#AN017: Dirty Levels in Forex: How Banks Think

In the world of Forex, many retail traders are accustomed to seeking surgical precision in technical levels. Clear lines, pinpoint support, geometric resistance. But the truth is that the market doesn't move in such an orderly fashion.

Institutions—banks, macro funds, hedge funds—don't operate to confirm textbook patterns. Instead, they work to manipulate, accumulate, and distribute positions as efficiently as possible. And often, they do so precisely at the so-called "dirty levels."

But what are these dirty levels?

They are price zones, not individual lines. They are areas where many traders place stop losses, pending orders, or breakout entries, making them an ideal target for institutional players. The concept of a dirty level arises from the fact that the price fails to respect the "perfect" level, but breaks it slightly and then retraces its steps: a false breakout, a trap, a hunt for stops.

Banks are very familiar with the behavior of retail traders. They have access to much more extensive information: aggregated positioning data, open interest in options, key levels monitored by algorithms. When they see concentrations of orders around a zone, they design actual liquidity triggers. They push the price just beyond the key level to "clean" the market, generate panic or euphoria, and then initiate their actual trade.

How are these levels identified?

A trader who wants to operate like an institution must stop drawing sharp lines and start thinking in trading bands. A dirty level is, on average, a zone 10 to 15 pips wide, around a psychological level, a previous high/low, or a breakout area. But technical structure alone is not enough. It's important to observe:

Volume density (volume profile or book visibility)

Aggregate retail sentiment (to understand where stops are placed)

Key option levels (especially gamma and maximum pain)

Rising open interest (as confirmation of institutional interest)

When a price approaches a dirty level, you shouldn't enter. You should wait for manipulation. The price often briefly breaks above that range, with a spike, and only then does it retrace its steps in the opposite direction. That's when banks enter: when retail has unloaded its positions or been forced into trading too late. The truly expert trader enters after the level has been "cleaned," not before.

This type of reading leads you to trade in the opposite way to the crowd. It forces you to think ahead: where they want you to enter... and where they actually enter. And only when you begin to recognize these invisible patterns, when you understand that the market is not linear but designed to deceive you, do you truly begin to become a professional trader.

Conclusion?

Trading isn't about predicting the price, but predicting the intentions of those who actually move the market. Dirty levels are key. Those who know how to read manipulation can enter profitably, before the real acceleration. And from that moment, they'll never look back.
