Reading a Chart Without Fooling Yourself

Reading a chart without fooling yourself

A price chart is a record of what already happened. It is genuinely useful for that — but the mind is extremely good at finding patterns in noise, and a chart is exactly the kind of thing where that tendency gets expensive.

The basics

Most charts on the platform are candlesticks: each candle shows the open, high, low and close price for one period (a minute, an hour, a day — you choose the timeframe). A hollow or green candle usually means the close was above the open for that period; a filled or red candle means the opposite. Zooming out to a daily or weekly timeframe shows the larger trend; zooming into a 5-minute chart shows the same instrument looking far more chaotic — neither view is more true, they just answer different questions.

Support and resistance are price areas where buying or selling pressure has previously stalled a move. They are genuinely observable on a chart, and they are also zones, not exact lines — treating 1.0850 as a precise wall the market cannot cross, rather than a rough area where reactions have happened before, causes a lot of avoidable losses when price pushes 3 pips through it and reverses your stop.

The trap

Here is the honest problem with technical analysis: after a move has already happened, it is very easy to draw a line, a triangle, or a "head and shoulders" shape that explains it perfectly. That is hindsight, not prediction. The test of whether a pattern means anything is whether you can define it in advance, in words specific enough that someone else could apply the same rule to new, unseen data — a shape you can only see after you already know the outcome does not qualify.

A concrete example

Suppose EUR/USD has traded between 1.0800 and 1.0900 for two weeks. A trader buys at 1.0805 because it is "near support," with no stop, expecting a bounce back toward 1.0900. Price instead breaks below 1.0800 and keeps falling — the "support" was a description of the past two weeks, not a rule about the future one. The lesson is not that support and resistance are useless — it is that a chart level is one input into a plan that already has a stop loss and a position size decided in advance (Lessons 4 and 5), never a substitute for either.
