Taker Buy Sell Volume/Ratio
This concept is often confusing because every trade requires both a buyer and a seller of the given asset. However, depending on whether the order taker is buyer or seller.

Definition

This concept is often confusing because every trade requires both a buyer and a seller of the given asset. However, depending on whether the order taker is a buyer or seller (whether a transaction occurs at the ask price or the bid price), you can distinguish between long volume from taker seller volume.
Note we unify the unit of return value to USD for each exchange where its contract specification may vary and covers perpetual swaps only.

Interpretation

A Taker buy or sell enables transaction of a financial asset instantly at the current best available price. As takers are increasing it could be interpreted as they are willing to pay more to buy or sell at an instant. Utilizing this feature, we can identify whether buying or selling pressure is great.

By value itself

  • Over values of '1' : Taker buy Volumes> Taker Sell Volume-Dominant Bullish sentiment
It indicates that more buyers are willing to buy coins at a higher price indicating that buying pressure is stronger than the selling pressure. It indicates a strong possibility of price rise and shows the bullish sentiment
  • Under values of '1' : Taker Sell Volumes> Taker Buy Volume-Dominant Bearish sentiment
It indicates that more sellers are willing to sell coins at a lower price indicating that sell pressure is stronger than the buying pressure.

Note

Even if the ratio is above 1 indicating that taker volume is dominant it does not necessarily mean that price is going up. It depends on the variance of volume that was traded on each bid/ask.

Additional Explanation

Taker and Maker

Taker: Taker trade refers to an order that is traded before going on the order book. All market order trades are takers. Maker: Maker trade refers to an order that goes on the order book (e.g. a limit order). These orders add volume to the order book, helping to 'make the market'.

Bid and Ask Price

A maker who wants to buy an asset is willing to place limit orders in the order book at a lower price, and a maker who wants to sell is willing to place orders at a higher price. The bid price is the highest current price a buyer is willing to pay for an asset. The ask price is the lowest current price a seller is willing to sell a security for. There is always a bid price and an ask price in an actively traded asset which continuously fluctuates.
When takers buy at the bid price set by makers, the amount of assets traded between the two contributes to the taker seller volume. This volume is selling volume because it has the potential to move the price down. When takers sell at the ask price, the amount of assets traded contributes to the taker buy volume.This volume pushes up the price.
If the current market has more taker buy volume than taker sell volume, it means there is a tendency to increase the price as more trades occur at the ask price. When the current market has more taker sell volume than taker buy volume, it means there is a tendency to push the price down since there are more traders selling at the bid price.
