Direct answer: what “following big banks” means
In forex, “following big banks” usually means observing publicly available information that may reflect how major banks participate in the market, and then checking whether that information aligns with subsequent price action. You cannot see banks’ exact order flows in real time, and you generally cannot confirm trading intent from public facts alone.
A practical approach is to define what you are trying to observe: changes in macro expectations (where banks often position), shifts in currency supply/demand narratives, or liquidity conditions that affect short-term price moves. Then you verify whether the market behavior you see is consistent with that hypothesis.
How it works: public proxies and explainable inputs
Common, non-sensitive ways to approach this topic include:
- Macro-event alignment. Watch major central-bank or policy-relevant releases and compare how currencies move around them. Banks are active participants in hedging and positioning around these events, but you are still observing market outcomes, not bank trades.
- News and market messaging. Use public statements, research notes, or credible reporting that describe risks and scenarios. This can help you form a testable expectation about which direction volatility or rates pressure might move.
- Positioning and liquidity proxies. When available, indicators about broader market positioning and liquidity can provide context. These do not tell you what a specific bank did, but they can explain why moves were larger or faster.
To “follow” in a verifiable way, you need a time window and a rule for comparing: for example, compare price movement and volatility before and after a particular public event, using the same method across multiple occurrences.
Example checks: how to test your hypothesis
You can run independent checks like:
- Event-to-reaction consistency: If a narrative suggests a currency should weaken on a specific policy expectation, does the market reaction show the same pattern more often than not during similar events?
- Alternative explanations: Ask whether rates, risk sentiment, or another headline could explain the move without invoking the bank narrative.
- Repeatability: Look for similar behavior across multiple weeks or months. One isolated reaction is not evidence of bank-driven trading.
If your comparisons are inconsistent, that suggests the proxy is weak or the hypothesis is incomplete.
Limitations and risks to keep in mind
Several constraints limit how closely someone can follow big banks:
- No direct visibility: Exact trades and internal decisions are typically not observable from public sources.
- Delayed or partial information: Headlines and summaries may arrive after the key action, or may describe strategy without revealing timing.
- Correlation is not causation: Even if major-bank-related narratives often coincide with moves, that does not prove the bank caused the move.
- Rapid reversals: Forex pricing can change quickly as new information arrives, invalidating earlier hypotheses.
Limitations: what you can and cannot conclude
You can conclude whether market moves are consistent with a proxy-based hypothesis, and you can improve your testing process. You cannot reliably conclude that a specific big bank executed trades in a specific direction at a specific time, or that following such information will produce a predictable result.
