During my 13-hour flight, I watched a movie called "Pressure", it's about the Allies' preparations for the D-Day invasion. One of their biggest challenges wasn't military strategy, but forecasting the weather.
Two meteorologists were tasked with giving the generals a simple answer: Go or no-go?
The problem was that they disagreed.
One relied on historical data, arguing that similar conditions over the previous 50 years had always produced clear weather, so that means it will be clear, guaranteed. The other believed broader weather patterns suggested a major storm was approaching and questioned whether anyone could guarantee the weather 3 days in advance, and whether five historical occurrences were enough to confidently predict the outcome.
The generals preferred the clear-weather forecast because it supported their plans. But the general ultimately considered the alternative forecast and delayed the invasion by 24 hours.
It turned out to be a great decision because not only was there a massive storm that would have compromised the mission, but the Allies also won the war.
So, what does this have to do with trading?
I think there's an important lesson here.
Most retail trading strategies revolve around indicators and identifying chart patterns that have worked historically. But in an incredibly competitive and efficient market, does recognizing a handful of historical patterns actually provide a meaningful edge?
Just because something has worked in the past doesn't mean you understand **WHY it works, under what conditions it works, or when those conditions are no longer present.**
The same distinction applies to trading. You can spend years studying indicators and chart patterns, but if you aren't considering the broader market environment, positioning, sentiment, fundamentals, and the forces influencing price, you may be missing important pieces of the puzzle.
The goal isn't to find another indicator or a better-looking chart pattern. It's to develop a broader understanding of the market that gives you a genuine reason to believe your trade has an edge.
