Price tells you what happened. Volume tells you how much conviction was behind it. Without volume, you’re only getting half the story.
Volume is the number of contracts (or shares) traded in a given period. Every candle on your chart has a corresponding volume bar beneath it — and that bar tells you how much participation was behind that price move.
A price move on high volume means many traders were active and committed to that direction. A price move on low volume means few people were involved — the move lacks conviction and is more likely to reverse.
The core rule: Volume should confirm price. If they’re not agreeing, one of them is lying — and price is usually the one that eventually corrects.
In a healthy uptrend, the green candles should have higher volume than the red candles. More buyers are showing up on up days than sellers on down days. This confirms the trend has real conviction behind it.
When red candles are consistently printing with higher volume than green candles, it means sellers are more aggressive. Even if price hasn’t broken down yet, the weight of volume is bearish — distribution is happening.
When price breaks through a key resistance level and volume is significantly above average, that’s a high-conviction breakout. Institutional money is participating. The breakout is much more likely to follow through.
Price makes new highs but volume is shrinking with each push. This is distribution — smart money is selling into retail buying. When the divergence resolves, price usually drops sharply on heavy volume.
A massive volume spike at the end of a downtrend — often called a selling climax — can mark a reversal. Panic selling exhausts itself in one big candle. The volume spike shows all the sellers have been absorbed.
Price bounces back up but volume is thin — below the 20-period average. No conviction. These low-volume rallies in a downtrend are classic bull traps. They look like recoveries but they’re just dead cat bounces.
Volume is a built-in indicator on TradingView. Click the “V” panel at the bottom or add it via the Indicators menu. Settings are minimal but the MA overlay is essential.
Adding the MA: In Volume settings → Inputs → enable “Volume MA”. Set to 20 periods. This gives you a reference line so you can instantly see whether a candle’s volume is above or below average — that’s the key question.
Crypto note: Crypto volume data on TradingView varies by exchange. For the cleanest readings on Bitcoin use the Coinbase or Binance chart rather than the aggregated one. Exchange-specific volume is more reliable.
A resistance break on below-average volume is a trap. Wait for the volume bar to be clearly above the MA before committing. If volume doesn’t show up, the breakout is probably fake.
The first 30 minutes and last hour of the US session have the highest volume on NQ and ES. Breakouts during these windows are more reliable than midday moves which happen on thin volume.
Volume divergence + RSI divergence at the same time = very high probability reversal signal. Two independent measures are both showing the same weakening. That’s a strong warning.
BTC tops and bottoms are often marked by enormous volume spikes on the weekly chart — panic selling at the bottom, euphoric buying at the top. These climax candles are some of the clearest reversal signals in crypto.
Wash trading is common on smaller crypto exchanges. Stick to volume data from major regulated exchanges and use it as a supporting signal rather than a primary trigger on altcoins.
Pullbacks in a healthy trend happen on LOW volume. That’s fine — it means sellers aren’t showing up with conviction. But if a pullback comes on HIGH volume, it’s warning you the trend may be ending.
The other half is what’s happening in your head when you’re in the trade. Fear, ego, revenge trading, breaking your own stops — that’s where most accounts actually lose money. Not bad setups.
