Editor's Note: This is the second part of a 3-part special series on building investing discipline — using crypto as the test case. Part 1 covered how to keep your emotions in check when volatility spikes.

Price charts can be intimidating. They can also be addictive. Our goal here is to give you just enough to understand what a chart is actually telling you, without turning you into someone who stares at candlesticks at 2 a.m. Here's how to look at a chart, take in key signals, and close the tab — without overthinking it.

The basics: price and volume

Most charts include two fundamental elements: price and trading volume. The chart below shows how Bitcoin's volume corresponded with major price swings between 2020 and 2025 — the 2021 bull run, the 2022 crash, and the 2024–25 rally. In each case, the biggest moves coincided with the tallest bars. That's a pattern worth recognizing: High volume can reinforce price movement, signaling a stronger conviction in the market. And that conviction can be held by many traders or just a few acting at scale.

Support and resistance: Think floor and ceiling

Two of the most useful charting concepts are support and resistance levels. A support level shows a historical floor – the price at which an asset has repeatedly stopped falling. Resistance shows a ceiling, where the asset has historically stalled on its way up.

When a price approaches a support zone, it's worth paying attention. Historically, that's where buyers have stepped in. It doesn't mean they will again, or that the price will go up, but it does mean you're not in uncharted territory. The same logic applies for resistance: If an asset has repeatedly failed to break above a certain level, that ceiling is worth knowing about before you read too much into a short-term rally.

There can be more than one support and resistance level for an asset, given that market dynamics change over time (think: a breakthrough moment.) The chart below shows Ether (ETH) with two support zones (S1, S2) and two resistance zones (R1, R2).

Moving averages: Cutting through the noise

A moving average (MA) smooths out daily price swings by tracking the average price over a set number of days — commonly 200 days for long-term trends, and 50 days for shorter-term shifts.

In the chart above, note how Bitcoin (BTC) spent most of 2023–2025 above the 200-day moving average, with two deeper dips in 2025.

When a price is trading above its 200-day moving average, it indicates that the longer-term trend is still upward. A drop below is worth noting — though brief dips don't necessarily signal a lasting reversal. Whether you act on these signals or not, having this insight can help you quickly gauge whether you're looking at strength, weakness, or something in between.

The trap to avoid

Chart literacy has a well-known dark side: It can mislead you into feeling like you can predict the future. You can't. Nobody can, consistently. The research on retail traders attempting to time the market based on technical signals is, on the whole, discouraging.

No chart can reliably answer the question "Is now the exact right time to buy?"

The most useful way to approach chart-reading is not as a predictive tool – but a diagnostic one that can help you understand the current landscape. Is this asset in a defined downtrend, or is it consolidating before a potential move? Is the trading volume confirming what the price is doing, or contradicting it? Charts can help provide answers to these questions.

A practical routine

Think of chart-reading as learning to check the weather. You're not trying to control it. You're just trying to dress appropriately.

If you want to check in on your crypto without it consuming your week, one simple habit can help: Once a week, look at a medium-term chart (for example, the past 60-90 days) for any asset you hold. Note where it sits relative to its 200-day moving average. Check whether recent price moves were accompanied by meaningful trading volume. Then close the tab. For most long-term investors, that level of attention is enough.

The goal is context, not control.

Stay tuned for the final part of our series: There's more to crypto than Bitcoin. How to evaluate other altcoins.
