Buy versus Sell Volume
Why This Matters
Total volume tells you how much a token traded, but it doesn't tell you *who was in control*. Two days can show identical volume numbers and mean completely different things. Learning to separate buy volume from sell volume helps you read whether demand or supply is winning, and whether that battle is actually moving the price.
What Buy and Sell Volume Actually Mean
Every trade has a buyer and a seller, so in one sense all volume is "matched." But most charting tools split volume by which side initiated the trade:
- Buy volume: trades that hit the ask price (someone was willing to pay up to get filled)
- Sell volume: trades that hit the bid price (someone was willing to accept less to get out)
When buy volume consistently outweighs sell volume, it usually means buyers are more eager than sellers — they're willing to chase price. The reverse suggests sellers are more motivated to exit than buyers are to enter.
The Key Insight: Volume Without Price Movement
This is the part traders skip past too quickly. High volume with a big price move is easy to explain — lots of buyers pushed price up, or lots of sellers pushed it down. But high volume with little or no price movement is a different signal entirely.
It usually means one of two things:
- Absorption — one side is aggressively buying (or selling) heavy volume, but a large, patient counterparty is soaking it up at a stable price. Someone with size is willing to sell into all that buy pressure without letting price run, or buy into sell pressure without letting it drop.
- Exhaustion — both sides are trading a lot, but neither has conviction to push price further. This often shows up near the end of a strong trend, right before a reversal or a stall.
Either way, flat price on heavy volume tells you something is happening beneath the surface that a simple price chart won't show you.
Solana Example
Imagine a mid-cap Solana token trading around $0.85. Over a normal hour it does $40,000 in volume and moves maybe 1-2%. Then one hour shows $400,000 in volume — ten times normal — but price only moves from $0.85 to $0.86.
That's a red flag worth investigating, not ignoring. Ten times the usual volume with almost no price change means a huge number of buyers were absorbed by an equally huge number of sellers (or one large seller). If you only looked at price, you'd think "nothing happened." If you looked at volume alone, you'd think "big move incoming." Looking at both together tells you a real supply-versus-demand fight occurred, and right now supply is winning quietly. Watch what happens next: if buy pressure keeps coming and eventually breaks through, that absorbed supply may be running out. If buy volume dries up after this, it may have been buyers giving up.
Common Mistake
Treating a volume spike as automatically bullish or bearish based on direction alone. Traders see "volume is up" and assume it confirms whatever the last candle did, without checking whether price actually moved a meaningful amount relative to that volume. A 10x volume spike that produces a 0.5% price move is not the same story as a 10x spike that produces a 15% move — even though both show "high volume."
On MAPLUStrade
MAPLUStrade's chart view lets you overlay buy/sell volume split beneath price candles, so you can see at a glance whether a candle's volume was buyer-led or seller-led. Use the volume-to-price ratio indicator in the toolbar to flag candles where volume is unusually high but the price range is unusually tight — these are the absorption/exhaustion candles worth marking for later review. Setting a volume alert (available in the alerts panel) for "volume > 3x 20-period average" on a watchlist token can help you catch these moments as they happen rather than after the fact.
Recap
Buy and sell volume tell you who's more eager to trade, not just how much traded. When volume spikes but price barely moves, don't ignore it — that's often where the real story is hiding.
