, and probability. He developed the risk-hedging technique known as 'Tail risk hedging' or 'Black Swan protection,' which aggregates portfolio exposure to guard against extreme market volatility. According to the Sunday Times, his 2007 book The Black Swan is one of the twelve most influential books since World War II.
Nassim Nicholas Taleb's Background
Born in 1960, Nassim Nicholas Taleb is a Lebanese-American scholar, former trader, and risk analyst known for redefining how we view uncertainty and randomness. His trading experience on Wall Street shaped his skepticism of traditional risk models.
- Taleb’s key idea is the Black Swan—rare, high-impact events often ignored by conventional thinking. His 2007 book The Black Swan highlights how underestimating randomness leads to major failures.
- He developed tail risk hedging, a strategy that protects portfolios from extreme market swings through asymmetric payoffs—small losses for large gains during crises.
- His Incerto series explores concepts like Antifragility (systems that grow stronger from disorder), Skin in the Game (risk accountability), and the Lindy Effect (longer life for enduring ideas).
- Though sometimes controversial, Taleb’s ideas influence finance, economics, and policy, advocating humility and robust systems in uncertain times.
