Several Coins on One Screen: Altcoins Versus Bitcoin

Why put several coins on one screen

In crypto, many coins spend long stretches moving in the same direction as bitcoin. Watching a single altcoin chart, you can't tell whether a rise or drop belongs to that coin or is simply the whole market moving together. Keeping a bitcoin chart alongside as a reference makes the difference much easier to see. If bitcoin is quiet and one coin swings hard, the reason most likely lies with that coin; if everything moves in the same candle, the market-wide explanation fits better. Setting charts side by side isn't about prediction. It's about sorting what is happening right now correctly.

Match the conditions first

A comparison only means something when every panel uses the same conditions. If one panel shows 15-minute candles and another shows hourly candles, the same day looks completely different and you can't judge whether the coins moved together. Different exchanges can close candles at different times and measure daily change from different starting points, and mixing a won market with a dollar-based market drags in the exchange rate and the price gap between domestic and overseas venues. Line up these four things before you start comparing.

• Candle length: every panel you compare uses the same candle length
• Exchange and quote currency: where possible, compare markets on one exchange in the same quote currency
• Unit of comparison: prices differ, so read percentage change rather than raw numbers
• Indicator settings: use identical moving average and band settings in every panel

How to check whether they moved together

Specific points are more reliable than a general impression. Pick a candle where bitcoin moved sharply and see whether the candle at the same time in the other panels moved the same way. Then check whether recent highs and lows formed at roughly the same time in each panel. Keep in mind that direction can match while size doesn't. If an altcoin printed a much longer candle in the same down move, it moved in step on direction but swung harder. What matters is whether the same picture repeats across several large moves, not just one or two candles.

What to check first when a coin diverges

When a coin moves differently from bitcoin, rule out the likely causes one by one before reading meaning into it. Many divergences are explained by things outside the chart.

• Coin-specific news: exchange notices, a listing or a caution designation, scheduled token unlocks
• Volume: whether the diverging candle came with real volume or the price jumped on thin trading
• Quote currency: on a won chart, whether the exchange rate or the domestic price gap is what moved
• Thin hours: whether the move happened late at night or on a weekend when few people trade

How many panels make sense

More panels mean more coins at once, but each panel gets smaller and candles and indicators become harder to read. Even on a wide monitor, the number you can compare carefully is smaller than you'd expect, and on a phone the panels stack vertically, so about four is close to the limit. Choose the layout by purpose. To compare against the market, pin bitcoin and ether and use the remaining panels for the coins you want to watch. To study one coin in depth, you can open it in two panels with different candle lengths, but that serves a different purpose from comparing coins, so the multi-timeframe guide is worth reading alongside.

Common illusions when charts sit side by side

The more charts you open, the easier it becomes to mistake chance for a rule. Watch nine panels and one of them will usually form a convincing shape. Moving together also doesn't tell you which side caused what, or whether it will keep happening. You often hear that bitcoin moves first and altcoins follow, but if you believe it without checking how many candles the lag actually was, it becomes an explanation fitted to the past. Finally, a candle that is still forming keeps changing until it closes, so comparisons between closed candles are steadier.

Check it with this site's live tools

The crypto multi-chart shows live candles for the coins you pick in 1, 2, 4, 6 or 9 panels on one screen. Each panel has its own coin and candle length, so for comparisons set every panel to the same length and use the indicator button to turn moving averages, Bollinger Bands and volume on across all panels at once. Each panel carries an RSI badge, and copying the link lets you open the same layout on another device. To see how closely coins move together as a number, the crypto constellation map measures return correlations over periods from one to ninety days and compares them with the previous period. The multi-timeframe trend table gathers the trends of the top coins by trading value across candle lengths in one table, useful for scanning whether bitcoin and the rest point the same way.

Summary and caution

The core of watching several coins on one screen is keeping bitcoin beside you as a reference, matching the conditions, and separating moves in step from divergences. When a coin diverges, check news, volume, quote currency and time of day first, and don't treat the fact that coins moved together as grounds for the next move. This guide explains how to compare and read charts and is not investment advice. When to buy or sell any coin is a decision for each person based on their own situation.
